Powerhv products

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 systems are available for both indoor and outdoor use.

The impulse current shunts are designed for impulse current measurements on low inductive test objects. They are primarily used for impulse current measurements on power transformers (IEC 60076-3). Yet they can also be used for impulse current measurements with wave shapes 4/10 µs, 1/20 µs, and 30/80 µs on metal-oxide surge arresters according to IEC 62475. They are available with a rated resistance ranging from 0.1 ohms to 10 ohms and a rated current ranging from 100,000 A to 50 A.

PowerHV offers the high-precision measuring bridge and standard capacitor for the C & tan delta measuring.
