The Power Donut is a state of the art instrumentation platform designed for data acquisition and data logging applications on high voltage, overhead conductor systems. The Power Donut2 is completely self-contained. it is self-powered, it measures current ,voltage, MW, MVars, MWh ,conductor temperatures, stores data on board, and it transmits data on demand using a radio modem. The integration of a power line sensor network (PLSN) has been proposed to monitor such a utility asset’s status for maximizing existing power grid utilization with minimal risk of degradation and for extending the lifetime of said assets. The included sensors and wireless data communications system allow for the transmission of data pertinent to determining the ampacity of assets. Six USi Power Donut devices were used on 220 Kv transmission lines of a utility partner.The technology used inside the "donut" is a Motorola G24 cellular telephone module. The G24 unit is installed in the "Power Supply" pocket. The G24 product provides “2.5 G” service.
