A microprocessor-based digital feeder monitor with high-impedance & fault detection
- GE Protection and Control, Malvern, PA (United States)
The high impedance fault detection technology developed at Texas A&M University after more than a decade of research has been incorporated into a comprehensive monitoring device for overhead distribution feeders. This digital feeder monitor (DFM) uses a high waveform sampling rate for the ac current and voltage inputs in conjunction with a high-performance reduced instruction set (RISC) microprocessor to obtain the frequency response required for arcing fault detection and power quality measurements. Expert system techniques are employed to assure security while maintaining dependability. The DFM is intended to be applied at a distribution substation to monitor one feeder. The DFM is packaged in a non-drawout case which fits the panel cutout for a GE IAC overcurrent relay to facilitate retrofits at the majority of sites where electromechanical overcurrent relays already exist.
