DC voltage test systems are mainly used to detect the performance of insulation materials under high voltage, long air gap DC discharge performance, insulation performance of large capacitance test objects like power cables, capacitors, generator sets and etc. Also they can measure leakage current of insulation materials and HV apparatuses, and DC HV testing for extra/ultra high voltage DC power transmission equipments.
