Inside the meter, you'll find components like voltage and current transformers, as well as sophisticated microprocessors. These components work together to accurately measure the electrical parameters of the three-phase system.

The voltage transformers step down the high voltage to a safer level that the meter can handle. The current transformers, on the other hand, measure the current flowing through the circuit. Both of these measurements are then fed into the meter's internal circuitry. The microprocessor is the brains of the operation. It takes the voltage and current measurements and uses them to calculate the power consumed. It does this by multiplying the voltage and current values together, taking into account the power factor, which represents the efficiency of the electrical system. The microprocessor also keeps track of the total energy consumed over time, accumulating the energy usage in kWh.

This data is then displayed on the meter's digital display, usually an LCD or LED screen. Most modern meters also have communication capabilities, allowing them to transmit this data to a remote server. This is how energy providers can remotely monitor your energy consumption and provide you with detailed usage reports. Some advanced meters even have features like time-of-use metering, which allows you to track your energy consumption during different times of the day and potentially take advantage of lower electricity rates during off-peak hours. The entire process, from sensing voltage and current to displaying the energy consumption, happens almost instantaneously, giving you a real-time view of your energy usage. It's pretty amazing when you think about it!
