Applications
Main Function
Indicate the fault line and fault point quickly, lessen the blackout area;
Shorten troubleshooting time,improving electricity and power supply reliability;
Accurately indicate the instant fault, which is conducive to rule out the power supply problems;
Providing technical means for find the hidden permanent fault point;
Shorten the search time to find the fault point, reduce the labor intensity of line patrol person;
Defining the responsibility of the fault area and responsible people;
Avoiding traditional multiple switch out,switch on,line patrol to the effects of power equipment.
Features
The shell using high strength and high transparency aeronautical material Fully Fashioned, and treated with nanotechnology, better perspectivity. resist filth, anti-aging, without maintenance, long service life.
Built-in high performance lithium battery, Service life can reach more than eight years.
The circuit board using special chip and MCU etc imported Components.
The shell made from aeronautical material and nano materials.
The clamp with nickel plating process, best magnetic conductivity, Install and Remove with Electricity.
Fault indication turn card with strong visual,it can clear instructions with light in the night, and the color not fade under sun ultraviolet light for a long time.
Working Principle
When the power supply circuit has a short circuit or earth fault occurs, the short circuit current or earth fault current make electromagnetic field changes, fixed in cable sensors on the measuring coil produce pulse signal, when the value of the pulse signal reach or more than the set of fault current value, fault indicator automatically memory fault state, fault indicator will show the red flags and the LED lights flashing issued instructions, the staff through fault indicator signal can promptly and accurately to line fault location, timely troubleshooting, restore power supply.Product Drawing
Used to judge the short circuit fault indicator diagram
As line 2# B phase 2,5,8 indicator and line 2# C phase 3,6,9 indicator turn red, but the 11,12 indicator still show white, that judged the point D happen short circuit.
Used to judge the earth fault indicator diagram
As line 2# C phase 3,6,9 indicator turn red,but the 12 indicator still show white, that judged the point D happen earth fault.
