Grounded Fault Indicator Species Are There?

With the development of the electric power industry, increasing demand for the quality of power supply, hence a variety of fault indicators are used in the power line road, Teli grounded fault indicator technology is broadly divided into two types:

The first grounded fault indicator for overhead, mainly used in the overhead power lines for earthing and short circuit fault detection circuit for monitoring temperature and operation condition;

Second ring main unit cable fault indicator, also often called a temperature fault indicator, mainly used in ring-network Cabinet, branch boxes, cable system, used for detection of grounding fault line, load and temperature conditions.
