Influence of Supply Voltage Test Equipment ‘ISVT 01’ is used to measure and analyze the influence of supply voltage on energy meter. This test is described in various standards for energy meters such as IS 13779, IEC 62053 etc. As per CEI / IEC 62053-21, IS 13779 clause 12.7.2: The test shall be carried out under the following conditions: 1. Meter in operating condition. 2. Voltage and auxiliary circuits energized with reference voltage.
3. Without any current in the current circuits.Micro Controller based Sequencer
Variable Voltage Source.
SSR for Switching
Digital Voltmeter.
It is bench-top equipment housed in extruded aluminum channels and aluminum chassis; duly powder coated for better aesthetics.
Output Current : 1A AC.
Output voltage : 300V max.
Line regulation(200V to 250 V) : 0.2%
Load regulation(10-100% change) : 0.2%
Measurement accuracy(current) : 0.5%
Input Supply : AC 230V +/-10%, 50 Hz
The product is mostly offered as a standard issue, however we can customize it further if required.
The test kit is used to test the influence of supply dip on energy meter, after which the meter is tested for usual tests and the results are compared with previous one.
