What is PD IEC/TS 60216-7-1-Thermal endurance properties of electrical insulation materials about?
PD IEC/TS 60216-7-1 discusses the thermal endurance properties of electrical insulation materials. PD IEC/TS 60216-7-1 describes the procedure for the evaluation of the thermal endurance of electrical insulating materials, based on thermal analysis methods for the evaluation of the activation energy of the thermal degradation reaction and a conventional life test providing a life point in the thermal endurance graph.
The purpose of the test procedure is to estimate the relative temperature index (RTE). Predictions of thermal endurance based on this procedure are limited to ageing reactions where one single reaction is predominant and directly correlated to the end-point criteria for a specific application.
Who is PD IEC/TS 60216-7-1-Thermal endurance properties of electrical insulation materials for?
PD IEC/TS 60216-7-1 on thermal endurance properties of electrical insulation materials is useful for:
- Electrical engineers
- Thermal endurance researchers
- Electrical insulator manufacturers
Why should you use PD IEC/TS 60216-7-1- Thermal endurance properties of electrical insulation materials?
The existing procedures of the IEC 60216 series for the evaluation of the thermal endurance of electrical insulation material can be time-consuming. These methods are therefore of limited use during the development of new materials or screening of existing products for use as to material in electrical insulation. Non-conventional methodology for thermal endurance characterization which can reduce further test times is considered in PD IEC/TS 60216-7-1.
The analytical test methods described in PD IEC/TS 60216-7-1 may satisfy the demand of shortening the insulating material characterization procedure, if used with care and considering the restrictions these methods imply. At present, the universal applicability and the accuracy of these methods are not validated, thus a round-robin test is required to provide an IEC standard based on these procedures. PD IEC/TS 60216-7-1 is therefore published as a technical specification.
