New installation and commissioning

Full installation of Gas Insulated Switchgears (GIS), Air Insulated Switchgears (AIS) and Generator Circuit Breakers (GCB) from various manufacturers with a well-coordinated installation team with in-depth technical and product knowledge.

Execution / installation processes and the quality checks

  • Primary and secondary installation
  • SF6/G3 gas handling (DILO device, gas analyzer)
  • Primary/secondary testing (various devices)
  • Cold commissioning
  • High voltage test support (UHF measurement with spectrum analyzer)

Planning and organization of site infrastructure

  • Creation and implementation of safety concepts
  • Lifting equipment, lifting platforms, tools
  • Scaffolding, containers (office, tools, crew, sanitary)
  • Waste concept (separation and disposal)

Condition check, monitoring and analyses

In today’s energy security environment, we offer a manufacturer-independent and time-saving condition control of gas-insulated switchgear, outdoor switchgear, dead-tank circuit breakers and generator circuit breakers. The method of non-invasive condition control reduces shutdown times to a minimum.

  • Visual control
  • Gas quality measurement (gas pressure, purity, dew point)
  • Densimeter check
  • Contact resistance measurement
  • Timing test of circuit breakers, disconnectors, earthing- and high speed earthing switch (conventional or with Rogowski coils)
  • Thermography, detection of hotspots by infrared camera
  • Analysis (data evaluation and solution recommendation)

Dynamic resistance measurement

Regular measurements of the static and dynamic contact resistance allow precise statements to be made about the condition of the entire contact system. Necessary maintenance work can thus be detected at an early stage and downtimes prevented.


  • Renewal of control and protection systems
  • Adaptation of control, operating and signalling systems
  • Planning and recommendation of control and protection concepts
  • Preparation of detailed drawings of secondary cabinets

Site Management

  • Project preparation
  • EHS (Environment, Health und Safety) responsibility and implementation
  • Site management and site organization
  • Provision of infrastructure (office, containers, sanitary containers, waste disposal concept)
  • Coordination with our client and third party suppliers
  • Regular construction progress reports, cost control and final report
