A Buchholz relay is located in an inclined pipe between a tranformer's tank and its expansion tank. It has two purposes: (1) to set off an alarm in the event of a loss of oil or the formation of an excessive amount of gas bubbles (likely caused by minor arcing between the turns of a winding), and (2) to disconnect the transformer in the event of a continued loss of oil, or a catastrophic fault within the transformer.

Why the arrow direction marked on top of the bucholz relay on power transformer?
The indicates the direction for correct installation. Bucholz relay operates when gas bubbles in the transformer oil pass through the relay in its pathway. The relay has to be installed arrow indicating upwards.
Why buchholz relay is used in transformer have ratings more than 750kva?
Buchholz Relay is a special type of relay and its only used in transformers, and the main use of this relay is transmission and distribution systemAnswerA Buchholz relay is used between a transformer and its expansion tank. So they are only used (1) where there is an expansion tank and, (2) in substations, where the associated protection relays can be installed.
What is a function of a Buchholz relay?
A Buchholz relay is designed to detect a failing oil-filled power transformer. It will automatically disconnect the transformer and produce an alarm signal.
What effect of an electric current does a relay and transformer use?

How you using ref relay in transformer?
an REF relay (restricted earth fault) is used to provide ground fault protection for a transformer. Its' operation is limited by CTs starred towards the transformer (usually on the transformer bushings or in breakers used to isolate the transformer), so it will only operate for transformer related faults. Because of this, it can be set to operate very quickly.

Why the arrow direction marked on top of the bucholz relay on power transformer?
The indicates the direction for correct installation. Bucholz relay operates when gas bubbles in the transformer oil pass through the relay in its pathway. The relay has to be installed arrow indicating upwards.
What is bucholz protection?
A Bucholz relay is also known as a sudden pressure relay. In high voltage transformers, if a turn to turn fault develops, this will result in a rapid rise in pressure inside the transformer tank due to localized heating. A Bucholz relay is designed to sense this rapid change in pressure, and can be used to alarm or trip the transformer off line. These are also used on large reactors. Since these are a mechanical device, they can be sensitive to vibrations, so they may not be enabled for tripping in locations very near train tracks or fault lines.
