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:)
Yes, it possible to do a short circuit test of breakers at a project site.
Open circuit and short circuit tests are performed to determine transformer characteristics. In the case of a single phase transformer, SC tests would be performed to determine the impedance. The open circuit test will give excitation information (% excitation at specific voltages, often 90%, 100% and 110%, and no load losses).
A short circuit is generally more dangerous than an open circuit because it allows a current to flow through an unintended path, leading to overheating, fires, and potential damage to electrical components. An open circuit, on the other hand, simply means that the circuit is incomplete and no current can flow, which may simply result in a non-functioning device.
An open circuit occurs when there is a break in the electrical path, cutting off the flow of current. When a hot wire touches ground, it can create a short circuit where current flows directly to ground instead of through the intended circuit, leading to potential danger and damage to the equipment.
meaning that the current from your power source doesn't return to the positive end (electricity flows from - negative, to + positive)
Short circuit test and open circuit test are widely used to test the efficiency of the transformer.
The open/short-circuit test on a transformer isn't 'needed'. It's only used if you want to find out the efficiency of a transformer.
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
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)
An open circuit or a short-circuit (if that circuit is complete).
open circuit & short circuit test, insulation resistance test, turns ratio, efficiency, if it is oil cooled then breakdown voltage of oil, voltage regulation and definitely visual inpection...
in the short circuit test we applied supply voltage on L.V side and short circuit the H.V side and connect the ammeter in H.V circuit to measure the short circuit current. with the help of s.c test we measure the copper losses in the transformers.

In Short circuit test High Voltage side is feeded with 2-5% of the High Voltage rating to circulate approximately full load current in low voltage winding by short circuiting it. Low voltage is generally short circuited to facilitate measurements because it is more difficult to measure the quantities at high voltages.
In DC inductor is short circuited .
To test for a short circuit in a circuit, you can use a multimeter set to measure resistance. Disconnect the power source, then place the multimeter probes at different points in the circuit. If the resistance reading is very low or zero, it indicates a short circuit.
an open circuit is a circuit that does not complete the circle. an open circuit does not do the job as the electricity stands still a short circuit is a circuit that wires have crossed and the electricity takes the shortest path. and does not complete all of the points on the circuit
