  High Voltage Laboratory (HVL)  
  The High Voltage Laboratory (HVL), has two shielded buildings, the High Voltage building is 40x25x25 mxmxm sized and the Medium Voltage building is 29x13x12 mxmxm sized and a climatic chamber 5,5x3x3 mxmxm sized.  
   
  High voltage building
  In the High Voltage building there is an industrial frequency generator 1 MV (50 Hz/60 Hz) and a lightning impulses generator 2,4 MV (switching impulse2,0 MV up to 1,3 MV).

Technical characteristics
  • Industrial frequency system: 1 MV/ 2 x 500 kV, 1 A/ 2A
  • Resonant system: (20 Hz-300 Hz): 680 kV, 3 A
  • Lighting voltage impulses system 1,2/50:2,4 MV, 120 kJ
  • Switching impulses system: 250/2500: 1,3 MV, 120 kJ
  • PD and RIV measurements up to 400 kV

  Medium voltage measurement
  In the High Voltage building there is a 1 MV industrial frequency generator (50 Hz/60 Hz) and a lightning voltage impulses generator 2,4 MV (switching impulse up to 1,3 MV), measurement of ratio and phase displacement errors on voltage and current instruments transformers, partial discharges measurement in Faraday cage and power transformers testing including measurement of no-load losses, short-circuit impedance and load losses, voltage ratio, windings resistance, induced voltage test, temperature-rise test...

Technical characteristics
  • Industrial frequency system: 150 kV, 1 A
  • Lightning impulses system 1,2/50; 400 kV, 10 kJ
  • Faraday cage: 4x 3 x 2,5 mxmxm

  Climatic chamber
  In the climatic chamber performance tests are conducted at extreme temperatures, reproducing adverse atmospheric conditions between -40o and +60o C.

Technical characteristics:
  • Dimensions: 5,5x3x3 mxmxm
  • Maximum temperature: + 60º C
  • Minimum temperature: - 40º C
  • Refrigeration capacity: 30,5 kW
