KE7302 Portable Three Phase Reference Standard Meter
Accuracy : 0.2, Test method: clamp CT and terminal input. It's light and small, which is convenient for on-site test, and can be used to test the error of three phase energy meters and field electrical parameters of power grid.
Features:
- Measure all kinds of meter, include single phase (1P2W) meter, three phase three wiremeter (3P3W), three phase four wire meter (3P4W) etc
- Measure the current with clamp CT and terminal two mode.
- Measure Vrms, Irms, phase angle, active power, reactive power, apparent power of three phase or single phase
- Measure total active power and total reactive power of three phase;
- Measure phase angle
- Measure frequency of power grid
- Display vector diagram
- Display waveform of voltage and current
- Analyze and display 2nd – 51st harmonic of voltage and current at real time
- Energy accumulating test (Dial test)
- Auto-check external wiring correct or not
- Test ratio of current transformer in low voltage circuit
- Wiring emulation, can simulate all kind of wirings on site without input voltage and current
- Realtime clock, accurate record testing time
- Store, browse and transfer measured data
- Real-time measured data by PC, and download calibration parameter
- Two kinds of power supply way: external AC power and voltage test lead power
