Testermeter- JDG-Z Overhead live line fault indicator, fault passage indicator(FPI),Permanent Fault,Transient Fault,Earth Fault
Characteristic:
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. Theshell made from aeronautical material and nano materials. Theclamp 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.

Function and Benefit
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. |
