Time Delay Circuit: Several choices are available in the selection of suitable circuits for obtaining Time Delay Circuit depending on the magnitude of the time delay required. Delays of the…

Level Detector: Schmitt trigger or level detector circuits are very often employed in static relay circuits as a final stage before the trip coil circuit of the circuit breaker. The…

Switching Transistor: The characteristics of modern Switching Transistor are specially suited to the functional requirements mentioned already. These along with the other Semiconductor production of static relays. The properties particularly…

Generator Transformer Protection: Generator Transformer Protection - Protective relays, being component parts of electrical switchgear, should be closely associated with the control section of such systems, e.g. indicating and signalling systems. Thus the signalling and indicating systems…
