Based on the author s experience in adjustment test and the study on the diagram of diagnosis and detection of shortcircuit,the principles of coordination between diagnosing and detecting shortcircuit and automatic reclosing in D.

The system can inspect the change of current in real time and perform such functions as alarming, opening, automatic reclosing, recording and faults displaying.

This paper introduces the coordination of automatic reclosing of circuit breaker in line-transformer strings with 3/2 connection and the relay protection.

Study of auto-reclosure strategy for high temperature superconducting cable;

Aiming at the unreliable factors that the traditional electromagnetic ARD device has more action grades and adhering of contact, using PLC to realize the auto-reclosure and making the design for hardware and software, the used components is fewer, accident chance is much lower.

On the basis of analyzing the factors influencing the measurement accuracy of traveling wave velocity,the influence of traveling wave velocity on fault location accuracy and existing measuring methods of traveling wave velocity, using the wave of single-phase auto-reclosure to measure the traveling wave velocity is proposed for single-phase gr.

Implementation of intelligent auto-reclosing with DSP;

Case study of power system auto-reclosing logic;

A new technique of employing auto-reclosing technology for single-phase-to-ground fault clearing in non-valid grounded power systems is also presented.

An automatic reclosure setting software package based on object_oriented method is introduced.
