Analysis for Electric Coupling Coefficient Functions in Three Phase VFT Voltage Measurement of GIS
In order to measure the VFT phase voltage on three-phase enclosed GIS
3 capacitance sensors are needed. Each capacitance sensor is coupled with the electric field of three phases voltage. This paper describes the basic properties of the electric coupling coefficient functions
the maximum value of which is determined by an approximate analytic expression.
