Sudden power outage – causes and tips

Possible reasons for a sudden power outage:

  • Self-consumption is too high.
  • Damaged fuses or a circuit breaker has tripped.
  • A power cable has been disconnected because of construction work.
  • A short circuit has occurred at a transformer station or substation.
  • A high-voltage cable has been damaged. 
  • There is major disruption in Switzerland or Europe.

What to do during a power outage:

  • Switch off stoves, irons, drills, circular saws, vacuum cleaners, modems, sound systems, PCs, TVs, etc., otherwise these devices will automatically switch on when the electricity is turned back on.
  • Lamps can remain switched on and should work again safely when the power is turned back on.
  • Freezers or fridges only need to be emptied once the power has been off for approx. 6 hours. Do not open them, as this will allow the cold to escape.
  • A landline will work for a maximum of four hours without electricity. Devices that connect to the mains power supply will not work.
  • Tell older residents and children about the power outage.
