Switchgear remote control

  • increased demands for energy availability lead to rapid grid fault elimination requirements, isolating of the grid parts with failure and connecting a consumer to alternative power lines in the overhead medium voltage grid
  • remotely controlled disconnecting devices, besides having a function of automated disconnecting switch control, also enable measurement and registration of electrical quantities that can be interesting for later grid analysis
  • nonconventional current and voltage sensors SS-30 and NS-20 are used for measurement
  • various fault indicators, for instance IK-20S, are used depending on the type of grid and type of disconnecting switch (grounded or insulated)
