HVA Report M75-L3: Device Under Test Is Cable

The report summarizes a VLF test on a 10m long, 15kV rated XLPE insulated cable. The test subjected the cable to voltages from 0.5kV to 24kVrms over periods from 1 to 15 minutes, measuring current, capacitance and resistance at each step. No breakdown or failure occurred and the cable passed the test according to IEC 60502-2 standards, allowing it to be energized.

Comments The VLF electrical testing analysis on the cable M75 on phase L3 indicates
thatwith an injection voltage of 24 kVrms (34 kV peak) for 15 minutes,
according to the IEC 60502-2 (2014) standards, there was no arc discharge,
passing thetest. The cable can be energized.
