BS EN IEC 60076‑22‑6 covers the electric fans used in the cooling circuits of power transformers and reactors. It applies to electric fans mounted on liquid immersed power transformers and reactors with and without a conservator for indoor or outdoor installation.
BS EN IEC 60076‑22‑6 outlines the operation requirements specific to each equipment as well as the preferred dimensions relevant for interchangeability and uniform fan assembly and the type and routine tests to be performed.
NOTE 1: The electric fans concerned by BS EN IEC 60076‑22‑6 are of the axially operating type and are for use on liquid to air coolers and for blowing out radiators.
BS EN IEC 60076‑22‑6 on electric fans for transformers is useful for:
BS EN IEC 60076‑22‑6 specifies the technical terms and specifications such as service conditions and general characteristics and requirements for electric fans so that you can manufacture electric fans that are in compliance with standard transformers.
BS EN IEC 60076‑22‑6 provides you with important aspects regarding the performance of a transformer fan and procedures to carry out various tests like type tests and routine tests so that transformer maintenance can be done easily.
