Voltage detectors and voltage testing systems
PASSION FOR PERFECTION
Safety is the top priority when working on medium-voltage systems. Our high-quality voltage detectors and test systems ensure reliable detection of the absence of voltage and support you in carrying out your work safely.

What are voltage detectors and test systems?
Voltage detectors and testing systems are indispensable safety instruments in the medium voltage range (1 kV to 52 kV). These high-precision measuring devices have been specially developed to reliably determine whether a system or system component is live or de-energized. According to safety regulations, it is essential to check that no voltage is present before carrying out any work on electrical installations and forms the basis for occupational safety in the energy technology sector.
Functionality and technology
Modern voltage testing systems work according to the principle of capacitive or resistive voltage measurement. They have highly sensitive sensors that can detect even the smallest voltages. The measurement results are validated several times by integrated verification mechanisms to rule out incorrect measurements.
Areas of use and applications
The systems are used in various areas of energy supply:
- In substations and switchgear
- For maintenance work on medium-voltage cables
- In energy distribution and transmission
- For the maintenance of transformer stations
- In the area of traction power supply
