If a client desires abbreviated documentation, we are prepared to provide such. New directional elements and distance polarization methods make ground fault detection more sensitive, secure, and precise than ever. The equation now reads :T = + K3 EI sin (150” - 0) for a relay where y = 60°.This is recognizable as a direc- tional element, wherein positive, contact-closing, torque is realized for values of 0 between 330° and 150°, with maximum positive torque at 0 = 60°. As the impedance of a transmission line is directly proportional to its length, it can easily be concluded that a distance relay can only operate if fault is occurred within a predetermined distance or length of line. 1.04 Model No. Percentage restrained differential relays measure the individual branch currents and quantify the through current in the zone of protection. Clipping is a handy way to collect important slides you want to go back to later.

As the time setting multiplier is 0.1 here, actually the moving parts of the relay have to travel only 0.1 × 100% or 10% of the total travel distance, to close the relay contacts. Accordingly, relay settings = current plug tap 5 A (100%) and time multiplier 0.8. Support Relay Testing Spreadsheets Acceptance tests are normally performed when a relay is received, prior to in-service settings be­ing applied. The number of relay elements required for complete schemes is usually quite large. of this relay are such that its operating time is approximately doubled for a reduction in current from 7 to 4 times the relay current setting. 9o�#.��}� �*&� n�: REF relay setting calculation REF RELAY SETTING CALCULATION.
