why bucholtz relay placed inclined in transformer?..

Answer / engr. l. o. osuji

The bulb of the Buchholz relay contains liquid mercury which
closes the alarm or alarm/trip contacts whenever the relay
is activated. Note that the liquid mercury closes the
alarm contacts only if the gas flow through the relay is
not serious. However, if the flow is serious both alarm and
trip contacts will close to give alarm and trip signals.
From the above explanation you can understand that liquid
mercury being a good conductor must be kept away from the
contacts under normal condition. The only way to do this is
by tilting the relay.
