- Conclusion: Why Load Testing Is Essential for Power System Reliability
Saying that reliable power is necessary is, for sure, an understatement. It should be perceived as something that’s mandatory, not optional, because without it, no business would ever be able to function normally.
It’s safe to say that the vast majority of facilities rely on it, starting from data centers, commercial buildings, healthcare institutions, and many others. Uninterrupted power is here to keep all of them going, and, concurrently, safeguard the most crucial systems.
For unknown reasons, a lot of modern companies firmly believe that their backup power will continue to work seamlessly at any given moment, without testing it under real-world conditions.
Reliable testing can only be executed with load testing, which is intended to make sure that power systems are still going strong even during outages or any other inconveniences. The importance of it cannot be emphasized enough, and if you’d like to know why it’s so crucial, then stay tuned to learn more!
Why It’s Essential For A Power System To Be Stable And Reliable?
To put it simply, power systems can be described as a very intricate network that consists of switchgear, generators, control systems, and cabling. Even though it’s always recommended to perform regular maintenance and inspections, bear in mind that these things cannot guarantee that everything’s fine with them, and that they’ll be capable of performing impeccably even under stress.
At first glance, everything may appear to be great. This refers to the situations when a power system isn’t too loaded; however, things may not be as good when an urgency strikes. That’s precisely why it’s of huge importance for your firm to ensure your power system is perfectly reliable, and that it’s able to handle any situation, even the most challenging one.
The only way you can be certain of this is through load testing. It’s designed to offer you some sort of guarantee that your power system will never fail you.
Learning More About The Load Testing
You’ll hardly ever deal with any type of failure of your power systems during regular inspections. That’s something that occurs when they are under pressure, and the only way to figure out whether they are strong enough is to put them in a real-world scenario, because that’s one of the surefire ways to assess backup and standby power equipment.
Bear in mind that running a generator without an electrical load will not show you whether your power system will perform well during an outage. And that’s the moment where you should allow generator load banks to step in. By employing controlled loads, your technicians can effectively replicate real operating conditions without jeopardizing your organization.
Additionally, this whole process gives engineers an opportunity to see how frequency, voltage, and cooling systems work when the demand is increased. In these instances, they’ll be able to easily determine if there’s any electrical or mechanical issue, and if God forbid there is, they’ll be able to address it on time, before it escalates.
The bottom line is that load banks are here to offer you accurate control over test conditions. This allows you to decrease or increase demand in measured steps, making sure your generator is reliable and strong enough.
Load Testing & Backup Power Systems
Oftentimes, backup power systems are in so-called idle mode for a certain period of time. Seemingly, this may be a good thing; however, when they are inactive, this can result in a bunch of different problems, ranging from carbon buildup, fuel degradation, component failure, etc. On a more positive note, when you put your trust in the hands of load testing, it’s going to effectively resolve these issues by:
- Keeping wet stacking at bay (referring to the diesel generators)
- Making sure generators can tackle full rated capacity
- Giving you a guarantee that you are adhering to the regulatory and safety rules and regulations
- Uncovering electrical and/or mechanical problems that aren’t easily noticeable
- Verifying the right integration with transfer switches
What Are The Most Common Load Banks?
Now, before you start conducting any tests, bear in mind that every power system needs a different testing method. If you aren’t familiar with the most common kinds of load banks, then it’s time to get your facts straight.
- Reactive load banks – They encourage capacitive and inductive loads, like transformers and motors, offering a very realistic test of electrical performance
- Resistive load banks – These encourage basic electrical loads, like heating and/or lighting. They are generally perfect for testing engine performance and basic power output.
- Mixed load banks – It’s safe to say that these are a great blend of the reactive and resistive elements, which makes them perfect for comprehensive testing of the cutting-edge power systems
Why is it so important to learn more about the load banks? Only then will you be able to select the right one that will ensure accurate testing is performed.
Boosting Fuel Efficacy & Engine Health
Diesel generators demand periodic operation under load to retain engine health. It’s worth mentioning that running these generators at low loads for a very long period of time is certainly not a good idea, because it will result in wet stacking, during which unburned fuel is piled up in the exhaust system.
However, if you utilize load testing that employs generator load banks, it’s going to help you:
- Take the fuel efficacy to the next level
- Burn off carbon deposits
- Extend the life of your engine
- Maintain optimal combustion temperatures
Something like this will not only level up reliability, but it will also decrease the costs you’ll have that are related to maintenance.
You’ll Keep Generator Failures At Bay
The vast majority of generator failures happen because the testing wasn’t performed on a regular basis, not because their design wasn’t good enough. Through load testing, you can detect lots of problems, such as:
- Loose electrical connections
- Poor fuel delivery
- Voltage regulators that aren’t effective enough
- Control system issues
As you can see, load testing is truly a necessity, because without it, you’d never be able to tell whether your power systems will be “prepared” to work normally even when demand is extremely high. That’s how pivotal it is!
