Scope

The verification system table for AC power measuring instruments is a procedure for transferring the unit value of AC electric power from the national AC power reference to various accuracy levels of AC power meters (single-phase, active power meters), AC standard power sources (single-phase), and AC/DC power conversion standard devices, etc.
It is applicable to the verification procedures of AC electric power measuring instruments with a range of AC current of 0.05 to 10 A, AC voltage of 7.5 to 600 V, power factor of 0.1 to 1.0, and frequency of 40 to 15,000 Hz.
Except for the verification procedures of single-phase reactive power and three-phase active and reactive power measuring instruments.
