1. Single-phase energy meter: Inductive energy meter basic structure is similar, mainly by driving the original (including current components and
Voltage components), rotating elements, bearings, brake elements (made of permanent magnets), calculation mechanisms (counters), adjustment devices (which include full load, light load, phase, creep adjustment), auxiliary components.
2. Three-phase energy meter structure for two or three groups of single-phase energy meter components of the combination.
3. The three-phase all-electric meter internal structure consists of all the electronic components: including current and voltage sensors, analog-to-digital converters, calendar clock, dedicated microprocessors, the general display of the contents are:
① the current date -
② total active power - tip, peak, flat, valley.
③ total reactive power - with emotional, capacitive.
④ the maximum demand for time points.
⑤ accumulated pressure time (power).
