Specifications

These requirements cover bidirectional electric vehicle charging equipment that charge electric vehicles from an electric power system and also include functionality to export power from the electric vehicle to an electric power system. When commanded, the bidirectional charging equipment exports electric power from the electric vehicle stored energy supply to the electric power system (EPS) to supply power to common loads.

This International Standard specifies requirements and tests for the safe operation of portable sealed secondary cells and batteries (other than button) containing alkaline or other non-acid electrolyte, under intended use and reasonably foreseeable misuse

IEC TR 61850-7-500:2017(E) describes the use of the information model for devices and functions of IEC 61850 in applications in substation automation systems, but it may also be used as informative input for the modeling of any other application domain. In particular, it describes the use of compatible logical node names and data objects names for communication between Intelligent Electronic Devices (IED) for use cases. This includes the relationship between Logical Nodes and Data Objects for the given use cases.

1.1 Scope This standard establishes nominal voltage ratings and operating tolerances for 60-hertz electric power systems above 100 volts. It also makes recommendations to other standardizing groups with respect to voltage ratings for equipment used on power systems and for utilization devices connected to such systems. This standard includes preferred voltage ratings up to and including 1200 kV maximum system voltage, as defined in the standard.

Third parties must use certified equipment (both behind the meter and on the distribution grid) when attempting to interconnect new components to the grid. Certified equipment is equipment that has passed through rigorous certification testing procedures done by Nationally Recognized Testing Laboratories (NRTLs); UL is one such example. NRTLs create testing procedures for equipment that verify equipment functionality and safety to pre-set testing standards created by nationally recognized engineering groups such as IEEE.

This standard specifically applies to UPS with an electrical energy storage device in the DC link. It is used with IEC 60950-1, referred to in this standard as reference document (RD). It is applicable to UPS that are movable, stationary, fixed or for building-in, for use in low-voltage distribution systems and intended to be installed in any operator accessible area or in restricted access locations as applicable. It specifies requirements to ensure safety for the operator and layman who may come into contact with the equipment and, where specifically stated, for the service person.

The document applies to stand-alone rechargeable electric lighting appliances or kits that can be installed by a typical user without employing a technician. This technical specification presents a quality assurance framework that includes product specifications a framework for interpreting test results test methods and standardized specifications sheets templates for communicating test results.

The standard applies to a micro power plant which is the electric energy generation subsystem associated with a decentralized rural electrification system. It provides general requirements for the design, erection and operation of micro power plants and general requirements to ensure the safety of persons and property. The plants covered by this specification are low-voltage AC, three- or single-phase, with rated capacity less than or equal to 100 kVA.

The standard specifies the general requirements for the design and the implementation of micro grids used in decentralized rural electrification to ensure the safety of persons and property and their satisfactory operation according to the scheduled use.
