determine a resistance of the fuse element in reference to the injected current or voltage while the electrical current is flowing through the fuse element from the energized line side circuit and while the voltage or current source injects the current or the voltage across the fuse element; and
calculate the electrical current flowing through the fuse element from the energized line side circuit based on the received first voltage and the determined resistance of the fuse element.

SIMILARITY DETECTION OF ABNORMAL WAVEFORMS USING PMU MEASUREMENT

Hitachi, Ltd., Tokyo (JP...

1. A system configured to manage one or more phasor measurement units (PMUs), the system comprising:a memory configured to store measurement data from the one or more PMUs, the measurement data comprising first measurement data including at least one of frequency data and voltage data, and second measurement data; and
a processor configured to:
for an instance of the first measurement data being outside a threshold:
identify a corresponding PMU from the one or more PMUs associated with the instance; and
capture, based on the instance, a first window of the first measurement data and the second measurement data of the corresponding PMU;
process incoming data from the one or more PMUs;
for a second window of the incoming data corresponding to the first window,
retrieve the first measurement data and the second measurement data corresponding with the instance; and
conduct a comparison between the first window of the first measurement data and the second measurement data, and the second window of the incoming data.
