摘 要: | 为了测量GIS中三相快速瞬态电压,需要三个电容传感器,而每个传感器同时受三相电压的电场耦合。文中讨论了三相共壳式GIS在完全对称布置和不完全对称布置情况下,电场耦合系数函数的基本特性。并且给出了电场耦合系数函数最大值的一种简便确定方法。

Analysis for Electric Coupling Coefficient Functions in Three Phase VFT Voltage Measurement of GIS |
| |
Abstract: | 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. |
