Despite this, the task of billing for every consumer is a time-consuming job for the distribution grid. Even though digital meters are replacing conventional electromechanical meters and provide many accurate readings, still the problem of deliberately making a false reading can exist (political reasons). Still, accuracy cannot be guaranteed as there can be errors in human reading. This can prove quite tedious as it involves various tasks like reading, then preparing the bill. The conventional method of electricity billing involves a person from the distribution unit reading the number of units of electricity consumed in the energy meter, conveying this information to the distribution unit, and then preparing the bill according to the units consumed for a fixed amount of time. Electronic Meters Need for Prepaid Energy Meter System: The digital signals are then processed using a DSP or a Microcontroller, which then displays the amount of energy consumed on an LCD or a LED display. ![]() Electronic meters consist of current and voltage sensors that sense the amount of current and voltage consumed and this analog signal is sampled and digitized using ADCs.
