IEC 62271-111:2012

IEC 62271-111:2012(E) applies to all overhead, pad mounted, dry vault and submersible single or multi-pole alternating current automatic circuit reclosers and fault interrupters for rated maximum voltages above 1 000 V and up to 38 kV. This second edition cancels and replaces the first edition, published in 2005, and constitutes a technical revision. The main changes with respect to the previous edition are as follows:<br /> a) addition of exclusion of devices with dependent manual operation to 1.1;<br /> b) harmonization of the amplitude factor kaf used for calculating the TRV for cable connected systems consistent with recent harmonization of the circuit-breaker standards between IEEE and IEC;<br /> c) deletion of requirements for radio influence voltage (RIV) tests;<br /> d) addition of specifications and ratings to cover the cutout recloser and its special requirements.<br /> This standard has been jointly revised by Switchgear Committee of the IEEE Power and Energy Society, in cooperation with subcommittee 17A: High-voltage switchgear and controlgear with reference to IEEE Std C37.60-2012(E).<br /> <br /> This publication is to be read in conjunction with <a href="http://webstore.iec.ch/webstore/webstore.nsf/ArtNum_PK/38507">IEC 62271-1:2007</a>.
