PPT-TRANSMISSION LINE FAULT MONITORING

BY VISHU KUMAR 1HK08EE055 Internal Guide WASEEM KHANUM INTRODUCTION Transmission line fault is monitored The steady state operating mode of a power system is balanced 3phase ac When the insulation of the system fails at one or more points or a conducting object comes in contact with a live point a short circuit or fault occurs. Balanced and unbalanced transmission line Transit time effect on a transmission line at high frequencies Dominance of the reactive component over resistive component Concept of distributed elements and conditions under which the lumped element circu Merrimac directional couplers are precision devices carefully designed for monitoring incident and reflected power Merrimac directional couplers are available in four different classes 1 Three port directional couplers 2 Four port bidirectional coup safety . in Photovoltaic Systems.
