SCD0 - Electrical Substation Design

WGD9 – Substation Auxiliary System

Scope: This guide will consider the components of both the AC and DC substation auxiliary systems, and provide guidelines and recommendation for designing the appropriate systems for the substation under consideration. This guide includes the low voltage auxiliary systems from the source(s) to the distribution point(s). Reliability requirements and load characteristics are discussed and distribution methods are recommended.
