EN 50216-2:2002

EN 50216-2:2002 is a standard published by CLC. Its full title is "Power transformer and reactor fittings - Part 2: Gas and oil actuated relay for liquid immersed transformers and reactors with conservator". This standard covers: 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.
