Anotácia textu normy IEC/TS 62749-ed.2.0-RLV :
IEC TS 62749:2020 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC TS 62749:2020 specifies the expected characteristics of electricity at the SUPPLY TERMINALS of public low, medium and high voltage, 50 Hz or 60 Hz, networks. NOTE 1 The boundaries between the various voltage levels can be different for different countries/regions. In the context of this TS, the following terms for system voltage are used: - low voltage (LV) refers to less than or equal to 1 kV; - medium voltage (MV) refers to between 1 kV and 35 kV; - high voltage (HV) refers to between 35 kV and 230 kV. While power quality is related to EMC in a number of ways this document is not an EMC publication. This second edition cancels and replaces the first edition published in 2015. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) minimum number of remaining data for weekly analysis, b) improvement of the compatibility between EN 50160 and IEC TS 62749, c) further explanation of the conception of daily sliding window, d) further explanation of the aggregation method used for events, e) further explanation of the relation between Power Quality and EMC, f) addition of a new definition of mains communicating system (MCS), g) addition of a new Annex G: Other phenomena, h) transfer of the main content of IEC TR 62510 to IEC TS 62749.
