With the test facilities in our high voltage testing laboratory all dielectric and partial discharge tests for medium voltage equipment can be carried out. For sensitive partial discharge tests a special test chamber is available with a background level < 1 pC.
In order to offer on-site testing the high-voltage laboratory has mobile test equipment.
The high-voltage testing laboratory performs the following tests:
Standard lightning impulse voltage tests
• Up to 760 kV
Power-frequency voltage tests
• Stationary up to 260 kV
• Mobile up to 160 kV
Partial discharge tests
• Stationary up to 150 kV
• Mobile up to 160 kV
Degree of protection tests
Tests on auxiliary and control circuits
