HV Coupling Capacitors
-
Our high-voltage coupling capacitors are a main component of our partial discharge test stations. They serve to decouple the partial discharge impulses and act as a voltage divider, the output voltage of which is matched to our partial discharge measuring devices (with integrated voltage measurement) and peak voltage measuring devices. These high-voltage components are also available separately in their various designs, sizes, capacities and voltage ranges.

TE-Metrology
-
HIGHVOLT Prüftechnik Dresden GmbH
The TE measurement complements the high voltage test and is part of the routine and type testing of numerous electrical devices. It is one of the most important non-destructive methods for detecting faults in electrical installations. The breakdown of an insulating material usually occurs at an internal weak point, which usually already shows a partial discharge activity in advance. For this reason, measuring partial discharges can help prevent costly damage. The TE measurement is thus used for quality testing and diagnosis in the factory as well as during on-site testing of cables, GIS, power transformers and transducers or rotating machinery and their components

Electrostatic Discharge Test
-
The electrostatic discharge test is designed to determine the ability of equipment to perform its intended function without permanent degradation of performance as a result of an air discharged electrostatic pulse. Electrostatic discharge is the result of an unbalanced electrical charge. Typically, it is created by insulator surfaces rubbing together or pulling apart. A transfer of electrostatic charge between bodies (materials, components, etc.) at different electrostatic potentials is caused by direct contact.
