Relay protection quadrilateral protection characteristics

Quadrilateral characteristics is one of the most sophisticated and widely-used impedance-based relay protection schemes in modern electrical power systems. In this. Abstract—This paper analyzes factors affecting the performance of current polarized reactance elements and provides guidelines to ensure the security of Zone 1 quadrilateral distance elements. These relays may sometimes be set based in percentages of the line impedances, for example a typical setting for zone 1 is 80% of the impedance of the line in order to not reach the remote end, the zone 2 can. Other types of impedance relays are e. loss of synchronism protection, loss of excitation protection, or impedance automatics like fault locator. Also. Abstract—Quadrilateral distance elements can provide significantly more fault resistance coverage than mho distance elements for short line applications.

Relay Protection Microcomputer Distance

Such protection relays are known as “distance protection relays” and only function in case of faults that occur between the location of the protection relay and the chosen reach point. A form of protection against faults on long-distance power lines is called distance. By varying commands to the analogue multiplexer the required input signals for different relaying characteristics such as impedance, reactance, MHO and directional relays are obtained. A Fourier block estimates the fundamental voltage and current signals. The relay operation is purely depending upon the magnitude of the circuit current and voltage, typically the ratio of the circuit to be protected is calculated. Here the prefix word distance.
