How Load Bank Testing Can Improve the Performance of Generators

Posted last August 22, 2017, 7:32 pm in Services report article

When power backup generators fail to perform in emergency situations, businesses face great losses. It becomes extremely important for companies to keep their power backup systems in good working condition in order to avoid inconvenience. The prime function of load bank testing is to maintain power generators by uncovering potential operational issues. Load bank testing helps engineers determine:

  • The overall performance of a unit

  • The capability of a unit to deliver the required power

  • The performance of a power system under varying loads  

  • Voltage regulator response time   

Load banks test and improve the overall performance of a power generator and its components. It also helps operators remove fuel deposits from the system. The article will illustrate the benefits of load bank testing and how it can improves the performance of power systems. Load bank testing will help verify the following key operations of a power system:

Voltage regulator operations

The voltage regulator is a key part of power generators. It enables the system to deal with load changes. It becomes impossible for a system to recover if the regulator is not working properly. In order to verify the performance of voltage regulator, we use either resistive or inductive load bank testing.  When heavy loads are applied, engine speed decreases before it recovers to its normal state. We name the recovery interval as transient response.

Cooling system operations

Load bank testing is applied to understand and highlight the weaknesses in the cooling system. The test let the generator inject additional heat into the cooling air stream. The process will also put stress on the thermostat, oil cooler, and radiator. This method generates valuable temperature data which can be used to verify various operations. It also helps operators determine the health of temperature alarms.  

Governor operations

The role of governors in a power generator is to monitor the speed of engine under various load conditions. Electronic governors and velocity governors are two of the main types of governors. The function of electronic governors is to control the engine speed electronically.

 

All the components in a generator set should work efficiently and harmoniously in order to produce maximum results. Load bank testing plays a vital role in keeping your generators in good shape. You can improve the performance of your power backup units by obtaining necessary information through the testing process and using that information to manage generator operations in an efficient manner. Keep your power systems in good working conditions all the time in order to get the backup whenever you need it. It is important to consult an experienced and reliable company which provides load bank solutions.
