Application note
Single-phase energy meter with tamper detection
based on ST7FLITE2x

Introduction
This application note describes the design for a single-phase power / energy meter with
tamper detection. The design measures active power, voltage, current, power factor and line
frequency in a single-phase distribution environment and displays active energy, voltage,
current, power factor, line frequency, current date and time. It differs from ordinary single-
phase meters in that it uses two curre
