This is the second edition of CSA C22.2 No. 190, Capacitors for power factor correction, one of a series of Standards issued by CSA Group under Part II of the Canadian Electrical Code. It supersedes the first edition published in 1985.

Changes to this edition include the insertion of Update 1 (December 1985) and Update 2 (January 1988) and the addition of Clause 10, and Tables 7, 8, 9, and 10.

For general information on the Standards of the Canadian Electrical Code, Part II, see the preface of CAN/CSA-C22.2 No. 0.

This Standard is considered suitable for conformity assessment within the stated scope of the Standard.


This Standard applies to indoor or outdoor, open or enclosed, shunt power capacitors and assemblies of shunt power capacitors with associated interconnections and supporting structures, for power factor improvement and other applications on ac power systems having voltages up to 46 kV, designed to be installed in accordance with the Rules of the Canadian Electrical Code, Part I.

The requirements of this Standard also apply to self-healing capacitor with metallized electrode for use on ac systems having a maximum voltage between phases of 1000 V and less.

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.
