9 High Voltage Testing 9.0 High Voltage Testing Procedure Electrical equipment must be capable of withstanding overvoltages during operation. Thus by suitable testing procedure we must ensure that this is done. High voltage testing can be broadly classified into testing of insulating materials (samples...
The ac voltage can be applied during use of the able or during a period corresponding to that during which the cable is used. Alternative time periods, continuous or at intervals are specified.

Testing is done to ensure that the equipment is intact and to provide a level of confidence that the insulation will continue to function reliably until the next significant power outage.Even if some of the overvoltage test currents are lower than the generally regarded lethal values,...
