A pressure-relief device shall be supplied on tanks and liquid-
filled compartments that are subjected to pressure in the event
of abnormal or fault conditions (such as an arcing fault). This
device may be a pressure-relief vent for use on transformers
equipped with a conservator tank or a self-resealing
mechanical relief device. The design of the device shall reduce
the risk of the continued flow of liquid following its operation.
The pressure-relief device shall have a hood or be directed, or
both, so that any liquid discharged will be directed downwards
and away from the operational controls. The opening pressure
of the pressure-relief means shall be less than the withstand
pressure of the tank structure.
Note: The objective of the pressure-relief device is to prevent or
at least minimize tank or compartment rupture in the event of
an internal fault.

Grounding
P
A suitably sized ground stud shall be provided on the outside of
the enclosure. In the case of transformers, the transformer core
shall be grounded internally to the tank.
