High voltage testing

In this laboratory, the following tests on electrical power transmission equipment and railway systems or components to determine the operational strength are carried out:

• Lightning and switching impulse voltage
• Alternating voltage
• Direct-current voltage
• Surge current

These tests can be carried out according to international or European standards or according to customer specific requirements.

The following test methods are also available for diagnostic purposes:

• Loss factor measurement
• Insulation resistance measurement
• Partial discharge measurement

Material dielectric testing as characterisation are also provided:

• Investigation of dielectric breakdown strength for solid or liquid dielectric materials
• Investigation of dielectric permittivity and the dielectric losses (tan D) for solid insulating materials (5 µHz up to 50 MHz)
• Investigation of electrical volumetric or surface resistivity (conductivity) of solid insulating materials
• Investigation of the ageing behavior of solid or liquid dielectric materials.
