Title: A Prototype System for Non-Intrusive Monitoring of Electric Loads
Author(s): Orion Zavalani               

Abstract: This paper discusses some aspects related to using and developing an NILM system. It reviews modern techniques and illustrates a prototype with reliable results from field testing. The NILM system prototype presented in this paper is dedicated for load monitoring, events detecting, and appliance monitoring of small consumers. NILM technology provides an ideal platform for load monitoring and fault diagnostics with easy and low cost installation, without disturbing consumers or users. NILM technology can be used successfully in different military facilities, equipments or devices. Potential applications are illustrated and discussed.

Keywords: non-intrusive, load, monitoring, diagnostic, event detection, appliance, signature, prototype system.
