how the apfc relay work
It work like a master slave flip flop if its not a logic 1 then its a 0.
cdg is circular disk gear relay which is electromagnetic relay
current relay are using for over current low state & high state.but potential relay are related to voltage.
The distance relay trips when a fault occurs at a distant or a remote place in the electric transmission line. There is a mechanism based on the impedance calculation of the distance of the transmission line after which it is accurately known where the fault has taken place. Thus the distance protective relay can trip the circuit & prevent the fault to be carried further and also can indicate the location of the fault.
Quenching diodes are used to protect the control circuit of a relay. Power is applied to a relay's coil to close it. When this power is released there is a backwards flowing pulse that can wipe out solid state devices like transistors, LEDs, chips, etc... The quenching diode is applied in parallel with the relay coil so that the cathode is on the positive side. During normal operation, the diode doesn't conduct and the relay operates normally. When the relay is switched off, the "reversed" back pulse is absorbed due to the low voltage drop of the diode which limits the spike.
APFC Exam date are 23rd sept so e-admit card will available before 15 days of the examination.
IT would be available around 5th September
How Negative phase sequence relay work
APFC stands for Automatic Power Factor Controller. It is a device used in electrical systems to optimize power factor by automatically adjusting the amount of reactive power supplied to the system. This helps improve energy efficiency, reduce electricity costs, and enhance the performance of electrical equipment.
If the relay is bad, then the fuel pump will not work.
Yes, it is a fuel pump relay.
If the relay has malfunctioned, yes.
The three relays starting from the left are fuel pump relay, horn relay and fog lamp relay (if equipped).
Replace the Flasher Relay.
simply as a relay.
application
The way i understand it is that the relay has the hot and the ground connected and when you press the brake the relay works like a toggle and completes the circuit.
