Control System

The standard is intended to be a basic functional safety standard applicable to all kinds of industry. It defines functional safety as: “part of the overall safety relating to the equipment under control (EUC) and the EUC control system which depends on the correct functioning of the E/E/PE safety-related systems, other technology safety-related systems and external risk reduction facilities.”

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).

The standard sets out requirements for the design, construction and verification of electrical installations, including the selection and installation of electrical equipment forming part of such electrical installations. These requirements are intended to protect persons, livestock, and property from electric shock, fire and physical injury hazards that may arise from an electrical installation that is used with reasonable care and with due regard to the intended purpose of the electrical installation.

Applicable to substation automation systems: defines communication between intelligent electronic devices in substation and system requirements; provides overview of standard series; refers to text and figures from other parts of IEC 61850 series.

The standard covers electrical, dimensional, and mechanical characteristics, taking into consideration certain safety features, for current and inductively coupled voltage transformers of types generally used in the measurement of electricity and the control of equipment associated with the generation, transmission, and distribution of alternating current. The aim is to provide a basis for performance, interchangeability, and safety of equipment covered and to assist in the proper selection of such equipment. Accuracy classes for metering service are provided.

The document presents general requirements that Telcordia and participating industry representatives view as applicable to large format non-aqueous rechargeable lithium batteries to replace or interoperate with conventional batteries (i.e., Lead-Acid, nickel-based); function seamlessly with DC power plants; and provide reliable backup power to load equipment in a network environment of a typical telecommunications service provider.

Intended Use
The objective of Standards issued as part of the Canadian Electrical Code, Part II, is to give consideration to the prevention of injury to persons and damage to property through proper design, good construction, and high quality of work. These safety Standards are intended to provide requirements for the design and construction of electrical equipment, primarily to address fire and electrical shock hazards and for use throughout Canada in conformity with the rules of the Canadian Electrical Code, Part I.

This Technical Report covers the opportunity charging of lead-acid traction batteries, i.e. the use of free time during a working period to top up the charge and thus extend the working day of a battery whilst avoiding excessive discharge. The object of this report is to lay down rules or recommendations for the use of opportunity- charging of lead-acid traction batteries of vented and valve-regulated types, when the battery manufacturer has not recommended the required operating procedures.

This is an informative document covering the broadest aspects of automatic monitor systems as they apply to traction battery applications. The subject of the guide covers those monitor characteristics and features which need to be controlled, though not necessarily currently available. In addition it accommodates those characteristics which are measurable and provides interpretations of accuracy and reliability of the information generated. This publication has the status of a Technical Report - type 3

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.
