Dielectric testing at medium voltage level

Damstra laboratory has a long history with validation of Medium Voltage switchgear and accessories.  The dielectric testing lab is equipped with a High Voltage test generator for impulse voltage testing up to 400kV. For partial discharge measurement both a 3-phase as well as a 1-phase voltage source is available. For measuring the behavior of solid insulation very accurate testing in the order of one pico-Coulomb can be performed.

Also mechanical behavior of medium voltage switchgear can be tested and validated against the standard. By using sophisticated measurement equipment the various specifications of a mechanisms can be captured in graphs.
