Abstract

In the distribution network, the single phase grounding fault of potential transformer (PT) caused by burning phenomena occur. PT transient characteristics of the primary side current, On the basis of single-phase grounding fault and the equivalent model simulate PT transient characteristics of the primary side current. The main causes of PT failure are deduced for distribution network single-phase ground capacitor current value caused by a larger. The simulation of a group of 6kV PT by using power system simulation software PSCAD/EMTDC, and the comparison of the three solutions: the PT of one side through the non-linear resistor (harmonic elimination device), Open triangle parallel resistance and the system neutral grounding via arc suppression coil. Finally obtains that the neutral point through the arc suppression coil grounding is the most the right way to solve this problem in the distribution network.
