A New Method to Measure Capacitance Current of Power Grid that Grounded Via Arc-Suppression Coil with Magnetic Bias
It is difficult to measure system capacitance current to earth in resonance grounding technology. To this common problem a method of injection signal is taken to measure capacitance current to earth accurately. The neutral point PT of arc-suppression coil is as signal injection TV, injecting a 10 Hz current signal from the secondary and measuring the10 Hz voltage at the PT installed on the generatrix. Arc-suppression coil with magnetic bias is used, and the control system of two CPU mode is designed based on microprocessor 80C196KC. The resonance compensation device has many advantages such as reasonable structure; quick response; high compensation precision, and it is reliable without any mechanical actions.
