Power testing laboratory

Zamudio 2 Location

This infrastructure makes it possible to carry out different types of tests for which a certain amount of power is required:

• Low voltage equipment (fuses, switches, panels, busbars and circuit breakers, among others):

1. short-circuit tests up to 150 kA 1 s
2. breaking capacity tests: 240 V, 400 V, 500 V — 120 kA 690 V, 800 V — 80 kA
3. opening and closing tests
4. internal arc tests

• Medium/high voltage equipment:

1. ampacity test
2. opening and closing tests with inductive and capacitive currents (voltages up to 38.5 kV and currents up to 800 A)
3. internal arc test: up to 300 MVA by adjusting the voltage
4. special resistance heating and capacitor banks, among others
5. short-circuit of transformers up to 10 MVA

The facility also has:

• Control room: with capacity for eight people, with three screens, equipment to control how the test is carried out and display the measurements.
• Two testing rooms; one of which is of 70 m²; and the other is an internal arc test room of approximately 25 m².

All measurements carried out in the power laboratory are isolated from the recording equipment by means of optical fibre to avoid interference and provide insulation.
