40 5kv current transformer detection systems

40 5kv current transformer detection systems

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.
