A Method for the Resistive Current Calculation of MOA Based on Phase Analysis
It is crucial to keep track of the Metal Oxide Arrester (MOA) working condition as it is a commonly utilized overvoltage protection device in power system. Monitoring the resistive current of MOA is the most efficient way to ascertain its operational state since the resistive current is the most observable characteristic when MOA is faulty. Based on phase analysis, this paper proposed a new method for obtaining the resistive current of MOA. By taking into account the effect of inter-phase coupling capacitance and the third harmonic in power system, a model of three-phase MOAs operated at the 10kV was created in MATLAB for the resistive current calculation under different conditions. The simulation result shows that the resistive current of MOA can be precisely calculated, which can be served as an effective way for the accurately monitoring of each MOA’s condition.
