High Voltage DC Test Set is used to check the quality of di-electric strength of the insulation in cable, capacitors, transformers and many electrical components. High Voltage DC Test Set is used to identify the deterioration in the insulation as early as possible to take corrective measures. The DC Test Set ensures fully protected operation with safety interlocks. The DC Test Set functions in selectable current ranges for precise leakage current readings. The DC Test Set operates on a power supply rate of 230 V AC, +10% at a frequency rate of 50Hz, in single phase mode of operation. High Voltage DC Test Set is facilitated with built in auto discharge in case of mains power failure or equipment switch off.
