Cable Testing

Cable Testing

MV / HV CABLES TESTING BY VERY LOW FREQUENCY (VLF) TEST METHOD


Tests Carried Out At Very Low Frequency (VLF)

  • Insulation Resistance Measurement at recommended test voltage.
  • Polarization Index Measurement at recommended test voltage.
  • AC leakage current Measurement at rated voltage.
  • Capacitance Value Measurement at rated voltage.
  • Tan delta Value Measurement at Uo or 2Uo or 3Uo Voltage.

DC Hipot Testing

  • DC leakage current Measurement at rated voltage.

Cable PD And Fault Location

  • Partial Discharge Test for Cables Using VLF source.
