A novel GIS breakdown location method based on natural frequency of transient voltage
High Voltage, Volume 10, Issue 4, Page 856-875, August 2025.Abstract During on‐site withstand voltage tests of gas‐insulated switchgears (GIS), once a breakdown occurs, it is hard to locate the breakdown position due to the intricate branch structures and minimal breakdown energy. The existing methods may require the placement of a large number of sensors with unsatisfactory accuracy, which adversely affects ...
