High current test systems are used to test the thermal stability of equipment and components. The test system induces a current in the test object causing it to heat up. The system can perform the heat cycle testing for power cables type test and pre-qualification test according to IEC 60840, and IEC 62067 etc. Based on pre-qualification test needs, test system is divided into two parts: test ...

High-voltage dividers are used to measure voltages and decouple partial discharges in high-voltage test systems. Depending on the specific type, they are used to measure alternating voltage (AC), direct voltage (DC), lightning impulse voltage (LI), and switching impulse voltage (SI) systems. High-voltage dividers by PowerHV comply with the relevant IEC standards 60060, 61083, and 60052. The ...
