Description of BS EN IEC 60060-1:2025 2025IEC 60060-1:2025 is applicable to: - dielectric tests with direct voltage; - dielectric tests with alternating voltage; - dielectric tests with impulse voltage; - dielectric tests with combinations of the above. This document is applicable to tests on equipment having its highest voltage for equipment Um above 1,0 kV AC and 1,5 kV DC. This fourth edition cancels and replaces the third edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - The general layout and text have been updated and improved to make the standard easier to use, particularly the clauses for combined and composite test voltages. - The positive tolerance of the front time of lightning impulse voltage has been extended for Um > 800 kV to 100 % (= 2,4 µs). - For switching impulse voltage, a front time has been introduced, similar to lightning impulse voltage and with the new front time the standard switching impulse is defined as 170/2 500 µs. - The requirements for precipitations have been adjusted depending on Um. - A new Annex C, "Procedure for manual calculation from graphical waveforms" has been incorporated. - No examples of software have been given in Annex D, "Guidance for implementing software for evaluation of lightning impulse voltage parameters". - The annex relating to the "Background to the introduction of the test voltage factor for evaluation of impulses with overshoot" has been deleted. - A new informative Annex F, "New definition of the front time of switching impulse voltage" has been incorporated. NOTE 1 Alternative test procedures can be required to obtain reproducible and significant results. The choice of a suitable test procedure is considered by the relevant Technical Committee. NOTE 2 For voltages Um above 800 kV it is possible that some specified procedures, tolerances and uncertainties will not be achievable.
