Description

The objective of this Standard is applicable to high-current testing and measurements on both high-voltage and low-voltage equipment.

Scope

This International Standard is applicable to high-current testing and measurements on both
high-voltage and low-voltage equipment. It deals with steady-state and short-time direct
current (as e.g. encountered in high-power d.c. testing), steady-state and short-time
alternating current (as e.g. encountered in high-power a.c. testing), and impulse-current. In
general, currents above 100 A are considered in this International Standard, although currents
less than this can occur in tests.
NOTE This standard also covers fault detection during, for example, lightning impulse testing.
This standard:
– defines the terms used;
– defines parameters and their tolerances;
– describes methods to estimate uncertainties of high-current measurements;
– states the requirements which a complete measuring system shall meet;
– describes the methods for approving a measuring system and checking its components;
– describes the procedure by which the user shall show that a measuring system meets the
requirements of this standard, including limits set for uncertainty of measurement.
