Fault Indicator Monitoring System Improve Power Supply Reliability And Economic Benefits

A Fault Indicator Monitoring System is an intelligent device mounted on a power line for on-line detection, indicating short circuit and single phase ground fault. Can be applied to overhead lines and cable lines of the ring network counters, opening and closing, power distribution room switchgear and other electrical equipment. After the line failure, patrol line staff can use the indicator alarm display, quickly determine the fault section, and find the point of failure. With the Fault Indicator Monitoring System of communication, it can realize the remote transmission of the fault signal, combine the communication terminal equipment and monitor the background, constitute the fault automatic positioning system, realize the quick positioning of the fault point, shorten the power failure time, restore the power supply quickly, improve the power supply reliability and the economy benefit.

Display: flop display, flash alarm, 360 ° range can be observed;

Communication: with a wireless communication function can be far fault signal, and communication terminals to achieve two-way communication;

Short-circuit fault detection: the use of short-circuit current increment and relay protection features to determine the characteristics of the current fault, with the switch to maximize the anti-time trip time;

Ground fault detection: the use of signal injection method to detect single-phase ground, to determine the ground line;

Load monitoring: real-time monitoring of line load;

Live state detection: to determine the line power failure, power supply status;

Reset: support automatic reset, remote remote control reset;

Anti - maloperation: put an end to the phenomenon of mismatch caused by inrush current;

Charged handling: can be charged with installation and removal;

Anti-corrosion: structural parts using anti-corrosion materials.

The Fault Indicator Monitoring System originated in Germany in the 1980s and was designed to indicate the way in which the short-circuit current flows through the distribution line to help people find the point of failure. China from the nineties began to introduce and learn foreign Fault Indicator Monitoring System development technology, and gradually evolved into a remote monitoring with the communication function of the distribution line fault location system. The system to Fault Indicator Monitoring System probe, terminal and background master station, as shown below. Overhead Fault Indicator Monitoring System and the terminal generally in a small wireless ad hoc network communication to achieve data communication, and cable Fault Indicator Monitoring System and the terminal may be a small wireless ad hoc network or optical fiber communication to achieve data delivery, due to the probe And the communication distance between the terminals is short, the data transmission rate is low, the logic level is simple, there is generally no communication reliability problem.
