DC Leakage Current Warning Equipment

 

 

This equipment is used to detect the leakage current and diagnose the insulation of DC power supplies at distribution panels installed in substations of railway companies or power plants and substations of power companies.
If current leaks in power supply circuits, this equipment outputs an alarm signal notifying CC (central control center) that the current has leaked, and also displays detailed information such as the leakage occurrence time, name of leaking circuit number and ground voltage on a TFT liquid crystal display. As a result, this equipment realizes an early recovery from the leakage fault. Moreover, its insulation diagnosing function helps preventive maintenances by specifying the circuits that may cause leakage faults.
YGF-M2 type can monitor up to 128 circuits when four Detecting Units are connected. YGF-M3T type has the same function as YGF-M2. Besides, this type is much compact comparing with YGF-M2 because the operating Unit and detecting Unit of YGF-M3T are integrated to correspond to the small-scale plants with small number of circuits. YGF-M3T can monitor up to 16 circuits.
