Refresher training for grid operators 1 to 30 kV

Wiederholungsausbildung Schaltbefähigung

Target audience:

This training is for operating engineers, master electrician, electrical engineers, employees of power supply companies, municipal utulities, maintenance work and service work on transformer stations who shall become switching operator.

Requirements for training:

  • electrically skilled person pursuant to BGV A3
  • health wise and personnel-wise qualified
  • proof of first-aid training
  • proof of basic a training

Duration: 1 Day

Theory according to BGV A1, BGV A3 and VDE-0105 you learn the 5 safety rules which are basing on practical switching programs to make and secure the volt-free condition, including to set under voltage after completion of work.


  • requirements for operators
  • duties of the operator
  • legal basics
  • personal protection, installations and PPE
  • grid structures (radial system, ring system, meshed system)
  • utilities e.g. circuit breaker, earth fault breaker, power switch, fuses, transformers, transducer
  • switching assessment, switching commands, realisation of switch actions
  • definitions e.g. written approval, permission of disposal
  • design regulations, construction, station supplies
  • first aid after electrical accidents
  • switching of transformers with 0.4 kV winding
  • switching of cables and overhead lines up to 30 kV
  • approve a complete transformer station
  • illustration of clear switching commands to avaoid faulty circuits
  • application of form, work permission and approval for work in installations >1 kV
  • verification in transformer stations
  • compliance with safety distance to high-voltage components
  • switching operations according to overview-, grid- and circuit-diagrams
  • avoiding of faulty circuits
  • behaviour during disturbances
  • causes which could lead to faulty circuit
  • assessment of installation conditions
  • fire prevention
  • references


  • written test
  • certification counts also as repeat training and yearly instruction

The training can be adapted according to your requirements, specification, grid plan, etc.

Switching practice:
We offer to the normal training an additional practice day in the direct connection to deepen the practical training.

Because of a great demand, we extended our training facility with many switching installations which can be real operated.
