Abstract
Property and arrangement of Ultra-High- Frequency (UHF) sensors installed on GIS cannot be evaluated quantitatively with existing sensitivity verification method based on equivalent pulse. It is difficult to obtain standard pulse equivalent to some partial-discharges; therefore, no uniform pulse injection method can be used. To solve this problem, a property comparison and evaluation method for UHF sensors installed on GIS based on transfer function is suggested.Performance and arrangement of UHF sensors are evaluated by measuring and comparing transfer functions of every two adjacent UHF sensors installed on GIS. By using this method, some sensors installed on 550kV GISs are evaluated in two substations.A damaged sensor is detected and some poor arrangement is found out.This evaluation method is effective to find out disabled sensors and poor arrangement.This work is of great importance to verify effectiveness of GIS partial discharge detection.关键词
