AL means transformer core property
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.
Transformer
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.
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.
What's the maximum value power capacity of dry type
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.
It shows the Purification during the filtration of crude oil.
The BDV value of the transformer oil should be above 50kv winding resistance value should me minimum depends upon the KVA Of trans earthing should be provide for the trans air should be release inside of the tranformer insulation level should be check to operate the transformer these are all the initial condition to operate the trans
