On-Site Acceptance Voltage Test for 220 kV Long-Distance Large-Cross-Section XLPE Power Cable

To ensure safety and reliability of power cables after putting into operation,series resonance test scheme and series parallel resonance test of 220 kV long-distance large-cross-section XLPE power cable were compared.And the capacity rise phenomenon of 220 kV power cable with a length of 14.45 km was simulated.Results showed that for on-site Acceptance voltage test of 220 kV long-distance large-cross-section XLPE power cable,series parallel resonance test was suitable,and the temperature rise of each test equipment was controllable and within the allowable range,which could meet the voltage test requirements of 220 kV long-distance power cable.
