A transformer used to step up or down the value of voltage.
Moisture entered inside the transformer coil may cause loss of IR value. IR value can be increased by removing the moisture. Keep the transformer in a hot air chamber for sufficient time to vaporize the moisture.
This typically has to do with how many amps you can safely pull from the secondary of the transformer.

A stp-down transformer steps voltage down from a high value to a low value. Transformers only work with AC.
A transformer is used to change the value of a voltage applied to the transformer's primary winding to a different voltage value taken from the transformers secondary winding. A rectifier is used to change an alternating current value to a direct current value.
Transformer
Sir I am Imran khan in nepal my problem is 6000KVA Step down Transformer is not charging. Transformer Pri- 33000V /105A Sec- 6900V / 502Atransformer all test (open & short circuit ) good . but problem is HT(IR)= value this time IR value 50M ohmBefore 3days HT(IR) = value is 7000M ohm suddenly start Transformer result is Transformer not charging & HT(IR) value is down 50M ohm.
An ordinary transformer has two input/output terminals but a center tapped transformer has 2 input and 3 output terminals. One is taken from the center for a ground connection. This causes it to get 50% of the actual value. And ordinary transformer contains 2 windings. An autotransformer has one.
What's the maximum value power capacity of dry type
Like transformer induction motor has stator winding(Primary winding) and rotor winding(Secondary winding) separated by an airgap.Rotor winding(generally Al bars) are short circuited at the end to produce torque for the rotation.Hence the name short circuited transformer.
