PD IEC/TR 61857-2:2015

This standard PD IEC/TR 61857-2:2015 Electrical insulation systems. Procedures for thermal evaluation is classified in these ICS categories:

• 29.080.30 Insulation systems

This part of IEC 61857 gives guidelines to identify the appropriate test method to be used for the evaluation of a proposed Electrical Insulation System (EIS). Some of the standards are for evaluation and classification of the EIS, while other standards identify the appropriate method to evaluate single or multi-factor stresses of a proposed or of an established EIS.

This Technical Report is applicable to existing or proposed EIS used in electrotechnical products across a wide range of operating voltages of IEC Standards. The report takes care to select the appropriate standard based on construction and intended operating conditions.
