It is necessary to measure the insulation absorption ratio of transformer when maintaining and protecting transformer, it is equal to the ratio of the insulation resistance measured in 60 seconds to the insulation resistance measured in 15 seconds, that is R60/B15. The absorption ratio can be used to determine if the insulation is wet, dirty or partially defective, 35 ~ 60 KV winding is not less than 1.2,110 ~ 330 kv winding is not less than 1.3.
