Introduction  
This application note describes a single-phase power/energy meter with tamper  
logic. The design measures active power, voltage, and current in a single-phase  
distribution environment. It differs from ordinary single-phase meters in that it uses  
two current transducers to measure active power in both live and neutral wires.  
This enables the meter to detect, signal, and continue to measure reliably even  
when subject to external attempts of tampering.  
The heart of the meter is an AVR microcontroller. All measurements are carried out  
in the digital domain and measurement results are available in the form of  
frequency-modulated pulse outputs and as plain-text values, accessible over the  
USART interface. This enables the design to be used in cost-effective applications  
based on mechanical display counters. Alternatively, the design easily fits more  
computerized applications with features such as remote reading (AMR), demand  
recording, multiple tariffs, and other.  
A prototype built for 230V and 10A operation showed better than 1% accuracy over  
a dynamic range of 500:1. With careful PCB design and following the guidelines  
given at the end of this document the accuracy can be further increased. The meter  
is easily configured to fit any other voltage and current settings.
