• Secondary Equipment Testing

Power Generation to the User

Operators of electrical equipment have to test the protection devices as part of the periodical inspections to verify the correct settings and the functionality.

These tests require trained personnel and different test equipment for the particular equipment. For many operators, it is not possible to fully load the test equipment and the personnel. Our protection engineers know the protection relays of all renown manufacturers and are equipped with modern test equipment from Omicron and Megger. We support you with the testing of the secondary equipment and log the measured tripping times and the injected values for your records. You do not have to care about test equipment or training of your personnel. Of course we also test all other kinds of secondary equipment like synchronisation relays, transducers for all kinds of electrical values and energy meters.
