PD IEC/TS 62332-3 discusses electrical insulation systems (EIS).
PD IEC/TS 62332-3 is a Technical Specification, is applicable to EIM and EIS containing solid and liquid components where the refrigerant, oil, and thermal stresses are the dominant ageing factor, without restriction to voltage class.
PD IEC/TS 62332-3 on electrical insulation systems is relevant to:
PD IEC/TS 62332-3 covers the evaluation and qualification of EIM and EIS which are applied to motor-compressors for the refrigerator or air conditioner. PD IEC/TS 62332-3 contains the evaluation items which are important to maintain the equipment performances in the refrigerator oil and refrigerant at high temperature and high pressure.
The main procedures consist in the evaluation of EIM and EIS endurance for refrigerator and oil at high temperature and high pressure. It describes how to evaluate the mechanical, thermal and chemical degradation of the performances of EIM which have deep relation to keep the sound condition of the equipment.
This simplified Technical Specification provides a test method for sealed tube testing. The sealed tube should contain all the primary EIM elements in relative component ratios which compare with the actual electrotechnical device.
Overall PD IEC/TS 62332-3 helps demonstrate the performance and capabilities of hermetic motor-compressors, ensuring that they play a positive role in the operational efficiency of overall EIS.
