HVA Report M74-L2: Device Under Test Is Cable

This report summarizes test results for a 10m long, 15kV rated cable (M74-L2) located in Puerto Bolívar, Machala. The cable passed a very low frequency diagnostic test up to 24kV without breakdown or failure over 15 minutes. Measurements showed capacitance decreased slightly with higher voltages while resistance remained over 20GOhm. The report concludes the cable can be energized according to IEC 60502-2 standards.

Comments The VLF electrical testing analysis on the cable M74 on phase L2 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.
