However, just if you procure a backup generator, it cannot be used as a defensive strategy against disruptive power threats. Have you given thought to the idea of using load banks to test and maintain the backup power generator? In the case of a power outage, what do you do? Due to insufficient and inadequate load testing, a lot of industry managers have to deal with power disruption problems time and again.
There is a misconception that regular maintenance and a component-by-component test are just enough to ensure smooth functioning and working of the power systems. Just by testing the system’s prime mover and the engine is not sufficient proof that the system is functioning properly. However, still, such maintenance work is conducted to ensure that the equipment doesn’t malfunction. Apparently, only when there is a system failure, then the managers give load bank testing a thought. All the system equipment has many sub-parts, like the alternators, the switchgear, cabling, cooling systems, ventilation, and so on. Simply testing the engine or the individual parts is not enough, it is imperative to opt for load bank testing to ensure the systems work smoothly in any situation.
There are two kinds of load bank testing. One is the resistive load bank, and the other is the reactive load bank. Of the two, the resistive is the most commonly used load bank and serves a lot of functions. Saving an ample amount of time, money, and involvement this kind of load testing solution ensures that the system is working properly. So, let’s look into the insights of this favorite load bank testing process that has been embraced by the majority of industrialists and entrepreneurs.
A bit of information about resistive load bank
This load bank provides equal loading of both the prime mover and the generator. It impacts all the aspects and features of a generating system, and the load is created by converting electrical energy by power resistors to heat. The heat is then dissipated by air, water, or forced means of convection. When testing is conducted, the resistive load simulates real-life loading like lighting and heating loads along with unity power factor modules of magnetic loads of motors and transformers.
The different categories of resistive load banks are:
Test and maintenance of DC power systems – The load bank can be used for testing DC power systems like battery charges, battery equipment, DC generators, and UPS systems.
Test and maintenance of AC power equipment – For the purpose of test and maintenance, a resistive load bank can be used in UPS system generators ranging from 150kW to 3000kW at different sites and for the single location up to 4600kW. For larger and high voltage AC systems the load bank can take power system from 7000kW till 15,000volts. There is AC power equipment that utilizes the radiator airflow to cool down the load elements. These load banks are adaptive and fit in any site conditions or duct dimensions. The power strength can go up to 1200kW. However, the AC power system can use water instead of air for cooling down the resistive load elements and is ideal for places where any kind of operation is conducted in a quiet manner. The power voltage can go up to 2500kW.
Load bank testing is a very effective way to check the power systems. However, you need to find a good service provider for the long haul to make sure they will attend to your needs and requirements with updated knowledge about load testing for ensuring optimal servicing of the power systems.
