A modular power quality monitoring device, adaptable to an electrical anomaly detection circuit, such as a surge protection device, comprises an electrical connection to an AC power line, voltage surge detection circuitry, a neuron microprocessor, a DC power source and a transmission circuit. The modular device is capable of detecting a plurality of electrical anomalies, such as voltage levels, current draw, power surges, phase outages, phase shifting, power factor, harmonic distortion and panel load. A plurality of the modular devices can be employed about a facility to create a power quality control network. A user interface permits data stored by the modular device to be retrieved and viewed on the display. Various ways of transmission can be employed, such as modulated power line transmission or free topology-twisted pair, RS485, fiber optics, RF carrier or computer modem connection.
