DS-JDG Multi functional (four in one) intelligent line fault indicatorDetailed product description：

DS-JDG has the same appearance, features, functions, applications, and technical specifications as DS-JDX. They have the same internal structure, but DS-JDG is equipped with a night time luminous device.

Overview

DS-JDG multifunctional (four in one) intelligent line fault indicator: In response to feedback from a large number of domestic customers, it is necessary to wear a power strip to see the fault flipping effect at night, and to find the fault point one by one, the light irradiation must be carried out. The visual distance is short, and the speed of fault searching at night is relatively slow. Therefore, our company has added a very fast and intuitive night searching light emitting device to the original two in one product to meet customer requirements, namely the DS-JDG series that lights up at night during the day flipping.

working principle
The principle of grounding short circuit fault is the same as that of the two in one, and three phototubes and high brightness light-emitting tubes have been added to the original two in one fault indicator. When a line fault occurs during the day, the indicator will flip over to display. When it gets dark at night, the resistance of the photoelectric tube increases, so the microcontroller is turned on, the flip card is reset, and at the same time, the light-emitting tube is turned on to work. When dawn broke, due to the indicator not having reached the scheduled reset time, the resistance of the photoelectric tube received light decreased, and the microcontroller reset, cutting off the operation of the light-emitting tube and turning on the flipping mechanism, thus restoring the flipping indicator.

Scope of application
At the middle section and branch entrance of the long line, the fault section and branch of the line can be indicated.
At the exit of the substation, it can be determined whether the fault is caused by the user.
At the user's transformer inlet, it can be determined whether the fault is caused by the user's fault.
At the connection between cables and overhead lines, it is possible to distinguish whether the fault is in the cable section
