Different kinds of climatic calamities and sometimes artificial electrical damages cause power supply interruptions and blackouts. For these reasons, plant owners have sought out financial insurance for time loss and machinery damage. They have also installed backup electric supplying equipment to beat emergency. However, simply installing an added power generator may not solve the problem permanently and protect against climatic threats. Testing the backup power mechanism is important along with maintaining it to run the plant’s operations smoothly. A large number of managers are still not aware of the problems of their electrical backup systems and hence work with underperforming machines. Loadbank testing can help in finding the health of the backup system.

Inadequate Testing

There is a myth that by testing the backup system’s components on by one will provide insight on the quality of the system and its ability to support unplanned downtime. There is also a belief that examining the system’s engine will provide adequate evidence to the system functioning properly. However, these do not stand the test and managers most of the times find that they are unable to handle the untimely loss of power supply. The backup system malfunctions and they cannot bail the plant out of this messy situation. The backup system usually consists of a number of components like ventilation, cabling, switchgear, fuel system and other stuff which are manufactured and assembled for the system to function. Thus, examining the components separately will not help in finding out the condition of the system. It is important to examine the system as a whole to find out the flaws that prevent the machine from performing optimally.

How Resistive Loadbank testing Helps

Resistive Loadbank testing can save money and time for the business owners and plant managers. It can also save physical labour by producing an electrical load that will be applied to the backup generator to detect impending problems with the entire backup system. However, there is one significant disadvantage of resistive loadbank testing; it is unable to account for the whole plant’s emergency preparedness. The reason behind this is that the electrical power consumption of a plant is much higher than what the resistive loadbank testing can cover for examination. Therefore, the objective of this examination is that it will reveal the proper functioning of the engine of a backup power system. However, it is unable to recognise and rectify potential issues with the whole backup power supply system.

Resistive/Reactive Loadbank is the Answer

In such a situation, resistive/reactive loadbank testing can be the answer. This very much indicates a combination of resistive and reactive loadbank testing. This can be helpful in finding out the backup system’s actual performance in an altering load pattern which comes closer to a real-world electrical power supply disruption. This combination tests the components separately as well as the entire system to ensure that it can function smoothly and handle tough conditions like power supply disruption. Unplanned power disruptions and the weakness of backup system can only be detected by a combination of resistive and reactive loadbank testing.
