CSA/CAN3 C235-1983 (R2015)
CAN3-C235-83 (R2015) - Preferred Voltage Levels for AC Systems, 0 to 50 000 V
Intended Use
C235 establishes standard distribution and utilization nominal voltages for AC systems up to 50,000 V. This standard specifies the normal and extreme range of voltage variation that should be expected at service entrances and points of electricity utilization. The standard voltages and range of voltage variation are relevant to the design of a variety of residential, commercial and industrial electrical products.
1. Scope
1.1 This Standard establishes voltage standards for AC Systems in Canada to provide a guide:(a) To national committees on utilization and control equipment or devices for establishing standard ratings of such equipment or devices on a basis coordinated with standard systems;
(b) To system designers so that new systems will be designed to accommodate standard ratings of equipment and devices;
(c) To system operators and to electrical energy users for determining the need for corrective measures, with respect to existing systems, to accommodate current designs of equipment and devic es; and
(d) Towards a uniform system of voltage selections in the country without any suggestion that each utility will supply every voltage listed. The establishment of standards on this basis is aimed at future development towards more uniformity on a national basis.
