Welcome to HIGHVOLT!

The global demand for electricity is rising, and with it the need for power generation systems. Systems that must work dependably, maintaining a stable electrical supply for industry and private households. Our high-voltage testing and measuring technologies keep equipment such as transformers or switchgear reliably up and running, avoiding any downtime or malfunctions. By this means, we play an active part in the global energy transition. Thanks to our innovative products and solutions, we always accomplish our mission: to maximise electrical grid availability. A task that truly has high potential!

 

As a member of the Reinhausen group, we at HIGHVOLT can always draw upon their expertise and services in the field of producing, distributing and transmitting electrical energy.

Selected Producs

WRV T

Withstand voltage tests on AC and DC XLPE cables can be performed using the AC test system with variable frequency (WRV T) in the factory or once laid on-site. The test system operates in a frequency range from 10 Hz to 300 Hz and complies with the requirements according to IEC 60840 and IEC 62067....

IP

Impulse voltage test systems (IP) are used for impulse voltage testing of transformers, cables, gas-insulated switchgears (GIS), arresters, and other high-voltage devices. The test systems generate lightning impulse voltage (LI, 1.2/50 µs), chopping lightning impulse voltages (LIC, front time 1.2...

HCTS

High current test systems are used to test the thermal stability of equipment such as cables. The test system induces a current in the test object causing it to heat up. Therefore, the test object is designed as a shorted circuit. The high current test system measures the temperature of the test...
