Power transformer and reactor fittings -- Part 2: Gas and oil actuated relay for liquid immersed transformers and reactors with conservator
EN 50216-2 covers the gas and oil actuated relay (Buchholz relay) for liquid immersed power transformers and reactors with conservator for indoor or outdoor installation.
The device is intended to detect
– gas release from the unit to be protected,
– oil surge from the tank to the conservator,
– complete loss of oil in the conservator.
This part of EN 50216 defines the
– operating limits,
– dimensions,
– operational performance,
– electrical characteristics,
– dynamic characteristics.
It applies to relays with dry contacts.
It is not applicable to flameproof relays.
Should environmental conditions and dynamic stress requirements differ from those detailed in clause 3 of EN 50216-1, EN 50216-2 may then be applied by agreement between purchaser and supplier for those parts which are not affected by such abnormal installation conditions.
NOTE EN 50216-2 may be used as far as applicable for relays with mercury switches. Restrictions on the use of mercury devices may be imposed by national regulations.
