GROUD-FAULT LOCATOR FOR MAGNETIC LEVITATION POWER FEEDING SYSTEM AND ITS METHOD

摘要

The present invention displays a fault position when a fault accident is generated for an early recovery when a ground fault accident of a ground coil for propulsion which is one of a ground facility of a magnetic levitation railway. The present invention includes an input unit which receives an output current signal of each system or each phase, a BPF which receives an output current signal from the input unit and removes an unnecessary signal, and a control unit which receives the output current signal passing through the BPF.
