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.
TECHNICAL DETAILS
Input voltage: 415 V AC, 3 phase 50 Hz
All the three tests can be carried out as per clause 12.7, 2.1 of IS:13779.
- 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.
- Compact Design.
TECHNICAL DETAILS
Input voltage: 415 V AC, 3 phase 50 Hz
All the three tests can be carried out as per clause 12.7, 2.1 of IS:13779.
- Voltage interruptions of Vref = 100% (1s, 3 Nos)
- Voltage interruptions of Vref = 100% (20 ms, 3 Nos)
- Voltage dips of Vref = 50% (1Min,1 No.)
