Pertinent

This Recommended Practice encompasses the monitoring of electrical characteristics of single-phase and polyphase ac power systems. It includes consistent descriptions of conducted electromagnetic phenomena occurring on power systems. The document describes nominal conditions and deviations from these nominal conditions that may originate within the source of supply or load equipment, or from interactions between the source and the load. Also, this document discusses power quality monitoring devices, application techniques, and interpretation of monitoring results.

This part of IEC 62109 applies to the power conversion equipment (PCE) for use in Photovoltaic (PV) systems where a uniform technical level with respect to safety is necessary. This standard defines the minimum requirements for the design and manufacture of PCE for protection against electric shock, energy, fire, mechanical and other hazards. This standard provides general requirements applicable to all types of PV PCE. There are additional parts of this standard that provide specific requirements for the different types of power converters, such as Part 2 - inverters. Additional parts may be published as new products and technologies are commercialised. This standard covers PCE connected to systems not exceeding maximum PV source circuit voltage of 1 500 V d.c. The equipment may also be connected to systems not exceeding 1 000 V a.c. at the a.c. mains circuits, non-mains a.c. load circuits, and to other DC source or load circuits such as batteries. This standard may be used for accessories for use with PCE, except where more appropriate standards exist. Evaluation of PCE to this standard includes evaluation of all features and functions incorporated in or available for the PCE, or referred to in the documentation provided with the PCE, if such features or functions can affect compliance with the requirements of this standard. Replace the maximum PV source circuit voltage of 1 500 V d.c. with 2 000 V d.c. This standard has not been written to address characteristics of power sources other than photovoltaic systems, such as wind turbines, fuel cells, rotating machine sources, etc. NOTE 1 Requirements for other sources may be incorporated in the IEC 62109 series in the future. Additional or other requirements are necessary for equipment intended for use in explosive atmospheres (see IEC 60079), aircraft, marine installations, electromedical applications (see IEC 60601) or at elevations above 2 000 m. NOTE 2 Requirements are included for adjustment of clearance distances for higher elevations, but not for other factors related to elevation, such as thermal considerations Add new sentence before NOTE 1. "PV PCE with inputs for other non-PV power sources (not specifically addressed by this standard), shall address the normal and abnormal source specific operating characteristics including but not limited to; voltage range, current range, short circuit current, over-voltage, etc." The purpose of the requirements of this part of IEC 62109 is to ensure that the design and methods of construction used provide adequate protection for the operator and the surrounding area against: a) electric shock and energy hazards; b) mechanical hazards; c) excessive temperature hazards; d) spread of fire from the equipment; e) chemical hazards; f) sonic pressure hazards; g) liberated fluids, gases and explosion hazards. NOTE Servicing personnel are expected to have the necessary knowledge and skill to use reasonable care in dealing with hazards associated with the operation, repair and maintenance of this equipment. Based upon this premise, this standard provides only limited requirements (for example markings or guarding) intended to protect service personnel from hazards that may not be apparent even to trained personnel. Aspects not covered by this standard include, but are not limited to, the following: a) functional reliability, performance or other properties of the equipment not related to safety; b) effectiveness of transport packaging; c) EMC requirements; d) installation requirements, which are covered by local and national installation codes. NOTE This standard does provide requirements for PCE intended to ensure that the PCE can be installed in a safe manner, including requirements for installation instructions provided with the product.

The technical requirements for parallel generation are in place to ensure public and employee safety, protect the integrity of Toronto Hydro’s system, and guarantee reliable and quality service to Toronto Hydro customers. The technical requirements in this document are for the protection of Toronto Hydro's facilities, and the Generator should satisfy itself as to any requirements for the protection of its own facilities.

This Code sets the minimum conditions that a distributor must meet in carrying out its obligations to distribute electricity under its licence and the Energy Competition Act, 1998. Unless otherwise stated in the licence or Code, these conditions apply to all transactions and interactions between a distributor and all retailers, generators, distributors, transmitters and consumers of electricity who use the distributor’s distribution system.

This standard is intended for distributor personnel in charge of integrating distributed generation into the distribution system. It is also intended for power producers with generating stations connected to the Hydro-Québec MV distribution system. They are required to comply with this standard.

The National Building Code of Canada 2015 (NBC), published by NRC and developed by the Canadian Commission on Building and Fire Codes, sets out technical provisions for the design and construction of new buildings. It also applies to the alteration, change of use and demolition of existing buildings. Over 360 technical changes have been incorporated in this new edition.

1. The object of this Act is the protection of persons and property, except forest resources which are protected pursuant to the Sustainable Forest Development Act (chapter A-18.1), against fires of any nature. For the purposes of this Act, any explosion likely to cause a fire shall be considered to be a fire. 2000, c. 20, s. 1; 2010, c. 3, s. 329. 2. This Act does not operate to limit the obligations imposed or powers granted by or under other Acts as regards fire safety. 2000, c. 20, s. 2; 2001, c. 76, s. 153. 3.
