Abstract

This paper describes the development of an Ethernet-enabled digitizer system with a digital signal processor suitable for isolated measurements in the field environment. An implementation using a commercial 24-bit analog-to-digital converter is described, giving a six-channel instrument capable of sampling with real-time data transfer and processing at up to 32 kS/s. Implementation of real-time power quality algorithms is described. Performance results are presented, which show accuracy within 10 μV/V.
