Problem Addressed

Reducing utility customer power consumption could lead to improvements in greenhouse gas emissions. With the help of power monitoring information, a smart grid can allow customers to capitalize on energy savings. Centralized power monitoring systems identify and monitor loads according to their current signatures. These systems employ closed or clamp core sensors to provide current sense signals, which are impractical in many retrofit applications. Firstly, skilled labor is required to separate line and neutral in order to deploy a wrap-around sensor, and secondly, in some industrial environments electrical service interruption may be unacceptable or prohibitively expensive. Non-contact power monitoring addresses both of these problems, but current solutions require replacement of the existing circuit breaker. As a result, there is a significant increase in cost on the consumer end.
