Electrical Testing of Switchgears and Assemblies of Switchgear and Controlgear

IMA Dresden – your partner for development and type tests with a comprehensive service portfolio starting with short-circuit tests over operating behavior up to insulating behavior. Across all industries sectors, we cover the test areas of renewable energies, automotive/ e-mobility, railway applications and beyond.

High Performance Test Field

The modern high performance test field provides versatile test applications up to 25,000A, such as switching capacity, operating behavior, electrical lifetime and short-circuiting.

Typical device groups:

  • Circuit breaker, switch-disconnector and transfer switching equipment
  • Fuse-combination units
  • Relays, contactors and motor starter
  • Terminal blocks and connections
  • Heavy connectors
  • High current components automotive
  • Switchgear and controlgear assemblies

Lifetime Testing

Flexible applicable test fields (16 specimen/test field) for electrical, pneumatic and hand-operated switching devices are available for testing of electrical and mechanical lifetime, operating behavior as well as making and breaking capacity.

Typical device groups:

  • Control circuit devices, proximity switches, alarm switches
  • Relays, motor starter
  • Fuse-combination units
  • Contactors

Heating and Continuous Current Tests

Automated test field with wide-ranging test possibilities for switchgears and assemblies of switchgear and controlgear:

Continuous data acquisition of:

  • Temperature
  • Current
  • Voltage (Determination of partial and total power loss)
  • Cyclical current control (intervals/cycles)
  • Superimposition with climate testing

Typical tests:

  • Heating and continuous current testing
  • Overload testing of devices with fuses and thermal release
  • Determination of derating curves (current can get controlled up to target temperature, for example at connection area)

Insulation Testing

  • power-frequency withstand voltage up to 5kV AC
  • impuls withstand voltage up to 24kV; 1.2μs/50μs (36 Joule)

Further Testing Possibilities

  • Creepage distances and clearances
  • Mechanical test rigs force-distance
  • Strength operating units / misapplication forces
  • Mechanical strength of contact points
  • Bending tests
  • Tensile tests
  • Protection type testing (IP-code)/ touch protection
  • Climatic tests (temperature/humidity), combinable with other tests
  • Vibration/shock testing
  • Glow-wire testing/flammability
