Tools to improve power quality, - such as Power Factor Correction (PFC) systems, feeder transformers, gear switches, etc. - can be effectively designed using data collected and analyzed by Spot™.

Power quality data, - such as apparent, active, reactive power and energy; voltage; current; THD; etc -. are collected from smart meters, used mostly by large consumers. Those meters transfer data to WEG-7 data logger devices which include point to point (P2P) GSM/GPRS modems, enabling data transfer to the central Metering Data Management (MDM) system.
