The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition.IEC TS 63042-301:2026, which is a technical specification, applies to on-site acceptance tests of electrical equipment with the highest voltages of AC transmission system exceeding 800 kV and its protection and control system.The electrical equipment exceeding 800 kV includes the following items:- power transformers;- circuit-breakers;- gas insulated switchgear (GIS);- gas insulated transmission line (GIL);- surge arresters;- voltage and current transformers;- shunt reactors;- series compensators;- insulators;- disconnectors and earthing switches;- high-speed earthing switches (HSES).This second edition cancels and replaces the first edition published in 2018. This edition constitutes a technical revision.This edition includes the following significant technical changes with respect to the previous edition:a) new subclause with measurement of short-circuit impedance and load loss for on-site assembly transformer has been added;b) new subclause with measurement of no-load loss and current for on-site assembly transformer has been added;c) on-site acceptance test requirement for GIL has been added;d) new clause with protection and control system on-site acceptance tests has been added.
