Jun 17, 2002 · If the generator is a standby unit, utilize a constant voltage transformer in the control system power supply, such as a Sola CVS. This will keep the voltage to the control relays to within 95% of nominal voltage with up to 30% dip on the primary. Recovery Voltage Dip. This voltage dip occurs from 5-30 cycles after load is applied.
