Research on Interference Mechanism of 25 Hz Phase Sensitive Track Equipment from Unbalanced Current
In a 25-Hz phase-sensitive track circuit, traction backflow is unevenly distributed in the two rails, resulting in interference caused by the 50 Hz unbalanced current, which leads to misoperation of relays and other equipment in the circuit.
