The KD600B dielectric loss tester is a high-precision instrument used to automatically measure the dielectric loss tangent and capacitance of various high-voltage power equipment in power plants, substations, and other locations. Due to the use of frequency conversion technology, accurate measurement can be ensured under strong electric field interference.

KD600B dielectric loss tester is used for on-site anti-interference dielectric loss measurement or laboratory precision dielectric loss measurement. The instrument is an integrated structure with built-in dielectric bridge, variable frequency power supply, test transformer, and standard capacitor. By using frequency conversion anti-interference and Fourier transform digital filtering technology, automatic and intelligent measurement is achieved, and the measurement data is very stable under strong interference. The measurement results are displayed on a large LCD screen and come with a built-in micro printer for printing and output.
 

1. Equipped with CVT self-excited method test, connect once and measure the capacitance and tg δ of C1 and C2 simultaneously.

2. The maximum output voltage is 10kV, the maximum output current is 200mA, and the input current for high-voltage dielectric loss test is increased to 5A.

3. It has the function of reverse wiring low-voltage shielding, and can measure the dielectric loss of C11 without disconnecting the 10kV reverse wiring when the CVT bus is grounded.
