Power Emergency Equipment

The scope of this document is to provide guidelines for consistant and standard applications for voltage and power quality requirements on or connected to HOL’s distribution system. Normally voltage limits, voltage distortion, and current distortion are measured at the customer’s Point of Supply as per HOL document ECS0012. This document does not cover the following power quality issues: • Voltage control when the Independent Electrical System Operator (IESO) has declared a voltage reduction or an electrical system emergency; • Non-standard conditions such as a force majeure (e.g.

Readiness of emergency power is a key consideration in safeguarding building occupants in the event of a disruption of the normal utility supply. NFPA 111 covers performance requirements for stored electric energy systems providing an alternate source of electrical power in buildings and facilities during interruption of the normal power source.

Scope – Clear definition of what is/is not covered by the standard (e.g., power, voltage, other criteria).

1.1 This Standard applies to emergency lighting and power equipment for use in unclassified locations and intended for connection to branch circuits 600 V or less. Intended to supply illumination, power or both automatically to critical areas and equipment in the event of failure of normal supply in accordance with NEC Article 700 or 701, NFPA 70, Life Safety Code, NFPA 101, Fire Code, NFPA 1, International Building Code (IBC) and International Fire Code (IFC).

Applies to all stationary Lead-Acid cells and monobloc batteries of the valve regulated type for float charge applications (i.e., permanently connected to a load and to a DC power supply), in a static location and incorporated into stationary equipment or installed in battery rooms for use in telecom, UPS, utility switching, emergency power or similar applications. The objective is to specify test methods for all types and construction of valve regulated stationary Lead-Acid cells and monobloc batteries used in standby power applications.

1.1 This Standard applies to uninterruptible power supplies (UPS). The primary function of the UPS covered by this Standard is to ensure continuity of an alternating power source. The uninterruptible power supplies can also serve to improve the quality of the power source by keeping it within specified characteristics. 1.2 This Standard is applicable to movable, stationary, fixed, and built-in UPS for distribution systems up to and including 600 V ac.

Replace this clause of the RD with the following: 1.1.1 Equipment covered by this standard This Standard applies to UPS, whose primary function for this Standard is to ensure continuity of an alternating power source. The UPS may also serve to improve the quality of the power source by keeping it within specified characteristics. This Standard is applicable to movable, stationary, fixed, and built-in UPS for distribution systems up to 600 V AC.

This standard covers performance requirements for emergency and standby power systems providing an alternate source of electrical power in buildings and facilities in the event that the normal electrical power source fails. Systems include power sources, transfer equipment, controls, supervisory equipment, and accessory equipment needed to supply electrical power to the selected circuits.

IEC 61056-1:2012 specifies the general requirements, functional characteristics and methods of test for all general purpose lead-acid cells and batteries of the valve-regulated type:
 - for either cyclic or float charge application;
 - in portable equipment, for instance, incorporated in tools, toys, or in static emergency, or uninterruptible power supply and general power supplies.
