1 Scope

This procedure is applicable to electromechanical (induction system) AC energy meter with reference frequency of 50Hz or 60Hz (referred to as electric energy) The first test of the meter or the meter being tested does not apply to the on-site inspection of the meter. According to Appendix A of this regulation, the type evaluation test of electromechanical AC active energy meter is carried out.

2 Overview

The energy meter is used to measure AC active and reactive energy. Figure 1 is a simplified diagram of a single-phase electric energy meter measuring mechanism, the main group The components are described in the legend. Voltage and current cores stacked from silicon steel sheets, respectively wound with voltage coils and current lines ring. Phase voltage U of single-phase circuit Adding to the voltage coil, there is current I U flows through the coil and creates an aluminum turntable Alternating voltage working magnetic flux ΦU; load current flowing through current coil I , generating alternating current through the aluminum turntable Working magnetic flux ΦI. Voltage and current working magnetic flux with phase difference, passing through the turntable from different positions and inducing in the turntable Eddy current, each magnetic flux interacts with the eddy current to form a driving torque (average value) for driving the turntable to rotate.
