Strategic Objectives

The electric utility industry is restructuring itself from regulated environment to operation under competitive wholesale. However Transmission & Distribution system remain regulated entities that connect deregulated generation to the end costumer. The pace of T&D investment has lagged behind the rate of load growth and generating capacity additions in many countries due to public, regulatory, environmental and financial obstacles to the construction of new T&D facilities. This results in saturation of many OHL reaching critical values of ampacity and sag. OTLM system helps operators with real time data on critical spans of OHL, supports real time rating of OHL and is essential for upgrading of saturated OHL.
