Elspec Engineering Ltd (Elspec) is an Israel-based company active in the electrical industry sector. It is a provider of electrical power quality analyzers, real time power factor correction systems and energy saving solutions. The Company is engaged in the implementation of power quality analysis and power quality factor correction technologies as well as power quality solutions for the industrial, commercial and utility sectors worldwide. Power quality analysis technology optimizes power quality data analysis using patented data compression technology PQZip (Power Quality Zip), which enables continuous gap-less recording of all electrical parameters-related data for a significant time duration without the need of event thresholds of any kind. Elspec’s systems switch capacitor groups on and off using electronic switches; the connection and disconnection of capacitors occurs precisely at zero-current crossing so avoids transient effects.
