Con Edison, the Electric Power Research institute (EPRI), and the Empire State Electric Energy Research Corporation (ESEERCO) cosponsored a research program involving the installation and evaluation of a real-time monitoring and dynamic rating system on two feeders on the Con Edison underground transmission system. This article describes the preliminary results of the program. Con Edison's underground transmission system comprises more than 650 circuit miles of high-pressure pipe type cable operating at 69, 138, and 345 kV. The 345 kV cables are predominantly forced cooled. Forced cooling is achieved through the installation of cooling plants. The main components of a cooling plant are the pumps, air-to-fluid heat exchangers, refrigeration equipment, and hydraulic system. Various stages of the cooling system provide different levels of transmission capability (rating).
