    Nice Question Raman, No issue at all for replacing silica gel in online. But one think you have to do is, after opening the silica get container, you should close the breather pipe to avoid foreign particle entering into the transformer body.

    Also do not use silica gel More than a year.

    General Replacing Procedure

    • Remove breather safely and close the breather pipe immediately.
    • Spread out the silica gel on a metal place (silica gel seems white colour)
    • heat them well, after increasing the temperature you can find the colour changes from white to blue
    • After completion getting all silica gel from white to blue you can pack them in the same breather and fixed it.
    • Thats all
