POWER QUALITY MEASURING DEVICE USED IN DISTRIBUTION LINE FOR INTEGRATED VOLTAGE AND VAR CONTROL
First Claim
1. A power quality measuring and controlling device used in a distribution line comprising:
- a current-voltage sensor part converting a first voltage received through the distribution line into a second voltage, converting a first current into a second current, and signal-processing the converted second voltage and the converted second current and transmitting them by radio communications; and
a power quality measuring part receiving the second voltage and the second current from the current-voltage sensor part by radio communications, comparing measured values of the second voltage and the second current with reference measured values, and transmitting only measured data belonging to the reference measured values to the centralized system located in a remote place by radio communications.
