MAIN FEATURES

Design

Modular designed to meet every need of our customers, from a pure basic setup to lean integration.

Safety advantage

Excellent protection from electrical hazards due to complete encapsulation and no use of harmful products

Health & environment

Oil free, non inflammable, no ground water pollution as well as a simple end of life treatment, available with Pure Air Technology.

Low demand of Space

Due to encapsulated setup and use of gas insulation, unbeatable low footprint of occupied space.

Long Life-time
Low maintenance

Test equipment has a proven life-time for over 30 years and requires low maintenance. We offer full service solutions to keep the downtime at a minimum, thanks to remote troubleshooting and service on site.

Excellent PD Sensitivity

PD sensitivity close to theoretical limits, e.g. < 0, 5 pC at 1’000 kV can be reached.

Main applications of the High Voltage Test Systems

Trench test systems are versatile and can be adapted to a wide range of applications.

Test bushings AC and DC
We manufacture AC and DC test bushings up to 1, We can also supply GIS terminations for cables, 000 kV.
Powerful system
Possibility of connecting several high-voltage transformers in parallel to increase the available power or the duty cycle, even several years after installation.
GIS and AIS interfaces
Trench test systems can have direct connection to GIS . To test AIS-type objects the test systems can be equipped with bushing available by Trench and HSP.
Tests on cable accessories
Test system with multiple outputs for testing HV and EHV cable accessories at the same time. Each output is equipped with a HV disconnector, which allows one or more test objects to be removed from the test circuit.
Pure Air technology available
test SF6 free products with SF6 free test equipment.
AC & DC test systems
A single test system to perform AC and DC tests on a test object., Example of a compact 325 kVAC / 360 kVDC system.
