How to test the electrical cables?

 Testing of Electrical cables(HV, MV, LV) : The following shall be the guidelines for the testing personnel during the inspection and testing of LV, MV and HV cables. 1.Phase identification test: Use safety grounding devices to discharge any trapped charges before connecting /disconnecting any test leads or other connections to/from the cable. Disconnect the cable under test from any electrical circuit. Connect the battery box, at one end of the cable :            - 0V to earth            - 4.5V to L1            - 9V to L2            - 13.5V to L3 Using a multimeter, check if at the other end of the cable, the voltages for each phase are correct according to drawings and specifications. 2.Shield continuity test: Use safety grounding devices to discharge any trapped charges before connecting /disconnecting any test leads or other connections to/from the cable.
