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 HIGHVOLT comply with the relevant IEC standards. The systems are available for both indoor and outdoor use.
