Dissipation current waveforms monitoring in LDPE sheet under water tree deterioration test (Part 2)

Deterioration with water tree phenomenon is the one of typical problem on the electrical insulation for the high-voltage class power cable. As the water tree which bridges cable insulation between inner and outer screen makes the insulation resistivity low, the conventional way, such as the leakage current measurement and so on are applicable as the… CONTINUE READING
