On November 23rd, 2011, Continental Control Systems released Option PT (Potential Transformer) for the WattNode® for LonWorks® product line. This provides enhanced support for potential transformers by adding a PT ratio configuration to the meter. Based on the configured PT ratio, the WattNode meter automatically scales the reported voltages, power, reactive power, energy, and demand values.

As part of the Option PT release, there is a detailed manual supplement available explaining the types of medium voltage circuits that can be monitored and showing wiring diagrams.
