Abstract

The paper contains the results of research regarding the influence of asymmetry of isolation parameters of 6—10 kV overhead transmission lines relatively the ground to meet the requirements of isolation serviceability. It has been shown that besides serviceability conditions, based on electric safety reqiurements for determination of isolation state we can apply serviceability, based on determination of power losses in isolation due to leakage currents. The results of investigation are given for two cases of environment condition — wet weather and dry weather. It was also shown, that for dry weather conditions both requirements of serviceability are equivalent, and can be applied simultaneausly for definition of technical state of network insulation. Nonexpediency of application of serviceability conditions, based on determination of power losses in insulation due to leakage current in case of wet weather is proved, as these conditions meet considerably lower requirements regarding technical state of insulation and are not viable to meet electric safety requirements.
