A proposal for intensified inspection and acceptance tests of composite insulators as an addition to the guidelines of IEC 61109 Ed. 2: 2008 and IEC 61952 Ed. 2: 2008

The paper provides an example of a test programme, which aims to add to the evaluation of composite insulators after they have being supplied. It is to be considered as a tool to prove the product quality versus the submitted reports from international standards. The proposed tests are not selected to discriminate against any particular material or manufacturer but rather to consider well accepted and recently developed test philosophies, in order to safeguard the quality of the supplied insulators, in particular for bulk volume contracts.
