Overrunning relay protection

This scheme is based on the intuition that, faults typically short circuits, lead to currents much above the load current. We can call them as overcurrents. Over current relaying and fuse protection uses the principle that when the current exceeds a predetermined value, it indicates presence of a fault (short circuit). This protection scheme finds. In contrast, there can be situations where for the purpose of selectivity, phase angle information (always relative to a reference phasor) may be required. Figure 2 shows such a case for a radial system with source at both ends. Consequently, fault is fed from both the ends of the feeder. To interrupt the fault current, relays at both ends of the f. Consider a simple radial system, which is fed from a single source. Let us measure the apparent impedance (V/I)at the sending end. For the unloaded system, I = 0, and the apparent impedance seen by the relay is infinite. As the system is loaded, the apparent impedance reduces to some finite value (ZL+Zline) where ZL is the load impedance and Zline. Differential protection is based on the fact that any fault within an electrical equipment would cause the current entering it, to be different, from the current leaving it. Thus by comparing the two currents either in magnitude or in phase or both we can determine a fault and issue a trip decision if the difference exceeds a predetermined set valu. -

What does ks represent in relay protection
The KS relay is a polyphase compensator distance type relay used with the type KD distance relay to prevent tripping while out-of-step or out-of-synchronism conditions exist on the system. It does not prevent or delay the type KD relay from tripping on phase-to-phase faults within its protective. Accurately detecting and protecting against single-phase-to-ground faults is one of the most challenging tasks in distance relay protection. At the heart of this challenge lies the K factor, a parameter integral to ensuring accurate relay operation and fault identification. A sensitive relay improves the reliability of the system. The norms of protection of generators, transformers, lines and capacitor banks are also given. These numbers are based on a system that is adopted by a standard for automatic switchgear by Institute of Electrical. -
