Therefore PSM of the relay is, 5 / 1.5 =3.33. The urgent one is the overlap, which may occur for the same protection zone. Time Setting Multiplier of Relay. setting is 100/5 A ⦠It is common for relay engineers to focus on dependabilityâalways clearing the fault. Scope This document introduces the application of the distance protection function in the REF 542plus feeder terminal. _____ 1. Consider a simple radial system, which is fed from a single source. Distance Relay Setting Calculation [ylyxwxq8pqnm]. Distance Relay Setting calculation - Free download as Excel Spreadsheet (.xls / .xlsx), PDF File (.pdf), Text File (.txt) or read online for free. Time Multiplier Setting used to change the value of operation of the relay. ETAP StarZ Transmission Line Protection software provides tools to examine and check the performance of distance relay settings, user logic, and communication interfaces. This technical article will cover the gathering of information needed to calculate protective relay settings, the setting calculations for the various protective functions, typical generator/turbine withstand times for abnormal operating conditions, and the math associated with various types of impedance elements. There are two basic types of distance relaying - phase and ground. Distance relaying is a method of using the calculated impedance to locate the fault. PROTECTIVE RELAY CALCULATIONS AND SETTINGS PCSBR COM. During the calculation of operation setting for different protection zones of the distance relays, some problems have been raised.

The relay is designed to provide fast and selective fault clearance on transmission and subtransmission cables and overhead lines with or without series capacitor compensation. Resistive Reach of Distance Relay Characteristics is defined by the fault resistance for which the distance relay characteristics is defined. Time Multiplier Setting (TMS) Time Dial Setting (TDS) Example: Calculate the plug setting and time multiplier setting for an IDMTL relay on the following network so that it will trip in 2.4 s (see Figure 1).The relay characteristic is shown in Figure2.The C.T. setting ... 7968 distance relay setting and apparent. Understanding Distance Protection & distance protection relay Why Distance Protection > Since the impedance of a transmission line is proportional to its length, for distance measurement it is appropriate to use a relay capable of measuring the impedance of a ⦠In MHO type distance relay the major drawback is that resistive reach is defined by the impedance reach and line angle and hence it is not independently settable in the relay. relay j. TDS for relay j is selected within a range as follows: TDS min â¤TDS j â¤TDS max âj (13) where TDS max and TDS min are the maximum and min-imum values of time dial setting respectively, for relay j. TDS max and TDS min are set to 0.05 and 1 respectively [21] with a CTI of 0.3s [22]. relay setting calculation setting the generator protective relay functions eep. The operating time of an electrical relay mainly depends upon two factors : How long distance to be traveled by the moving parts of the relay for closing relay contacts and; How fast the moving parts of the relay cover this distance. Often, distance relaying is used in a communication assisted scheme to provide high speed tripping. 3.
