HPL Electrical Watthour Meter

A single-phase power meter, as the name suggests, is a two-wire AC or altering current power circuit. It changes the supply voltage of the power simultaneously. Generally, it is called “residential voltage” since its usage is mostly found in homes. A single-phase energy meter uses electronic circuits and chips to measure electrical energy. A voltage divider or a voltage transformer is used to turn the voltage signal into a small signal that can be used for electronic measurement. DLMS stands for Device Language Message Specification. The objective of DLMS is to provide an interoperable environment for structured modeling and meter data exchange.
