Particular requirements for load-shedding equipment (LSE) (IEC 62962:2019)

Alkalmazási terület

The purpose of this document is to provide requirements for equipment to be used in energy efficiency systems. This document covers load-shedding equipment (LSE). Guidelines relating to safety for LSE as given in IEC Guide 110 have been followed. This document applies to load-shedding equipment for household and similar uses. The loadshedding function is used in energy management systems to optimize the overall use of electrical energy including production and storage. Load-shedding can be used for example for energy efficiency purposes as per IEC 60364-8-1:2019. This document applies to LSE for operation under normal conditions: – AC circuits with a rated frequency of 50 Hz, 60 Hz or both, with a rated voltage not exceeding 440 V (between phases), a rated current not exceeding 125 A and a rated short-circuit capacity not exceeding 25 000 A; or – DC circuits^1ˇ. LSEs are intended to control the energy supplied to one or more load, circuit or mesh when: – defined conditions of time and current are reached; – a command or information from an external system is received. An LSE is intended to serve as: – a single equipment having all the necessary means able to control the loads (e.g. the electrical energy management function is embedded in such an equipment); or – a unit integrated into a more complex equipment or an independent equipment being part of an electrical energy management system (EEMS); or – an assembly of independent equipment forming an LSE (e.g. an LSE with external current sensors); or – as a combination of the above points. LSE can have a wireless interface. LSE is part of the fixed installation. NOTE 1 This document covers load shedding equipment in the fixed installations including portable appliances connected thereto. LSE are intended for use in circuits with protection against electrical shock and over-current according to IEC 60364 (all parts). NOTE 2 For example, fault protection (indirect contact protection) can be covered as follows: – in TT systems, by an upstream RCBOs or RCCBs according to IEC 61008-1 and IEC 61009-1; – in a TN system, by an upstream over-current protective device. LSEs do not, by their nature, provide an isolation function nor the over-current protection. LSEs are normally installed by instructed persons (IEC 60050-195:1998, 195-04-02) or skilled persons (IEC 60050-195:1998, 195-04-01) and normally used by ordinary persons (IEC 60005-195:1998, 195-04-03). This document contains all requirements necessary to ensure compliance with the operational characteristics required by type tests for LSEs based on single equipment or based on an assembly of independent equipment. These requirements apply for standard conditions of temperature and environment as given in 5.1. They are applicable to LSEs with a degree of protection of IP 20 intended for use in an environment with pollution degree 2. For LSE having a degree of protection higher than IP 20 according to IEC 60529, for use in locations where arduous environmental conditions prevail (e.g. excessive humidity, heat or cold or deposition of dust) and in hazardous locations (e.g. where explosions are liable of occur), special construction can be required. If other functions are included in LSE, these functions are covered by the relevant standards. This document does not address communication aspects such as protocols, interoperability, data security and any other related aspects.
