Power testing laboratory

Laboratorio de ensayos de Potencia

Test laboratory that makes it possible to carry out tests with a power limit of 300 MVA, 1 s, on electrical equipment intended to be connected to the electrical grid.

This laboratory is connected to the 220 kV high voltage grid and is capable of obtaining voltages of between 2.7 kV and 39 kV for testing medium voltage equipment, and for voltages below 1 kV and low voltage.

Description

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.

Aimed at:

  • End customers such as engineering firms and installers.
  • Manufacturers of electrical equipment.
  • Electrical companies.
