DS-1DX Overhead intelligent short circuit fault indicatorDetailed product description：

DS-1DX overhead intelligent short circuit fault indicator is made of aviation materials with high strength and perspective in one step, and processed by nanotechnology. It has better perspective, anti pollution, anti-aging and maintenance free
Protect and have a long service life.
High performance lithium batteries have a lifespan of over 8 years.
A circuit board composed of imported components such as dedicated chips and microcontrollers.
Shell made of aviation and nanomaterials
Nickel plated and highly magnetic. A card wire structure that can be installed with electricity
Using red fluorescent paint, it has strong visual appeal and can clearly indicate under nighttime light. It also has a display rotation that does not fade under long-term outdoor ultraviolet irradiation

Function and benefits
Quickly identify the faulty line and point, and reduce the area of power outage;
Shorten troubleshooting time, improve electricity sales and power supply reliability;
Accurately indicating instantaneous faults is beneficial for eliminating power supply hazards;
Provided technical means for locating hidden permanent fault points;
Shortening the search time for fault points and reducing the labor intensity of line patrol personnel;
Define the fault responsibility area and clarify the responsible person;
To avoid the impact of traditional multiple line pulling and closing patrols on power equipment;

Principle of operation
Principle of short circuit detection: Based on the phenomenon of short circuit, the current undergoes a sudden positive change at the moment of short circuit, and the protection action is based on power outage.

Schematic diagram of fault indication used to determine short circuit:



If the indicators 2, 5, and 8 of phase B on line 2 and the indicators 3, 6, and 9 of phase C on line 2 turn red while the indicators 11 and 12 remain white, it can be determined that a short circuit fault has occurred at point D
