HVTC

High Voltage Test Chambers

Ready-to-use test chambers for easy and safe partial discharge testing

HVTC

The High Voltage Test Chamber HVTC is designed for PD testing on e. g. transformers, semiconducters, and micro samples. Depending on the built-in HV transformer, testing up to 20 kVrms is possible. The test chamber provides sufficient space to test samples up to a maximum size of 500x500x400 mm³. The main components of this system are: a high voltage transformer, a regulating transformer, a coupling capacitor of 1 nF, an automatic grounding system, a security interlock loop, and multiple warning lamps.

Beside solutions for the standard range of applications we provide customized solutions for special test applications. In the past we designed PD measurement test benches for special tasks such as PD test cabinets for insulation foils of solar panels or PD test cabinets for heating pumps and small motors, e. g.

High Voltage Test Chambers

 

Partial discharge occurring in insulating materials can cause long-term damage of the material when exposed to high-voltage stresses. Partial discharge testing can detect voids or imperfections in insulators and, hence, helps to prevent overheating and breakdown under normal operating conditions. Since PD signals are susceptible to electronic and RF noise, corona-free and properly isolated test chambers are of high importance for such tests. Those chambers can be used in development, production, and quality assurance for nondestructive isolation and quality tests of electric components such as

  • Electronic Components
  • Insulation materials
  • Capacitors
  • Transformers
  • Switches
  • Arrestors
  • Cable and wire samples
  • Insulated-gate bipolar transistor (IGBT)
  • Semi conductors
  • Micro samples

Power Diagnostix' high voltage test chambers HVTC are suitable for PD tests according to international standards. Depending on the built-in HV transformer, testing up to 20 kVrms is possible. The test chambers provide sufficient space to test samples up to a maximum size of 500x500x400 mm³. If high voltages are required, open test areas can be designed and offered. Additionally Power Diagnostix offers Moveable Protective Grating for high voltage test areas.
