1Multi functional insulation dielectric loss testerUsage characteristics and performance

High voltage dielectric losstest deviceUsed 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. Adopting frequency conversion anti-interference and Fourier transform digital filtering technology, the measurement is fully automated and intelligent, 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.
