Povon home energy monitor part 1, 20 channel system

P5120542-1024x769

Coyt Barringer documented his home energy monitor project called POVON. This first part of a series will detail the 20 Channel sub-metering hardware:

Our initial goal was to monitor power consumption in different parts of the house, and we quickly realized every household circuit would need to be monitored. After some research, small clip on current transformers, or CT’s, looked to be the best sensor for our application. Using CT’s, current draw and thus power on each circuit can be measured. The CT’s would be installed on the wires immediately leaving the circuit breakers in the standard household breaker box. CT’s work great for this because they’re completely isolated and nothing needs to be disconnected to install them.
