This Part of GB/T 16927 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 as specified in GB/T 16927.1. For measurements during on-site tests see GB/T 16927.3. The limits on uncertainties of measurements stated in this Part apply to test levels stated in GB 311.1. The principles of this Part apply also to higher levels but the uncertainty may be greater. This Part includes: a) Defines the terms used; b) Describes methods to estimate the uncertainties of high-voltage measurements; c) States the requirements which the measuring systems shall meet; d) Describes the methods for approving a measuring system and checking its components; e) Describes the procedures by which the user shall show that a measuring system meets the requirements of this Part, including the limits set for the uncertainty of measurement.
