Commissioning test

Commissioning tests for substations and medium- and high-voltage installations

Safe connection to the grid – tested in accordance with standards, fully documented. We test your switchgear, transformers, protection and telecontrol systems prior to commissioning and lay the foundations for safe, reliable and selective grid operation.

From testing to handover

What happens at the end of the commissioning test

From partial discharge measurements right through to end-to-end testing at the control centre, you will receive comprehensive evidence of your system’s fault-free condition and operational readiness – in accordance with applicable standards and network operator specifications. Where the measurement results suggest it, we optimise settings and parameterisation for continuous operation. Finally, we train your operating staff and hand over a tested, operational system to you.

Examination requirements

What we check before commencing operations

From partial discharge testing to functional testing of the entire system – we provide verifiable evidence of every test and document the results against the permissible limit and reference values.

Detect insulation faults before they lead to a failure.

Using partial discharge testing, we reliably assess the insulation condition of your switchgear and busbars. Even the smallest insulation faults are detected, and potential sources of discharge on busbars, insulators and connection points are precisely localised. By comparing the measurement results with permissible limit and reference values, you are provided with a robust basis for assessing the condition of the insulation prior to commissioning.

Everything under one roof

Your commissioning test, all under one roof

From partial discharge testing to telecontrol testing, we provide a one-stop service for all testing requirements for your medium- and high-voltage installations – carried out in accordance with standards and fully documented. Please contact us for a no-obligation quote for the commissioning test of your substation.

Good to know

Frequently asked questions about the commissioning of substations

The duration depends on the size, voltage level and complexity of the installation and typically ranges from a few days to several weeks. The key factors are the scope of the protection and telecontrol tests, as well as the number of fields and pieces of equipment. Following a review of your plant documentation, we will draw up a binding timetable and schedule that fits in with your project timeline.
