Scope

This clause of GB 19212.1-2008 is replaced by the following:
This part deals with the safety of isolating transformers for general applications and
power supply units incorporating isolating transformers for general applications.
Transformers incorporating electronic circuits are also covered by this standard.
NOTE 1: Safety includes electrical, thermal and mechanical aspects.
Unless otherwise specified, from here onward, the term transformer covers isolating
transformers for general applications and power supply units incorporating isolating
transformers for general applications.
NOTE 2: For power supply units (linear), this part is applicable. For switch mode
power supply units, IEC 61558-2-16 is applicable together with this part.
This part is applicable to stationary or portable, single-phase or polyphase, air-cooled
(natural or forced) independent or associated dry-type transformers. The windings may
be encapsulated or non-encapsulated.
The rated supply voltage does not exceed 1 100 V a.c., and the rated supply frequency
and the internal operating frequencies do not exceed 500 Hz.
The rated output does not exceed:
-- 25 kVA for single-phase transformers;
-- 40 kVA for polyphase transformers.
This part is applicable to transformers without limitation of the rated output subject to
an agreement between the purchaser and the manufacturer.
NOTE 3: Transformers intended to supply distribution networks are not included in the
scope.
