Special equipment

Components and systems for neutral-point connection

Medium-voltage systems in Europe are largely operated as resonant-earthed systems. SGB offers a complete range of products for the necessary neutral-point connection:

  • Arc suppression coils
  • Fixed coils, off-circuit variable tapped coils as well as coils variable under load. The variable coils can be operated with the fitted electronic regulators and have an automatic mode.
  • Neutral electromagnetic couplers
  • Earthing transformers
  • Earth fault combinations consisting of neutral electromagnetic couplers and arc suppression coils.

 
In special cases the use of oil-immersed equipment is restricted due to environmental protection considerations. In these cases we use special synthetic or organic esters (e.g. Midel 7131).
