Short Circuit & Earth Fault Indicator DJ-3100
We Xiamen Leelen High Voltage Electric Co.,Ltd,is a professional OEM/ODM manufacturer about switchgear conponents,such as voltage indicator,heater,short circuit and earth fault indicator,blocking magnet,Led light,voltage sensor,temperature and humidity controller,etc
Short Circuit & Earth Fault Indicator DJ-3100
General Information
The short circuit & earth fault indicator DJ-3100 is used for detecting the short circuit and earth fault of the electrical equipment.
In order to avoid serious accident in distribution power networks,especially those in which a large number of ring main units are used, the upper level system must trip off within the setting time when a short circuit or earth fault occurs in the lower level.
This indicator is used to locate and indicate the fault section so that maintenance staff can locate and then cut off the fault section circuit quickly based on its signaling information.
And then resume no fault section timely. It will reduce the working time and minimize the region of power cut.
