EN 50216-3 applies to protective relays for hermetically liquid-immersed transformers, complying with the EN 60076 series, and reactors, complying with EN 60289, without gaseous cushions for indoor or outdoor installation.
This part of EN 50216 defines the
– operating limits,
– outline and mounting details,
– operational performance,
– electrical characteristics,
– dynamic characteristics.
Should environmental conditions and dynamic stress requirements differ from those detailed in clause 3 of EN 50216-1, EN 50216-3 may then be applied by agreement between purchaser and supplier for those parts which are not affected by such abnormal installation conditions.
NOTE EN 50216-3 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.
