Partial Discharge & High Voltage Test
All-in-one Partial Discharge Test System according to IEC602070, IEC60664-1 and IEC61730-2
What are partial discharges?
Partial discharges are a result of local electrical stress concentrations in the insulation or on the surface of the insulation which lead to electron movements.
How do they occur?
Partial discharge can be described as small electrical sparks that occur in windings whenever there are small air gaps or voids in or around the insulation. Once sparking occurs, the windings start to deteriorate. The larger the void in insulation, the larger the possible discharge resulting in possible machine failure.
Compact 19” rack with integrated high voltage unit and test cabin for smaller test objects like optocouplers, power semiconductors or transformers. For test voltages up to 12kV.
With integrated high voltage unit for test voltages up to 25kV.
With external high voltage unit for test voltages up to 100kV.
Low distortion electronic AC source
The energy-efficient and low-interference electronic AC power source enables precise and fast regulation of the output voltage during partial discharge measurement. The rate of voltage rise and the output frequency are adjustable. PD are measured with a high precision instrument. The remote control via PC allows testing from a safe distance.
