Full Description

Scope

The scope of the guide includes the grounding practices presently used and the practices that were not previously reported. Specifically, the issue of the grounding of cases of electronic transducers is addressed.

Purpose

This guide provides information on the grounding of the following: - Secondary circuits of electromagnetic CT and VT circuits - Cases of relays, CTs, and VTs - Secondary circuits of optoelectronic CTs and VTs The primary emphases of this guide are personnel safety and proper performance of relays at electric power frequencies.

Abstract

Revision Standard - Superseded. The practices described in this guide apply to all instrument transformers, including capacitive voltage transformers (VTs) and linear couplers, irrespective of primary voltage or whether the primary windings are connected to, or are in, power circuits or are connected in the secondary circuits of other transformers as auxiliary current transformers (CTs) or VTs. This guide does not discuss the grounding of some applications. For example, grounding of gas insulated substations and metal clad switchgear is not discussed in this guide; the reader will find these topics addressed in IEEE Std 242. The grounding of circuits of core-balance CTs is also not discussed in this guide. The reader can also find this information in IEEE Std 242. Another issue that is not discussed in this guide is the practice of using separate safety and control grounds. For discussion on this topic, the reader is directed to IEEE Std 665. See more
