Overview
The “Breaker arcing current” element calculates an estimate of the per-phase wear on the breaker contacts by measuring and integrating the current squared passing through the breaker contacts as an arc.
For more detailed information on “Breaker arcing current” element, refer to GE, Universal Relay (UR) family of products, Version 8.0x manuals.
