Yearly maintenance should include blowing out dust and then vacuuming up the dust. While the transformer is down all the bolts and terminations should be checked for tightness. Make sure that the vents in the case are not blocked by foreign objects that happen to be in the same room as the transformer.

What is the maximum value power capacity of dry type transformer?
What's the maximum value power capacity of dry type
What is difference between a wet type and dry type transformer?
Transformer oil is a much better electrical insulator than air. So, in large transformers, oil is used to reduce the flashover distances between live internal parts, thus reducing the overall bulk of the transformer. At the same time, oil helps cool the transformer either by natural convection, or by forced circulation.'Dry transformers' are transformer that do not use oil for insulation or cooling purposes. They tend to be transformers with lower voltage and power ratings, where flashover and cooling is far less relevant.
Is dry type transformer air conditioned?
To my knowledge no transformer is air conditioned. Some transformers have fans mounted on them, however, for uprating purposes. I don't believe this is an effective cooling mechanism for dry type transformers either (fans are usually used on oil filled transformers).
What should be the transformer to building separation distance for fire suppression?
Depends on size of transformer and type (dry,mineral oil, silicone) as well as ground slope and building construction.
What type of transformer used in bed lamps?
If the bed lamps use a low voltage bulb then the type of transformer will be a step down transformer.
What are the disadvantage and advantage of dry type transformer?
Advantages dry type transformer accommodates less place than any other. this x'mer do not catches a fire. instalation at any place is convenient. eco friendly looks & use internal inspection is possible. no corrosion. side clearance is less maintenance free (easy) disadvantages can not be use for more than 2000KVA

Can Dry Type step down Transformer be put out door?
It is not a good idea to place an indoor, dry type transformer in out door. In outdoor it may subject to rain etc, for which it may not have been designed to.
What type of cooling is used in dry atmospheres in transformer?
forced air and draft oil dissipate
Is site selection necessary for dry type transformer?
Necessary? Probably not. A good idea? Probably.

Why is a core type transformer mostly used in three phase inverters?
A dry type using air to cool instead of oil.
Why partial discharge test in dry type transformer?
to check if any air voids are present in casting
What is a dry-type transformer?
Electric company high voltage transformers used in the utility grid are typically insulated by being immersed in a tank of oil, and cooled by natural convection (circulation) of the oil. A "dry type" transformer is not immersed in oil, and is cooled by air convection or by fans.
