WIC1 g2 Self-Powered Protection Device

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
(#) = planned for Release 2.0.
