Variable Frequency Anti-Interference: Eliminates 50Hz interference, ensuring reliable data even under 200% strong electromagnetic interference.
Comprehensive Protection Functions: Includes ground protection, over-current protection, and electric shock protection with automatic high voltage cutoff.
CVT Self-Excited Test Capability: Measures C1 and C2 capacitance and dielectric loss without external attachments in a single test.
Integrated Design for Field Use: Built-in standard capacitor and HV power supply reduce field wiring and enhance portability.
Reverse Wiring LV Shielding: Enables reverse wiring dielectric loss measurement for C11 without dismantling wires under 220kV grounding.
Fast Automatic Measurement: Measurement process controlled by microprocessor completes in about 40 seconds with automatic digitization.
Wide Voltage and Frequency Range: Internal HV up to 10kV with test frequencies of 45, 50, 55, 60, and 65Hz.
