What is the main function of the fault indicator?
The fault indicator is mainly used in the ring network distribution system, especially in the system that uses a large number of ring network load switches. If a short-circuit fault or ground fault occurs in the next-level distribution network system, the upper-level power supply system must be Disconnect within the specified time to prevent major accidents. By using this product, you can mark out the part where the fault occurs. Maintenance personnel can quickly find the faulty section according to the alarm signal of this indicator, and disconnect the faulty section, so as to restore the power supply of the fault-free section in time, which can save a lot of working time and reduce the time and scope of power outage. Now the northern power grid fault indicator is used in a large area, power supply companies and enterprises have been widely accepted, and the southern region is in the initial stage of use. At this stage, most of the methods for line fault location still use the installation of fault indicators. The disadvantage is that the number of poles required is large and each pole must be installed and used. If you want to save costs and reduce the risk of fault indicators and online location, you can use a new generation of offline overhead line fault location devices. The advantage of this fault location method is that no fault indicator is required, the investment cost is low, the fault location is accurate, and it is safe and reliable.
