Electrical properties of CFC and HCFC substitutes.

Author(s) : MEURER C., PIETSCH G., HAACKE M.

Type of article: Article, IJR article

Summary

Electrical properties of refrigerants are of importance as soon as bushings are surrounded by a refrigerant. This is the case e.g. for hermetic sealed motor compressors as well as for some control devices such as liquid level control units or capacity controls for compressors. This paper presents a survey of existing data for HFC refrigerants and presents new measurements for those HFC blends that have been identified as long term replacements for CFCs and HCFCs. The data collection includes permittivity, electrical conductivity and breakdown voltage. Values are given for the HFC blends R404A, R407C, R410A and R507 as well as for R134a.
