Load Test Capacity

The desired load test capacity is expressed in kilowatts (KW). KW corresponds directly to engine HP (.746 HP = KW) and is developed exclusively by the resistive load bank. Adding reactive load changes the total KVA of the load, but does not alter the KW or HP load.

A purely resistive load bank provides a realistic and effective test of the prime mover and causes full load currents to be developed by the generator. The engine will develop full rated HP, operating pressures and temperatures, and the performance of the governor will be fully evaluated. Adding inductive load allows for the full KVA capacity of the generator to be developed for a full functional test of temperature rise, waveform quality, voltage regulator response and reactive load sharing.
