Coincidence Type Phase Comparator: The basic concept of phase comparison is simpler in that it is possible to deal with signals of equal strength whose coincidence (or noncoinecidence) is readily…
Phase Comparator Circuit: Phase Comparator Circuit technique is the most widely used for all practical directional, distance, differential and carrier relays. If the two input signals are S1 and S2…
What is Comparator in Electronics? - Classification and Applications A circuit used to mark the instant when an arbitrary waveform attains some particular reference level is called a comparator. The…
Comparators in Power System Articles: Static Amplitude Comparator: If the two input signals are S1 and S2 the amplitude comparator gives positive (yes) output only if S2/S1 ≤ K (Fig.…
Static Amplitude Comparator: If the two input signals are S1 and S2 the amplitude comparator gives positive (yes) output only if S2/S1 ≤ K (Fig. (11.1)), S1 is the operating quantity…
Phase Comparison Carrier Protection: The phase comparison pilot-relaying operates on the principle of comparing the phase position of the currents at the two ends of the protected section. The Phase…
Comparator Equation in Power System Protection: Comparator Equation in Power System Protection - Taking a very general case to cover the complete range of conventional relay characteristics, let S1Â and S2…
Microprocessor Based Digital Relay: With the fast development in large scale integrated (LSI) technology, sophisticated and fast microprocessors are now available. With the rapid growth of modern complex large power…
