Today’s LiveWire Spotlight article addresses the latest version of PRC-005-2 Draft 7 – the latest version of NERC’s updated Protection System maintenance Standard – consolidating requirements from PRC-005-1, PRC-008-0, PRC-011-0, and PRC-017-0. A full re-review is required even though the 2/3 threshold was easily achieved in the prior ballot due to an adjustment made in response to an IEEE concern that battery capacity testing must be mandatory.

The updated versions of PRC-005-2 and its support documentation have been posted for a 30 day review period and concurrent ballot. Industry stakeholders may return feedback to the project team until June 27, 2012.
