The input supply is expected to change time to time. So the voltage dip and interruption test set is subjected on energy meter. The equipment consist of pre-set timer to supply voltage 100% or more or less as per requirement of the test for duration required by the test. The supply is also cut off and re-stored again at a pre-set timing as per the test requirement.
All the three test in one test set-up
Highly reliable electronic control circuit.
Variable reference voltage for different ranges of Energy Meters.
Set reference voltage induction on digital voltmeter for each phase
Suitable for single phase and three phase energy meters.
