MASKED OUTPUT DIRECTIONAL OF THE ELEMENT ELEMENT Vpol OUTPUT PICKUP Figure 6 9 Block Diagram of a Directional Overcurrent Element The purpose of the directional element is to monitor the overcurrent element whenever the torque control setting is YES and impede its pickup if the current flows in the opposite direction from the chosen one That is it must first see the direction start the directional element and then detect a sufficient level to generate the trip If the directional element inhibits the operation of the overcurrent element the timing function will not start If the inhibition occurs once the timing has started it will reset so that the timing will start again from zero if the inhibition disappears In any case a trip requires the timing function to be uninterrupted The directional element requires voltage and current thresholds to be able to see the trip direction These values are 1 V and 0 02 In where In is the IED s nominal current Once these thresholds have been reached the directional element can start if the conditions exist in the direction of the current flow If the current has not reached either of the two thresholds once the element has picked up the directional element will reset 6 12 PNY B71V1206J ath 7IVD Distribution Protection and Control grid automation ZIV GRID AUTOMATION S L Zamudio 2012 Chapter 6 Description of the Operation of the Protection Subsy
