Can loose neutral wire effect the operation of Earth Leakage Circuit Breaker?
Yes, a loose neutral wire can effect the operation of Earth Leakage Circuit Breaker.
What is leakage resistance in RC circuit?
Leakage resistance in any circuit is resistance less than infinity where it is not expected, such as across an insulator. In the ideal sense, all circuits have leakage resistance because no insulator is perfect, but we usually ignore this except in special situations because it does not normally matter in real applications. In an RC circuit, leakage resistance would most typically be across the capacitor.
When emitter is open and the collector junction is reverse biased still a very small current flows in the circuit why?
Most transistors and diodes exhibit reverse bias leakage.
What is function of snubber circuit?
capable of resetting the transformer as well as eliminating leakage inductance voltage spike across the switch
What is seat leakage test in safety valves?
Seat leakage is defined as leakage that is internal to a valve-between the inlet and outlet sides of the valve-when the valve is in its closed position. It is not limited to leakage across the valve seat, but also encompasses all leakage across the valve trim when the valve is in the closed position. Leakage across internal trim seals, such as piston rings, and across trim-to-body seals, such as gaskets, can be counted as seat leakage. It is important to note that, while leakage through valve stem packing is of growing concern in the industry, governing industry standards address this type of leakage separately and do not consider it to be a form of seat leakage.
Why leakage flux in transformer equivalent circuit is modeled as an inductor?
Because some of the primary flux fails to link with its own winding, the back- e.m.f. induced into the primary winding will be slightly lower than it would be had there been no leakage at all. We can account for this 'loss' of induced voltage as though it were caused by a small voltage drop occurring in the primary circuit, due to a small inductive-reactance connected in series with the primary winding. We call this the 'primary leakage reactance' (Xp).A similar explanation can be applied to the secondary circuit, thus giving the secondary circuit a 'secondary leakage reactance' (Xs).
Can loose neutral wire effect the operation of Earth Leakage Circuit Breaker?
Yes, a loose neutral wire can effect the operation of Earth Leakage Circuit Breaker.

What flux that does not follow the intended path in a magnetic circuit?
leakage flux
Draw and explain the operation of fault voltage ELCB and residual current device?
ELCB means Earth Leakage Circuit Breaker -- it is used to trip the Circuit breaker if any leakage fault occured means
What are three sources of power for control circuit?
The Three sources of power for control circuit are dynamic power, short-circuit power and leakage power.
How do you express an earth leakage circuit breaker?
In North America they are known as a GFCI. Ground Fault Circuit Interrupter breaker.
Is corrosion in a circuit result in a direct current flow?
As the circuit collects moisture and dirt leakage path are formed around the paths causing eventual circuit failures
How do you solve earth leakage?
The best way to stop earth leakage is to make sure that the are no active circuits going to ground. This will help keep the circuit running right.
What is the minimum value of current to trip the Earth leakage circuit breaker?
30 m amp
What is the definition of the consumer circuit in electrical installation?
Consumer circuit is a circuit that fixed between distribution line and consumer load control and protection unit is attached in order to prevent overload, leakage and short circuit.
What is leakage voltage?
There is no such thing.What there is is leakage current, which is the amount of undesired current flow in a branch of an actual circuit when that branch of the equivalent ideal circuit would have no current flow.Leakage current can also be used to refer to current that occurs on a path where there is no intentional circuit branch (e.g. corona discharge current to the air in a high voltage system).
