GDW305E Type Transformer No-load Loss Tester

It uses 240*64 matrix backlight LCD screen, and display 18 electric parameters of single-phase or three-phase voltage, such as voltage effective value, voltage average value, current, active power, power factor, frequency.

Multi screen menu operation, convenient operation, and automatic calculation of various parameters, such as P0, I0, Pkn, Pk75(120)℃, ekt, EK75℃, ZK.

Automatically correct voltage amplitude, waveform and temperature.

Press the button to set the voltage, current transformer ratio, directly display the primary measurement.

It can set the test date, transformer ex-factory number, and power-off latch.

It can measure power in the range of low power factor.

It is equipped with printing interface and serial RS232 interface, print format according to standard record format requirements (English).

Strong anti-interference performance; alarm function for over load; a reliable protection for overvoltage and over current; suitable for on-site verification environment.
