Webb– Explore testing of basic Ground-Mho and Ground-Quad characteristics. Note that we will use a ‘representative’ relay in our presentation / discussion: the SEL-321 relay.\爀屲This presentation is int\൥nded to be vendor neutral, and the concepts discussed should apply to ground-distance relays from any vendor. WebbDistance relay with Mho characteristics is simulated to mitigate the charging current effect of combined system with significant part of underground cable. Th e combined system …

Comparison between Mho and quadrilateral settings for

WebbEquation (2) can be expressed in per-unit (pu) values as: Ipu I puSP( )()= (3) 2) Real CT Behavior Real CTs have copper losses, core losses, and leakage flux and require a certain current to magnetize the core. As a result, the secondary current of a CT is not perfectly proportional to the primary current. For most operating conditions, CTs WebbOperating Characteristic of Mho Relay In this type of Relay, the working torque can be obtained through the V-I characteristic & limiting torque through the characteristic of … WebbThe dip angles of the reactance relay, the quadrilateral relay's base, the load blinder, and the relay's hypotenuse are 7°, 7°, 80° and 105°, respectively.
