Timer: Timer is an instruction that waits a set amount of time before doing something. The different kinds of timers are available with different manufacturers. Most of the timers are: ON-delay Timer: This type of…
Pilot Wire Protection Relay: In this case the auxiliary Pilot Wire Protection Relay are provided to carry the information signals from one end to the other. Protective systems requiring the use of pilot wires on…
Current Source Inverter Fed Induction Motor Drive: Current Source Inverter Fed Induction Motor Drive - In a voltage source inverter fed induction motor the applied voltage to the stator is proportional to the frequency, with…
SI Unit of Electrical Resistance: SI Unit of Electrical Resistance - When a current flows in a material, the free electrons move through the material and collide with other atoms. These collisions cause the electrons…
Amplitude Detection Process: Amplitude Detection - The process of demodulation demands that the modulated wave has some definite average value and the carrier wave is separated out. Hence in demodulation of an AM wave two…
Measurement of Information in Communication System: Having said what information is not (it is not meaning), we now state specifically what information is. Accordingly, information is defined as the choice of one message out of…
What is Active Filters and types of active filters: Active Filters is a circuit that is designed to pass a specified band frequencies while attenuating all the signals outside that band. It is a frequency selective circuit. The…
Breakdown in Composite Dielectrics: It is difficult to imagine a complete insulation system in an electrical equipment which does not consist of more than one type of insulation. If an insulation system as a whole…
Starting Methods of Synchronous Motor for LCI: It has been pointed out that a Starting Methods of Synchronous Motor for LCI, even though complicated in its construction, has an advantage that it can provide the…
Distance Protection: Both time-graded and pilot-wire system are not suitable for the protection of very long high voltage transmission lines. The former gives an unduly long time delay in fault clearance at the generating station…
