All the phase voltages and currents are stepped down to the acceptable levels of energy
meter chip. It process the acquired signal and performs the signal processing such as
digitizing, filtering and averaging to extract active power, RMS values of current and
voltages required computes the consumption of the energy. The measured values are
stored as bit streams in the registers. These registers are accessed by serial interface using
the microcontroller. Micro Controller accesses the data from the chip and displays the
various electrical parameters and energy consumption for the EB Source with on hours on
the LCD screen.
