CSA Standards

Power Transformers and Reactors - Fifth Edition
 N C88-16

Annotation

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.
