Overview
This part of IEC 63522 is used for testing along with the appropriate severities and conditions for measurements and tests designed to assess the ability of DUTs to perform under expected conditions of transportation, storage and all aspects of operational use. This document defines a test to check that a multipole relay is capable of transferring one source to another. The standard describes the test method and evaluation. Application of the document increases investment security for manufacturers and users and provides testing laboratories and manufacturers with defined specifications for testing.
