AC Load Bank

Regular AC load bank testing of generators provides an essential health check service to prevent diesel engine failure due to wet stacking. Wet stacking occurs due to under loading of the genset which results in wet un-burned fuel building up in the engine. PITE offers the AC load bank which could meet your demands.

  • High rate testing for voltage, current and transient voltage waveform for generator and UPS units
