Highlights & Challenges

The High Voltage Tester GHV1000-75-15 is used for testing medium voltage components such as power transformers, switchgear and cables.
We have developed and delivered 10 devices that perfectly meet customers’ specific requirements for output power and ambient temperature.

  • Voltage 0 .. 75kV AC

  • Current 200mA

  • Power 15kVA

  • robust, mobile and safe

Our Solution

The GHV1000-75-15 has been designed according to customer specifications for high output power and extended operating temperature contions.
The system consists of a control unit and a high voltage unit. This allows comfortable operation from a safe distance. The robust version on castors enables mobile use of the device in different locations. The setting of the current and voltage limits and the display of all measured values are made on a 7 ” TFT touch display.
The system is protected against short circuit, overcurrent, overvoltage and overtemperature and equipped with the safety features emergency stop, key switch, warning lamps and interlock.

Based on this GHV1000 approach we are able to design other solutions that fit different requirements.
