IEEE 1783 Defines Test Methods for Insulators in Sub-Freezing Conditions
September 10, 2009 // Published as a news service by IHS
The Institute of Electrical and Electronics Engineers Standards Association (IEEE-SA) approved IEEE 1783 - Guide for Test Methods and Procedures to Evaluate the Electrical Performance of Insulators in Freezing Conditions.
This standard defines test methods for insulators during sub-zero weather conditions. It includes test methods for substation and line insulators at distribution and transmission voltage levels.
The test methods detail measures to reproduce the environmental and insulator parameters that influence the risk of flashover in freezing conditions. Statistical methods are also recommended to assist in the insulator selection process.
The standard was sponsored by the IEEE Dielectrics and Electrical Insulation Society.
According to IEEE-SA, the guide consolidates the information learned in the past decade and recommends reproducible test methods for selecting adequate insulators.
