Pumping means if breaker is close & give close command (electrical or manual) to it,spring will discharge & charge again. To prevent this pumping anti pumping feature is required,which in turn will help to restrict unnecessary operations of breaker mechanisms.

What is function of damping relay in circuit breaker?
The anti-pumping relay is a device in circuit-breaker whose function is to prevent multiple breaker closures. For instance, if the operator gives the closing command to the breaker by pressing the close button and the breaker closes. However, a fault in the system causes the breaker to trip. Since the close command is still in the pressed condition, there is a chance of the breaker closing again and being tripped by the relay multiple times. This can damage the closing mechanism of the breaker. The anti-pumping relay prevents this by ensuring that the breaker closes only once for one close command from the control panel.
What is operation of an antihunting relay in circuit breaker?
This is also called anti pumping relay. for understanding you have to understand the working of breaker. positive extends to "Low Pressure Lockout" & "Low Pressure Alarm". after maintain the pressure in breaker these NO becomes NC and when breaker closes the auxiliary of breaker get closed and simultaneously extend the positive to the antipumping relay coil by auxiliary contact. by this coil get energised and holding contact get connected and the one of the contact of antipumping coil (NC) become NO which disconnect the command supply of main breaker. by this till when the antipumping relay get energised no further command (+ve) extends to breaker closing coil. This is Antipumping/ Antihunting Relay.
What is switch gear and what is anti slam of circuit breaker?
Switch gear is the service equipment for large buildings. It can range from the size of a closet to enough to fill multiple rooms. You might think of your home service panel as switch gear, though it would never be called that. It serves the same purpose; your home is just not a big as the factory across town. The power coming in is broken down into smaller and smaller equipment until you have a panel a lot like your home service panel to provide power to a section of the building. I do not know what anti slam is. I even looked it up but couldn't find it.
What are numerical relays?
As we know numerical relays use DIGITAL SIGNAL PROCESSOR as its computational hardware and based on microprocessor. WORKING: Analog input is feed into the anti aliasing filter which is a low pass filter.Output of this filter is feed into the sample and hold circuit , frequency of sampling should be twice of our highest frequency of interest(according to the nyquist criterion).if sampling frequency kept low than aliasing input may occur. after the sampling, signal are feed into the multiplexer,where all the signal get multiplexed and we have a single signal.this signal is feed into the analog to digital converter.this digital signal is feed into the microprocessor and microprocessor generates control signal according to its input. for example if you are using N.R. for over-current protection than you should set a value of current in your program.if the value of current passes through the circuit is greater than the set value..than N.R. enables the circuit breaker and hence our system is protected..
What is anti-dependence?
Statement S2 is anti-dependent on statement S1 if S2 follows S1 in program order and if the output of S2 overlaps the input of S1. The anti-dependence S1 to S2 define as cross arrow such as S1 |-> S2.
What is the anti-pumping scheme of Circuit breaker?
in order to stop the repetitive closure of the circuit breakers, anti pumping relay scheme is used. i.e suppose that an operator gives a close command to the breaker(via some switch), now the fault occurs, the breaker would tend to clear the fault and open the contacts.But since the operator has given the close command, it would cause closing of breaker again and again.. so anti pumping relay is used to ensure that this does not happen!

What is a abs relay?
Abs relay is a switch that allows a small current flow in a circuit to a height control circuit for the functioning of the anti lock braking system.
In a vehicle equipped with Anti-Lock Brakes pumping the brakes will?
Be pointless. The point of anti-lock brakes it to effectively "pump" the brakes for you.

When skidding should you apply a quick motion pumping to your brake?
No, if your car has ABS (Anti-lock Braking System) do not pump your brakes. The anti lock system does this for you.

How does MCCB circuit breaker work?
A Miniature Circuit Breaker or "MCB" works as a normal electrical circuit breaker but is a much smaller device. As well as electro-mechanical relay technology it includes electronic circuitry to achieve its small overall size. MCBs are now used extensively for consumer power-distribution panels and inside small electrical equipment.For more information see the answers to the Related Questions and also the Related link shown below.
1996 jetta anti theft malfuction due to blowen fuse?
Fuses That "Blow" RepeatedlyWithout being able to "hands on" troubleshoot the circuit served by the repeatedly blowing fuse, no one can identify the specific cause/defect which is causing your problem.The following generic answer applies to any electrical circuit, whether in a vehicle, or in a building, or whether alternating current [AC] or direct current [DC].Fuses [and Circuit Breakers] are safety devices designed and installed in electrical circuits TO PROTECT the conductors [wires] and other components from short circuit conditions and/or overload conditions which cause an extremely large flow of electrical current [measured in Amperes], which causes overheating of the conductors that results in damage to the insulation and the conductors. And in a worst case scenario, the probability of a FIRE which could destroy the vehicle, house, or other structure in which the circuit is located.When a fuse or Circuit Breaker [and replacement fuses, or "tripping" Circuit Breakers] "blow," especially if it happens repeatedly, is an indication of an UNSAFE CONDITION in that circuit, usually a short.The fuse or circuit breaker is doing what it was designed, intended, and installed to do, protect the conductors and components of the circuit which it serves.The proper "fix" is for a qualified technician, who knows what he or she is doing, to troubleshoot the involved circuit, find and identify the defect, and make proper repair [s], BEFORE replacing the fuse again [with the properly sized fuse or before resetting a circuit breaker].Some ignorant few will suggest installing a larger fuse or breaker to solve the problem, BUT that will only increase the hazard, not correct it. Do not follow "bad" advice by installing a larger fuse in a misguided attempt to correct the problem. To install an over-sized fuse would almost guarantee damage to the wiring and an electrical system fire.
