Reliable safety through mains and machine protection tests

Protective device testing

Protective devices are an essential part of energy supply systems (e.g. CHP) or other grid feed-in points. These protective devices have to trigger quickly and selectively in the event of errors and faults in order to ensure safe and therefore economical operation.

In addition to the required regular protective device tests according to the guidelines of VDE 0105 and DGUV regulation 3, the protective devices must also be comprehensively tested after each modification of an installation.

With the most modern measuring equipment, we competently and reliably test the most diverse protective devices (electromechanical, electronic and digital protective relays) of all leading manufacturers in low- and medium-voltage systems. Primarily, the function, tripping time and measuring accuracy of the protective devices are checked and recorded.
