Electrical tests

Eurailtest performs tests to qualify the performance of electrical equipment and insulators.

Electrical testing in the laboratory

Qualifying the performance of electrical equipment and simulating incidents encountered in revenue service

Tests objectives :

  • Check the functioning of low power and high power products according to a standard or a technical specification
  • Check the conformity of a product or a series
  • Check that equipment functions properly
  • Assess life potential of a component
  • Conduct tests as required by the customer. Examples:
    – Overheating of electrical components
    – Behaviour at high voltage (120 kV – 50 Hz) and with strong direct or alternating current (100 ms window, 40 kA at 1,800 V DC)
    – Performance of electrical equipment: Rheostats, static converters, etc.
    – Short-circuit tests on specific equipment (e.g. transformers)
    – Evaluation of switchgear performance: Contactors, circuit breakers, switches, etc.
    – Measurement of harmonic currents

Tests facilities :

  • DC power system: 1.5 kV/3 kV DC – 5 MVA
  • Single-phase power system: 50Hz, 8 to 30 kV AC – 12 MVA
  • Three-phase power system: 50Hz, 0 to 2 kV AC – 1.5 MVA
  • High-intensity power system: 0 to 20 kA, 10 V DC
  • High-voltage resistance equipment: 0 to 120 kV AC – 50 Hz
  • Climatic test chamber (40°C)
  • Switchable outdoor OCL: 25 kV/50 Hz, 1.5 kV, 3 kV
  • Digital data acquisition and processing system
  • Voltage and current sensors
  • Temperature measurement with or without electric potentialue

Testing norms :

According to the customer’s technical specifications

Electrical withstand tests

Qualify the performance of electrical insulators and assemblies

Tests objectives :

• Assess voltage withstand of materials or
finished products
• Identify the creepage distance of an
electrical assembly or the breakdown
voltage of a component

Tests facilities :

HV generator 20 KVAC – 70 KVDC

Testing norms :

EN 50124-

EN 60060-

EN 60077-
