Classification: CPC G  H  Y | IPC G

Claim 16:
17. A recloser for controlling power flow on each power line of a three phase system in a medium voltage distribution network, the recloser comprising:
a separate current sensor for measuring primary current on each line;
a separate voltage sensor for measuring primary voltage on each line at one side of the recloser;
a separate voltage sensor for measuring primary voltage on each line at another side of the recloser;
an analog-to-digital converter (ADC) for converting measurement signals from the current sensors and the voltage sensors to digital signals;
a phasor measurement unit (PMU) responsive to the primary current and voltage measurement digital signals and calibration data, the PMU calculating magnitude and phase angle synchrophasor data; and
a communications module for transmitting the PMU data.
