SR EN IEC 60060-2:2025

IEC 60060-2:2025 is applicable to complete measuring systems and to their components, used for the measurement of high voltages during laboratory and factory tests with direct voltage, alternating voltage and lightning and switching impulse voltages and combined and composite voltages as specified in IEC 60060-1. For measurements during on-site tests, see IEC 60060-3. The limits on uncertainties of measurements stated in this document apply to test levels stated in IEC 60071-1. The principles of this document apply also to higher levels but the uncertainty can be greater. This document: • defines the terms used; • describes methods to estimate the uncertainties of high-voltage measurements; • states the requirements that apply to measuring systems; • describes the methods for approving a measuring system and checking its components; • describes the procedures by which the user demonstrates that a measuring system meets the requirements of this document, including the limits set for the uncertainty of measurement.
