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.
Examples of Services and Prices for Secondary Testing
Testing of two line differential protection relays which are connected via a fibre optical cable. Condition for the fixed price offer is that the distance between the two relays is below 1km and the client provides one person to assist the test engineer.
The fix price includes time for preparation and documentation on INP standard test protocols, 2 hours for site specific training and introduction, expenses and accommodation if required as well as the journey up to 50km from CH-5400 Baden.
