Profile:

KDJF-5kVA/50kV is an integrated hipot test system with SF6-insulated transformer and digital PD detector. It features low background noise, high voltage stability and comprehensive protection, ensuring reliable and accurate high-voltage testing.

Features:

  • SF6-insulated test transformer with double-layer sealing, service life ≥15 years
  • Low partial discharge level (≤3pC at 80% rated voltage) and waveform distortion ≤5%
  • Integrated isolation filter eliminates power supply interference (background PD ≤5pC)
  • Digital PD detector with LCD display, supporting ellipse/linear/sine wave modes
  • Multiple protections: zero-position start, overcurrent/overvoltage, emergency stop and door interlock
  • Continuously adjustable voltage (0~50kV) with 1.0% voltage accuracy
  • Coupling capacitor with built-in voltage divider (1000:1 ratio, 0.5 class accuracy)
