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.
