Pertinent

Control architecture for high-power electronics from power semiconductor device levels to the power system level is defined and characterized. Coverage includes the application of power electronics in the areas of Power Quality/Custom Power, Flexible AC Transmission Systems (FACTS), High Voltage DC Transmission (HVDC), Distributed Generation, Energy Storage applications, etc. with a power range from hundreds of kW to thousands of MW, but with emphasis on the 1 MW to hundreds of MW.

Description: Terms currently in use in the field of stationary batteries are defined in this standard. This standard does not include terms specific to battery manufacturing activities or to nonstationary battery applications such as motive, portable, marine, or other such applications.

Description: Considered in this guide are the components of both the ac and dc systems and the provided guidelines and recommendations for designing the appropriate systems for the substation under consideration. This guide includes the low-voltage auxiliary systems from the source(s) to the distribution point(s). Reliability requirements and load characteristics are discussed and distribution methods are recommended.

1.1 The requirements in this document evaluate the fire characteristics of a battery energy storage system that undergoes thermal runaway. The data generated will be used to determine the fire and explosion protection required for an installation of a battery energy storage system.

1.1
This Standard applies to ac and dc type power conversion equipment (PCE) that
a) is of dry or liquid-filled construction;
b) has a rated voltage not exceeding 1500 V; and
c) is for commercial, industrial, and residential indoor and outdoor use in nonhazardous locations in accordance with the Rules of the Canadian Electrical Code, Part I.
1.2
Clauses 1 to 6 are general, and apply, unless otherwise noted, to all PCE.

1.1

This Standard applies to exit signs, unit equipment, emergency luminaires, and central power systems intended for connection to circuits with nominal voltages of 600 V and less and providing illumination in the event of a failure of the normal power supply for nonhazardous locations in accordance with the Rules of the Canadian Electrical Code, Part I.



1.2

This Standard includes requirements for the construction of emergency lighting equipment to preclude fire and shock hazards and to ensure that the equipment has the minimum capability for performing its intended function.



1.3

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.



1.4

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.

This International Standard deals with safety aspects of power transformers, power supplies, reactors and similar products such as electrical, thermal and mechanical safety.
This standard covers the following types of dry-type transformers, power supplies, including switch mode power supplies, and reactors, the windings of which may be encapsulated or non-encapsulated :
NOTE 1 The distinction between transformers, power supplies and switch mode power supplies is as follows:

Replacement:
This part 2 of IEC 61558 applies to stationary or portable, single-phase or polyphase, aircooled separating transformers, associated or not, having a rated supply voltage not exceeding 1000 V a.c., a rated frequency not exceeding 500 Hz, and a rated output not exceeding: . 1 kVA for single-phase transformers; . 5 kVA for polyphase transformers.

Replacement:

This International Standard deals with all aspects of safety such as electrical, thermal and mechanical.

This part 2-13 of IEC 61558 applies to stationary or portable, single-phase or polyphase, aircooled (natural or forced), independent or associated auto-transformers, having a rated supply voltage not exceeding 1 000 V a.c., a rated frequency not exceeding 500 Hz.

Replacement:
This part 2-2 of IEC 61558 applies to stationary or portable, single-phase or poly-phases, aircooled control transformers associated or otherwise having a rated supply voltage not exceeding 1 000 V a.c. or 1 415 V ripple free d.c. and rated frequency not exceeding 500 Hz and no limitation of the rated output.
This standard is applicable to transformers used between circuits where double or reinforced insulation is not required by the installation rules or by the equipment specification.
