The general answer is that a continuity tester is used to check for an open circuit.

Short circuit test and open circuit test are widely used to test the efficiency of the transformer.


What would the results of voltage drop test be if the circuit is open?

voltage drop is zero bcz in open ckt current will be zero


Open circuit and short circuit test?

Open circuit means the circuit is not continuous . A short circuit is continuous but has a fault connecting between either live to neutral or earth .As result of this we saw that this answer is unsufficent to explain short and open circuit on the other hand you can use this answer also like i did:)

Why you Removal of lamps from lighting outlet points When carrying out an insulation resistance test on this installation?

I'm not sure exactly what you're asking, but it sounds like you are wanting to test for any potential weak spots in insulation which would allow for stray current to pass through. You would want to set the circuit so that it would be an open circuit, so that if it was truly an open circuit, no current would be flowing through the circuit, where if some breakdown in the insulation allowed for a current flow, then you would be able to detect it.


What does reading of wattmeter indicate in case of open circuit test of transformer?

In case of open circuit test of transformers we measure iron losses and hence the power lost here is being measured by the wattmeter.


Why do you start with open circuit test?

i hope this may be correct answer but iam not sure this is because if the short circuit test is performed first, because of induction effect some amount of energy is stored in the transformer or motor and while performing the open circuit test there may be a chance of getting error bcz of stored charge as in open circuit test the amount of current is vvv less wnen compared to short ckt by sandeepraj patnala


Why low power factor wattmeter is used for open circuit test of transformer?

For open circuit test of transformer, the secondary is open circuit and the circuit impedance is largely inductive due to the core impedance having high L as compared to R. hence the power factor is reduced, thus , we use low power factor wattmeters.


Why open circuit test on rated voltage?

What is the purpose of open circuit test and short circuit test of a transformer?

An open-circuit test is done with the transformer running at its rated voltage but with no load. This measures the power lost in the magnetic core. (IR Losses) A short-circuit test is done with the transformer running at its full rated current in all windings but at a low voltage. The secondary is shorted and the primary voltage is adjusted to give the rated current. This measures the power lost in the copper windings. (Copper losses)


Why is it assumed that during open circuit all the losses are core losses?

Since this is an open circuit test, there is no load attached, thus all losses must be internal to the transformer.


How do you test a closed circuit?

we can make an open circuit by disconnecting the wire or break the circuit and a closed circuit is made by connecting all wires with the contents of the circuits.
