There are several mechanical protection relays installed on the power transformer.
Almost the operation of these relays is instantaneously (no time delay).
As a target of this study, buchholz relay, winding temperature indicator,oil temperature indicator, and pressure relief are explained by their mechanical operation, and electrical circuit needed for alarm and tripping circuits.
