Abstract
A device comprising a fault detector and communications module. The communications module can transmit and receive information and data via a commercial two-way wireless system, which may include two-way paging technology. The inventive device is capable of measuring imbalance currents in a remote capacitor bank, and if the imbalance current exceeds a set threshold the inventive device communicates this information, and/or other information, to an electric utility control center. The communications module is mounted using a standard utility meter socket, thereby allowing the communications module and an associated adaptive capacitor control to be stacked and mounted on the same meter socket to provide an integral unit. A two-way infrared communication port is also provided.
