  • Sine high voltage supply

  • Integrated Safety System

  • PD Measurement Unit

  • Solfas Test Suite 2 (PD & HV tests included)

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.

3 Form Factors. From 12 to 100kV

From small to extra large test objects – we’ve got you covered.


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.

Take advantage of Solfas Test Suite 2

Since all GPD Models are shipped with Solfas Test Suite 2 you can take advantage of an easy-to-use interface to run your PD tests. Create and modify your required test sequences with the built-in test plan editor. Run the measurement and save your results in an easy-to-read PDF report.

Define your test voltage sequence

Set voltage steps, duration and slope to fit your custom or IEC standard test requirements.
