1 Scope
EN 50216-11 covers oil temperature and winding temperature (thermal image) indicators of the
interchangeable mechanical (not electronic) type with contacts for use with liquid immersed power
transformers and reactors for indoor or outdoor installation.
This standard defines the characteristics of the instruments in order to ensure the interchangeability
achieving the same performance.
Except where otherwise specified or implied herein, oil and winding temperature indicators shall comply
with the requirements of EN 50216-1.
