CE Certification
Usage Characteristics and Performance
The Automatic Transformer Tan Delta Test Set features an integrated structure, incorporating a built-in dielectric loss bridge, variable frequency power supply, test transformer, and standard capacitor. Utilizing frequency conversion anti-interference technology and Fourier transform digital filtering, it performs fully automatic and intelligent measurements. The measured data remain highly stable even in strong interference environments. Results are displayed on a large LCD screen and can be printed using a built-in micro printer.
The instrument also includes an insulation resistance measurement function. The connection mode for insulation resistance measurement is identical to that used for dielectric loss testing, allowing both parameters to be measured in a single setup. When this additional function is employed, it reduces the amount of equipment required on-site and minimizes test workload.
