Description

Three-Phase Analog Electric Meter:

Key Points

1. Components:
   • Multiple Dials: Typically 3 or 4 rotating dials for each phase (R, Y, B, and sometimes a total register).
   • Induction Disks: A metal disk for each phase, rotating based on current flow, and influencing the dials.
   • Magnetic Field Coils: Create a magnetic field that drives the induction disks.
   • Register: Displays the total energy consumption (in kWh) accumulated from all phases.
2. Operation:
   • Each phase (R, Y, B) has an induction disk that rotates based on the load (current flow).
   • As current flows through the meter, the magnetic field rotates the disks, which in turn moves the dials to indicate the consumption.
   • The readings from each phase are added together to show the total consumption.
