Abstract (en)

[origin: WO0048149A1] A modular power quality monitoring device, adaptable to an electrical anomaly detection circuit, such as a surge protection device (16), comprises an electrical connection to an AC power line, voltate surge detection circuitry (12), a neuron microprocessor (10), a DC power source (38) and a transmission circuit (42, 44, 46, 48 or 50). 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 (14) permits data stored by the modular device to be retrieved and/or viewed on a display (32). Various means of transmission can be employed, such as modulated power line transmission (42) or free topology - twisted pair (44), RS485 (46), fiber optics (48), RF carrier or computer modem connection (50).
