scope:

This guide provides general guidelines toward the preparations of a functional specification of transmission fixed-series capacitor (FSC) banks using overvoltage protection based on three technologies:

- metal oxide varistors

- metal oxide varistors with a forced-triggered bypass gaps

- thyristor valve bypass

The commercial aspects of the specification for a particular project are outside the scope of this guide.

This guide does not apply comprehensively to thyristor-controlled series capacitors. A more complete reference is IEEE Std 1534™-2002.¹ The standard for fixed-series capacitors is IEEE Std 824™-2004.

¹ Information on references can be found in Clause 2.

Purpose

This guide presents technical clauses that may be used as the basis of a functional FSC specification. The annexes of this guide include related explanatory information. The annexes are cross referenced to the main part of the document.
