Single Phase Energy Meter Withstand Voltage Test Bench

Feature & Function

1. With special programmable power meter pressure instruments, using DDS source, PWM digital amplifier,

    10 bit A/D conversion, voltage ramp slow down function

2. With safety and protection facilities, interlock with high voltage output, also with warning lamp

3. Can do the test between “voltage/current to enclosure” and “voltage/current to auxiliary terminal”;

    also can do withstand voltage test between voltage and current

4. Separately set leakage current tester on every meter position; with independent withstand voltage cut,

    leakage current test and alarm for breakdown. The breakdown on any one meter position will not get

    influence on normal test of other positions.

5. When breakdown, audible and visible indication will come.

6. Can finish all various test at a time by switching the test function switch

7. With RS232 interface and can communication with computer
