CT Type

The second generation of the WIC1 family is a series of self-powered / CT powered protection relays, designed for harshest environments. The new WIC1 relay family does not need auxiliary energy since they are CT powered. A dual/redundant powered variant enables communication options in addition to the power outage safe protection core. The main applications are:

  • Protection of Ring Main Units for Power Distribution
  • Protection of Step-Up Transformers e.g. for Wind and Solar Power
  • Protection of Feeders
  • Current based protection when auxiliary power is not available or too costly
  • Backup Protection – available in absence of auxiliary power
  • Disaster recovery – Blackstart capability (after short or long lasting) outages – provides reliable protection, when all other protection relays fail because of drained battery rooms
