equipment, e.g., turbines, generators, transformers, reactors,
circuit breakers, battery banks, underground/underwater
cables, and overhead transmission lines, as depicted in Figure 4. Sensors, e.g., dissolved gas analyzers, temperature,
pressure, and vibration monitors, PD and acoustic sensing,
IR cameras, dynamic line rating equipment, and icing and

galloping detection systems have been installed at the company's assets fleet wide. By networking these sensors to the
iSOC, it is expected that more than 130,000 data points will
be transmitted to this new monitoring and diagnostic hub.
The iSOC currently collects more than 45,000 data points
spanning the New York State grid and feeds the data into
