Portable Three Phase Field Meter Tester for energy meter with 100A clamp CT class 0.1
KE7303 Portable Three Phase On-site Electric Meter Tester
Accuracy : 0.1, Test method: clamp CT and terminal input. It's light and small, which is convenient for on-site test. And it can be used to test the error of three phase energy meters and field electrical parameters of power grid.
Features:
- Calibrate the error of all electricity energy meters, checking the constant of the energy meter
- Simultaneous checking of the primary meter and the secondary meter in the same loop, or simultaneously checking of the active power meter and reactive power meter inthe same loop
- Measure voltage, current, frequency, power, power factor and phase angle
- Simultaneous measure and display waveforms of three phase voltage and current
- Detectthe error change of the clamp automatically; ensure the accuracy stability ofthe clamp and the instrument in the long run.
- Measureratio of CT, VA burden of the metering loop from VT and CT secondary terminals.
- Allocate clamp of 20A, 100A, 500A, 1000A to directly measure the comprehensive error
- Measurethe 2nd – 51st harmonics of current and voltage
- Display vector diagram, judge the wiring right or wrong automatically
- Read the information of energy meter with barcode scanner (optional)
- Battery, test lead power or external power for choices
- Communicate with PC, download calibration data through USB flash disk, RS-232 or bluetooth
- Firmware can be upgraded through removed disk by users themselves
- Save and browse the testing data, data storage quantity is up to 1000 pieces.
