scope:

This Standard, except as noted in Clause 1.2, applies to all liquid-filled transformers, autotransformers, booster transformers, load-tap-changing transformers, grounding transformers, phase-shifting transformers, series-voltage regulators, and shunt reactors.

Note: The term "transformer(s)" in this Standard refers to the overall unit and not just to the electrical components implied by the definition.

This Standard does not apply to the following:

a) distribution transformers (see CAN/CSA-C2.1 and CAN/CSA-C2.2);

b) instrument transformers (see CAN/CSA-C60044 series and CAN/CSA-C61869 series);

c) dry-type transformers (see CSA C9);

d) pad-mounted transformers (see CAN/CSA-C227 Series of Standards);

e) submersible transformers (see CSA C301 Series of Standards);

f) three-phase network transformers (see CSA C199); and

g) rectifier transformers, welding transformers, furnace transformers, starting transformers, testing transformers, or current-limiting reactors.

Note: In the above list, the pertinent CSA Group standard number has been noted where such exists. Where no CSA Group standard exists, this Standard may be used insofar as it applies.

This Standard does not include energy efficiency requirements. For such requirements, see CSA C802.3 for maximum losses for power transformers up to 10 MVA.

The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.

In this Standard, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; "should" is used to express a recommendation or that which is advised but not required; and "may" is used to express an option or that which is permissible within the limits of the Standard.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
