Comparison of Power Loss Due to Corona Phenomena Model with Peek's Formula in High Voltage 115 kV and 230 kV System

This paper studied the power loss due to corona phenomenon with Gary's model and Peek's formula using Matlab program for the power loss simulation in 115 kV and 230 kV system that the corona loss varies with transmission conductor radius and spacing. The corona phenomenon effects on leakage capacitance and inductance of transmission line. The leakage current would increase in the condition of the corona incepted. The power loss due to corona has an inverse variation with radius and spacing of conductor. The Gary‘s model is not suitable for 115 kV. Due to the operating point of power system, the model losses had the value 7.5% with difference from the formula for 115kV system and 14.5% for 230 kV system.
