Static or Electronic Energy Meters
Electronic energy meters are replacing traditional electromechanical meters in several residential, commercial and industrial applications since of the versatility and low-cost afforded through electronic meter designs. The measurement circuits are electronic along with LED (Light Emitting Diode)/LCD (Liquid Crystal Display) display and their accuracy is classically class 0.2, 0.5, 1.0. They cater to multiple tariffs for all segments CT-VT (Current Transformer - Voltage Transformer) operated, CT operated, 1-phase or 3-phase Direct connected segment. These meters record active and measure, apparent and reactive demand or energy. The static energy meters are microprocessor based and have non-volatile memory to record and store data. The electronic meter within its basic form has a power supply, a metering engine and a processing or communication engine, that is, a microcontroller, other add-on modules like as LCD display, Real Time Clock (RTC), communication ports/modules and etc.
These meters are extremely hard to tamper along with and if somebody does attempt to tamper them, they will send alarm signals and record the information. The programmability of microprocessor has become a meaningful tool for incorporating variant characteristics like Tamper data, Time-of day metering, Import- Export, load pattern analysis and etc. They could be made SCADA (Supervisory Control and Data Acquisition) systems compatible. They could have communication ports to support AMR/RMR on several communication platforms as well as for downloading of data.
