What is partial discharge?

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.

Ho 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.

A system for any field of application

GPD-Compact 6kV

With integrated test cabin for smaller test objects like optocouplers, power semiconductors, switch gear or cables up to a size of xxx mm in width and xxx mm in height

GPD-HV 12-25kV

With integrated high voltage unit for medium sized test objects.

GPD-HV 50-100kV

With external high voltage unit for large test objects.

Low distortion electronic AC source

The innovative and efficient frequency converter technique allows frequences between 50-60 Hz. A sinusoidal output voltage with a low harmonic ( accuracy 2.5%) is generated. The voltage can be regulated  precisely. The remote control via PC allows safe testing from the control room.
