Assignee:

Cooper Technologies Company - Houston TX

International Classification:

G01R 31/08

US Classification:

324522, 324 86, 361 76, 323300

Abstract:

A control system for an electrical power system includes an electrical corrective device, a voltage measuring device coupled to each phase of the electric power system, a current measuring device connected between each phase of the electric power system and the electrical corrective device, and a protective device connected to outputs of the voltage measuring device and the current measuring device. The protective device includes a controller configured to detect an imbalance using the measured voltages and currents output from the voltage measuring device and the current measuring device without using or independently of other recent voltage or current measurements for other points in the electrical corrective device and independently of a neutral-ground measurement at the electrical corrective device.

17/234199

Inventors:

- Azusa CA, US
John McCall - Rancho Cucamonga CA, US

International Classification:

G01R 31/50
G01R 19/00

Abstract:

A current monitor for a transmission line having powered active components is provided. A current monitor includes: a housing configured to be coupled to a transmission line, an inductive current sensor in the housing configured to measure a value of the current on the transmission line to generate a sensor signal, a power source, and a sensor signal conversion circuit in the housing configured to receive power from the power source and to generate a current output signal based on the sensor signal, the current output signal having a natively useful form.

International Classification:

G01K 13/00
G01S 17/08
G01R 19/00

Abstract:

A system and method for determining a reliability line rating for a transmission line is disclosed. In response to a line clearance measurement and a line temperature measurement received from a transmission line monitor coupled to a transmission line, the system generates a temperature-clearance model for the transmission line based on the received line clearance measurement and line temperature measurement. The system generates a plurality of past dynamic line ratings and determines a scaling factor based on the plurality of past dynamic line ratings. The system then generates a dynamic line rating for an interval of time in the future and scales the dynamic line rating in response to the scaling factor to obtain a reliability line rating for the interval.
