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.
A transformer used to step up or down the value of voltage.
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.

yes, we can incease voltage level by aplifiers.......
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.
PI stands for polarization index. We need to find IR value(IR1) for 1min and again find the IR value(IR2) for 10min. PI=IR2/IR1
AL means transformer core property

There are well over a 100 meanings for the abbreviation IR: in some cases a zero value makes no sense but in many it does. Without further information, therefore, it is not possible to answer the question.
