Live working - Insulating aerial devices for mounting on a chassis

Scope

IEC 61057:2017 is applicable to <i>insulating aerial devices</i> for mounting on a <i>chassis</i>, to be used for live working on electrical installations at nominal voltages above 1&nbsp;000V&nbsp;r.m.s. AC in the range 45&nbsp;Hz to 65&nbsp;Hz and 1&nbsp;500V DC. This second edition cancels and replaces the first edition published in 1991 and IEC&nbsp;TS&nbsp;61813:2000. This edition constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous edition:

a)&nbsp;&nbsp; general review of the requirements and test provisions;

b)&nbsp;&nbsp; preparation of the elements of evaluation of defects, and general application of IEC&nbsp;61318:2007;

c)&nbsp;&nbsp; distinguishes between tests for hollow booms and those for foam filled booms;

d)&nbsp;&nbsp; references ISO&nbsp;16368 for particular mechanical tests;

e)&nbsp;&nbsp; further information on vacuum protection and leakage current monitoring and a mandatory requirement that aerial devices for bare hand work be fitted with a permanently installed lower test electrode system;

f)&nbsp;&nbsp;&nbsp; <em>controls</em> of high electrical resistance;

g)&nbsp;&nbsp; reference to SAE for insulating hydraulic hoses;

h)&nbsp;&nbsp; inclusion of IEC&nbsp;TS&nbsp;61813 for care, maintenance and in-service testing of aerial devices with insulating booms.
