Make sure your generator is ready when needed with load bank testing

For mission critical facilities, such as data centers and hospitals, emergency power generators simply cannot afford to fail. Regularly scheduled maintenance will help to make sure that your generator is ready when it’s called upon. That is why preventative maintenance such as load bank testing is of utmost importance. Load bank testing helps to ensure that your generator will be fully dependable and operational, as well as completely capable of the highest possible load it may be required to handle at any critical point in time.

What is load bank testing?
A generator load bank test involves an examination and assessment of a genset. It verifies that all primary components of the generator set are in proper working condition under loaded conditions.

The test puts a generator under varying load conditions and sees how the machine reacts to the power draw. This is not to be mistaken for the automatic exercising some generators do for a load test. These exercises turn on the device but do not put it under a load. Without testing the generator under load, you will not be able to gauge the health and performance capabilities of the generator.

Why is generator load bank testing important?
When a diesel engine powered genset is not used frequently or only run on light loads, it can be prone to experiencing unburned fuel and soot buildup in the exhaust system. This is called wet-stacking. When wet-stacking occurs, the genset is likely to perform poorly, to endure damage, can become a fire hazard, and can even lead to complete failure.

During a load bank test, the generator is allowed to run at full power and full temperature. This will cause any wet-stacking to burn off. Hence, a load bank test can determine whether the generator will function properly and efficiently on all levels, and eliminates any wet-stacking that may have built up within the generator.

Benefits of load bank testing
There are multiple reasons gensets should undergo a load bank test on an annual basis, including the following:
– Verifies the gensets capabilities opposed to just routinely starting it up
– Problems discovered early can be significantly less expensive and prevents future major issues
– Helps to avoid wet-stacking and cleans out carbon deposits
– Verifies the engine cooling systems will perform while under load
– Provides assurance that the genset should work properly when you need it most

GreenBay’s load bank testing of gensets is a wide-ranging service that monitors every critical component of your generator, including the engine temperature as well as the oil pressure. Throughout the testing process, we oversee the entire unit, ensuring that it runs at normal operating pressures and temperatures once optimal levels are achieved. Our aim is for your standby generator to operate more efficiently, thereby guaranteeing the unit is working exactly as it was designed to do.

System efficiency and reliability starts with preventive maintenance

Data centers as well as other critical infrastructures are changing rapidly. Therefore, it is more important than ever to ensure that each component of the support infrastructure is operating at maximum efficiency and reliability. One of the most important ways to do so is preventive maintenance.

We will look at preventive maintenance of 4 major systems – UPS (uninterruptible power supply), very early warning smoke detection, cooling and precision air conditioning, and clean agent fire suppression.

UPS System

While numerous backup power UPS components are susceptible to failure, a preventive maintenance service plan ensures these parts (such as batteries, capacitors, air filters, component connections and redundant power supplies) are regularly examined. This greatly reduces the risk of a load loss and extends the overall lifespan of your UPS. Preventive maintenance dramatically improves the performance, availability and service life of critical equipment and significantly reduces the number of issues that your equipment experiences.

Very Early Warning Smoke Detection System

To maintain the system at its peak performance level, its suggested maintenance schedule should be followed. Its optimum operation requires that the equipment is supported by a well-designed and maintained sampling pipe network. The site conditions and the local codes and standards may require more regular maintenance than that recommended by the system provider. Maintenance frequency must be increased in industrial applications such as factories, distribution facilities and warehousing with high vehicular traffic loads since these applications commonly have high levels of background pollution.

Cooling & Precision Air Conditioning System

Precision cooling systems have been designed specifically to meet the needs of critical infrastructure heat loads and have very different service and maintenance needs than standard building air conditioning, which is designed for occupant comfort. Technologies such as digital scroll compressors, high density in the row cooling, and variable speed drives require advanced controls to be configured and networked properly. Preventive maintenance for cooling equipment should focus on such key components as air filters, blower drive systems, compressors, facility fluid and piping, and evaporator coils.

Clean Agent Fire Suppression System

Clean agent systems are particularly well suited for sensitive environments such as telecommunication sites, data centers, power plants, laboratories, art galleries, and more. This system is a great option for any enclosure that you may not want to use a sprinkler or risk getting the high value assets wet. But they must be properly maintained, which requires regular inspections and maintenance. A strict maintenance schedule would include, amongst others, verifying clean agent cylinder weight, room integrity testing and testing all clean agent system control panel equipment, container inspection, and hydrostatic test.

Remember that it is important that components in the support infrastructure of a critical facility are well-maintained. The systems are only as beneficial to safety as their own safety status. The priority is to work with manufacturer-backed industry experts such as GreenBay, to help you set up and implement a holistic inspection and maintenance strategy for your critical infrastructure.

Our certified technicians are factory-trained with extensive knowledge and hands-on experience on how to maintain these major systems to maximise performance and efficiency.

Preventive maintenance for your data center made easy with GreenBay!

An ounce of prevention is worth a pound of cure. This cannot be more true for data center maintenance. Effective maintenance strategies help protect your data center from unplanned outages, and reduce repairs and downtime related costs. Shutting down of data center can cost millions of dollars to big facilities.

For the maintenance of your data center to be effective, a comprehensive maintenance strategy must be in place. It includes the following:

Regular inspections

Your data center management staff can carry out the inspections, regular monitoring and checking for poor efficiency use and alarm alerts.

Predictive maintenance

This can be done via a monitoring system. Your onsite staff will monitor trends and measure specific data to predict the potential end of life equipment in the data center.

Corrective works

They help prevent imminent failure through timely procurement of end-of-life equipment and prompt faulty parts replacement.

Preventive maintenance

Equipment should get tested, cleaned, adjusted, and replaced through a planned maintenance schedule to ensure optimal performance at all times.

Preventive maintenance

One of the best ways to ensure minimal amount of equipment failures and shutdowns is to perform preventive maintenance. Preventive maintenance conduct scheduled analyses to catch the defect before occurring. Having a plan in place and executing on it regularly will help avoid unplanned downtime due to battery failure, clogged air filters, and other physical causes which could lead to a crisis in critical infrastructure.
Amongst others, preventive maintenance should include checks on equipment such as switches and routers, circuit breakers, power supplies, cabling, HVAC systems, fire detection, and prevention systems.

Why is preventive maintenance important?

1. Reduces the risk of data center failure
There are high chances that your data center shuts down because of loads of data. That is why maintenance is crucial to avoid interruptions in data storage, access, and retrieval. Shutting down data centers does not only affect the accessibility of data but can also be very costly.

2. Management of operational costs
Preventive maintenance is not only about extending the lifespan of your data center but also managing operating costs. Data centers consume massive energy amounts. One way to lower operational costs is to make sure that your equipment works efficiently by solving or fixing issues in the system.

3. Preventing the risks of downtime
For data centers to keep running through unforeseeable power issues like utility spikes and power outages, most of them depend on the reliability of UPS or Uninterruptible Power Supply systems. Preventive maintenance must be in place to maximize the performance and reliability of the UPS systems by providing systematic detection and correction of failures.

4. Safety of people, equipment and facilties
Safety systems such as VESDA aspirating smoke detection (ASD) which enables early detection and mitigation of potential fire threats, must be regularly maintained for performance and reliability to avoid potential disasters which can cause injury, loss of life and equipment damage.

5. Reducing environmental impact
In the industry of data centers, sustainability must be a priority and should form an integral part of all development strategies moving forward. While the focus remains on green data center strategies, companies can strive to achieve a balance between reduced energy consumption and increased performance by prioritising preventive maintenance.

Huawei’s cooling solutions makes green data centers possible

For data centers, cooling systems consume the most power, and so reducing the energy consumption of cooling systems represents a first crucial step towards a greener data center. While innovation and technology has brought much advancement in the use of natural cooling sources, cooling systems need smart brains that are capable of smart adjustments and on-demand cooling with the constant changes in data center loads and their environments.

For example, China Unicom’s Henan branch (China Unicom Henan) deployed Huawei’s iCooling@AI solution which integrates big data and AI, enabling data centers to learn to save power and automatically optimize their power efficiency, improving data centers’ PUE by 8 to 15 percent.

Located in Henan’s Zhengzhou, the Central Plains Data Center is one of China Unicom’s 12 planned, ultra-large, national data centers. It’s also the only core data center in central China to be built to the T3+/T4 standard. At the start of this strategic partnership project between China Unicom and the Henan provincial government, China Unicom Henan put forward rigid energy consumption requirements for the data center. Its priority was to achieve reliability and a PUE that would be first-class both in China and globally.

In the days before the iCooling@AI solution was adopted for optimizing power efficiency, data center cooling systems were mainly configured manually. This made it difficult to achieve satisfactory results, as the load and environment were constantly changing.

In contrast, iCooling@AI can efficiently and accurately collect all data relating to a data center’s power efficiency. It then uses the deep neural network for modelling and accurately compares the created models with the data center’s operating status, which is optimized every hour. As a data center’s load increases, the cooling mode changes and the AI becomes more capable of learning. This leads to constant improvements in power saving that significantly reduce power consumption and waste.

With the adoption of the iCooling@AI solution, components of a data center cooling system will collaborate intelligently and operate efficiently, optimizing the entire system’s power efficiency.

Huawei deploys a green data center for China Mobile in just 6 months!

Xi’an, located in Northwest China, is one of the most historical cities in the world, serving as the capital for much of ancient China. Home to the famous Terracotta Army, the city receives hundred of millions of tourists every year.

Droves of tourists bring massive torrents of data. According to third-party database company Statista, 2021 saw a 79 Zettabyte (ZB) increase in data volume, the equivalent of approximately 79 billion Terabytes (TB). Such dramatic increases in data volumes put heavy strains on operators, and those in Xi’an are no exception to this trend.

In order to deal with an influx in mobile data, China Mobile set an ambitious goal to build its new and green Xixian Data Center (Shaanxi) in Xi’an. In collaboration with long-term partner Huawei, they decided on a solution that involved combining a prefabricated modular data center with indirect evaporative cooling technology to achieve a quick service rollout while prioritizing green and low-carbon results.

The data center was divided into 232 modules with the equipment all prefabricated and preinstalled in the factory. Then, after completing onsite preparation, LEGO-like construction was performed. This allowed engineers to complete the entire service rollout in just six months, with construction waste and dust slashed by 80%, and a material recovery rate exceeding 80%.

Huawei’s indirect evaporative cooling technology, however, capitalizes on Xi’an’s climate, drawing air from the surroundings to cool the facilities. Powered by Artificial Intelligence (AI) technology, the air compressor is only needed for two months of the year, with the facility relying on natural cooling for the other 10 months, reducing the cooling system’s energy consumption by more than 50%. As such, over a 10-year cycle, nearly 60 million kWh of electricity is saved, alongside 400,000 tonnes of water, which translates into slashing carbon emissions by 27,000 tonnes, the equivalent of planting 37,000 trees.

Huawei recently delivered a prefabricated modular data center for Safaricom as the telco begins to ramp up operations and launch a mobile network service in Ethiopia.

The Application Series: How to determine the reliability of a data center for a financial insitution

In a digital age, businesses increasingly rely on data centers to deliver high-availability environments that support their mission-critical workload.

With financial institutions, every minute of downtime can impact revenue, productivity, customer satisfaction and reputation. The cost of an hour of downtime can range from $1 million to more than $5 million, excluding legal fees, fines and penalties. This number can climb to millions per minute if the outage interrupts a major business transaction or occurs during peak business hours.

Given the potential of a severe financial burden, financial institutions need a data center that can deliver the reliability that matches their uptime requirements.

How do you measure data center reliability?

Uptime Institute’s Tier Standard is the globally recognized standard for data center reliability and overall performance. Founded in 1993, the Uptime Institute has been dedicated to the exploration and study of data center infrastructure.

In 2005, the Uptime Institute designed the data center Tier Classification System which offers a consistent and objective international standard for data center performance. The capabilities of a data center escalate as you graduate from Tier I, which offers the least reliability, to Tier IV, with the most.

The Tier Classification System

Each tier includes the requirements of the previous level as you move up the tier ladder.

As the most basic level, a Tier I data center extends no guarantee of redundancy for any critical systems. At a minimum, the Uptime Institute requires it to offer a UPS; a designated space for IT systems; dedicated cooling equipment that runs outside of office hours; and an engine generator.

Tier II data centers build on the requirements of Tier I to include some redundant components. While this partial redundancy improves reliability to 99.741% uptime yearly, these facilities still utilize a single distribution path for power and cooling and are still susceptible to unexpected interruptions.

The architecture of a Tier III data center offers the capacity to support the full IT load and also offers an additional component for backup purposes, so performance is not impacted if a single component fails. The level of redundancy here offers concurrent maintainability, meaning that each critical component or distribution path can be shut down for planned maintenance without affecting the IT environment. However, Tier III data centers can conduct routine maintenance without impacting service, but are still at risk of downtime during unscheduled events.

Tier IV data centers are the most sophisticated tier certified by the Uptime Institute. Offering a completely independent architecture that duplicates every critical component of the primary architecture and provides multiple distribution paths, this fault-tolerant design provides twice the capacity required to operate at full IT load. This tier is generally populated by government organizations and large global enterprises with mission-critical servers and intense customer or business demands.

For industries with mission-critical workloads such as the financial sector, data centers must be reliable and that operations are not derailed due to system failure or natural disaster. The Tier Classification System provides a guide on the data center tier level that can best balance your risk tolerance and budget.

The Application Series: Spotlight on the Importance of Data Centers for the Financial Sector

The financial sector is dealing with an increasing volume of data to be managed – data which must be stored securely and data which must move fast. Here’s a look at the many ways that the financial sector rely upon data centers.

Electronic trading drives demand

The shift to electronic trading has been a significant factor in the financial sector’s use of data centers. It has increased access to financial market data, allowing anyone with an internet connection to get involved in stock trading. Trading happens all over the world, and data centers must handle the demand and perform consistently.

Big data processing and analytics

The popularity and use of Big Data increases every year, which ultimately improves understanding of clients’ needs, their experience and behaviour models. According to the research conducted by IDC research, the banking sector invests the most money in the analysis of Big Data. This can be explained by the increase in the number of solutions and products created by FinTech companies specifically for banks to manage assets and liabilities.

This reliance means data centers must deliver high-availability environments that support their mission-critical workloads. For institutions in the financial sector, data center uptime is of upmost importance. Stay tuned for the next article in The Application Series as we explore data center uptime and performance.

The Application Series: Protecting the Telecommunications Industry

Critical infrastructure’s top priority is to assure safety, health and welfare for all citizens.

According to the United States government’s Cybersecurity & Infrastructure Security Agency (CISA), critical infrastructure is the power used in homes, the water we drink, the transportation that moves us, the stores where we shop, and the Internet and communications we rely on to maintain our contact with friends, family, and colleagues.

With the Covid-19 pandemic, it has become undeniable that the communications industry is an integral component worldwide in terms of economy, public safety, businesses, and even interpersonal relationships.

There are many aspects needed to support and help the telecommunications industry achieve true resilience, and to protect infrastructures from various challenges. Here, we outline some of the most vital services which are often neglected.

UPS system

Telecommunications companies, which must maintain the infrastructure in addition to data storage and backup, depend on uninterruptable power supply (UPS) systems. They ensure that the landline, internet and mobile communications function nationwide. Therefore the right UPS system is extremely important to maintain the network until a power failure has ended or an emergency generator takes over.

Very early warning aspirating smoke detection

Protecting these telecommuncations infrastructures against fires is vital but detecting the early signs of a fire can be a real challenge. Very-early-warning aspirating smoke detection can reveal the earliest signs of fire threats to help telecommunications operators potentially prevent disruption from fire that can put people, assets and data at risk.

Precision air conditioning

As telecom equipment generates large quantities of heat in small areas, six to ten times the heat density of normal office space, the air conditioning system must have more than just enough cooling capacity. It must have the precision to react quickly to a drastic change in heat load and prevent wide temperature fluctuations.

As 5G and the IoT move to center stage, telecommunications services provider have become key instruments to lead society in the new phase of the information era. At GreenBay, we provide these important services (and more) to assist telecommunications operators to provide the reliability of services that is expected from them.
