Scope
1.1
This Standard specifies the requirements for distribution transformers intended primarily for operation by electric utilities.
Note: The operation of transformers complying with this Standard, by other than an electric utility, may be subject to additional requirements by the electrical inspection authority having jurisdiction under Part I of the Canadian Electrical Code.
1.2
This Standard applies to single- and three-phase, 60 Hz, liquid-filled, distribution transformers, Types ONAN and LNAN, rated at 1000 kV·A or below for single-phase and at or below 3000 kV·A for three-phase, insulation class 34.5 kV and less.
1.3
This Standard includes voltage ratings, kV·A ratings, certain mechanical characteristics, and test procedures. Also included are the following performance characteristics: te mperature rise, loading capabilities, sound level, and radio influence voltage (RIV).
1.4
This Standard also applies to self-protected transformers, except for the protective equipment.
1.5
Except as specified by other CSA Standards this Standard does not apply to auto-, testing, dry-type, welding, furnace, rectifier, network, pad-mounted, subway-type, or special-purpose transformers, or to step-voltage regulators.
1.6 Transformers built in accordance with this Standard shall meet the quality requirements of CSA Standard CAN3-Z299.3.
