Electrical safety in low voltage distribution systems up to 1 000 V AC and 1 500 V DC - Equipment for testing, measuring or monitoring of protective measures - Part 5: Resistance to earth

IEC 61557-5:2019 is available as IEC 61557-5:2019 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 61557-5:2019 specifies the requirements applicable to measuring equipment for measuring the resistance to earth using an AC voltage. IEC 61557-5:2019 cancels and replaces the second edition published in 2007. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) definitions and symbols in Clause 3 modified; b) subclauses in Clause 4 restructured and aligned with other parts of the series; c) limits for reduced voltages 25 V RMS or 35 V peak removed from 4.5; d) requirements for clamps added; e) marking for rated voltages to earth and measurement category added to Clause 5; f) warning about absence of hazardous voltage added in Clause 5; g) the term "percentage operating uncertainty" replaced by "operating uncertainty" in Clause 6; h) equation for uncertainty corrected in Table 1; i) new Annex A on test measurements with loop clamps added.
