Electric Meter
YC1893D three phase electric energy meter test system can measure three phase mechanical meter, electric mechanical meter and electronic meter by the way of automatic, semi-automatic or Manual. The material is aluminum alloy, light and strong, prevent corrosion
Function:
- Starting test and creeping test
- Measuring the different constant meters synchronously.
- With the protect function of overload, short voltage circuit and open current circuit.
- The testing software with friendly Windows 2000 and XP interface, include functional module of all kinds of modern energy meter needed, to reality error test, harmonic test, demand test, influence test.
- The stored testing data can be transferred to multi-format for other program using
Character:
- Meter under testing: 3P4W, 3P3W, 1P2W
- Testing mode: active power, reactive power, cross connection reactive power
- Installing the ICT in each meter position to test three-phase meters with closed links between the current and voltage measuring circuits (I-P links) (optional)
- Neutral current test (optional)
- Installing RS232, Ethernet communication port in each meter position, to reality the automatic calibrate of electronic meter (optional)
