The quick and precise locating of partial discharge(PD) inside switchgear is important in eliminating the hidden faults promptly and ensuring the safety and stability of the power system. PD source will be located at a certain compartment of switchgear by setting up multiple sensors with different arrangement. Then, using the hyperbolic method and spatial grid search method can finally determine an accurate position of PD source in a compartment based on the simulation results of a simplified compartment XFDTD model. A switchgear PD location experimental platform is established in laboratory which verify the validity of the positioning method.
