CSA - CAN/CSA-C2-M91

Single-Phase and Three-Phase Distribution Transformers, Types ONAN and LNAN

inactive, Most Current
Organization: CSA
Publication Date: 1 January 1991
Status: inactive
Page Count: 51
scope:

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.

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.

This Standard includes voltage ratings, kV·A ratings, certain mechanical characteristics, and test procedures. Also included are the following performance characteristics: temperature rise, loading capabilities, sound level, and radio influence voltage (RIV).

This Standard also applies to self-protected transformers, except for the protective equipment. 

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. 

 Transformers built in accordance with this Standard shall meet the quality requirements of CSA Standard CAN3-Z299.3.
