Resistive load banks are the most commonly used load banks for testing generator sets and power systems. They can provide full KW loading to the power source to completely evaluate the engine cooling, exhaust and fuel systems. They will not load the generator to its full nameplate KVA capacity at 0.8 Power Factor. In order to load the generator to its full KVA rating, reactive load banks will be required.
Q: Should a diesel generator be loadbank tested annually?
A: Yes, this is a critical piece of preventative maintenance to ensure the generator operates while
under full load. We recommend one 2-hour 100% resistive load bank test be performed annually.
