Primary Equipment Testing
Power Generation to the User
During commissioning or periodical inspections, we test the installed primary equipment.
Examples of Services and Prices for Primary Testing
Testing of three current transformers with one core each. Basis for the fix price offer is the available documentation of the protection cabinet and good accessibility of the current transformers.
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.
- Isolation test
- Ratio and phase angle
- Winding resistance
- CT Polarity
- CT excitation and saturation
- Burden impedance
- Estimated Time for the tests approx. 3h
Testing of three single phase voltage transformers with one core each. Basis for the fix price offer is the available documentation of the protection cabinet and good accessibility of the voltage transformers.
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.
