    11 mins readAug 24, 2020The relay provides a high impedance to the current. The current will, for through loads and through faults, circulate in the current transformer circuits, not go through the relay. For a through fault one current transformer might saturate when the other still will feed current. For such a case a voltage can be achieved across the relay.

  • Current Sensing and Occupancy Detection for DCC – The N

    Commercial block occupancy detection systems for DCC typically use current transformers to sense current draw from locomotives or resistor wheelsets. The sensors are usually attached to stand-alone logic boards that turn outputs on or off to signal occupancy detection. Typically, these outputs are used to directly power signals.
