IEEE P117/D12, May 2015 IEEE Approved Draft Standard Test Procedure for Thermal Evaluation of Systems of Insulating Materials for Random-Wound AC Electric Machinery
Institute of Electrical and Electronics Engineers (IEEE)
Scope
This is a standard test procedure for the thermal evaluation and qualification of electrical insulation systems for Random-Wound AC Electric Machinery, where thermal degradation is the dominating aging factor. This procedure compares the relative thermal performance of a candidate Electrical Insulation System (EIS) to that of a reference Electrical Insulation System. This standard covers insulatio...
