20130049728, Feb 28, 2013

Filed:

Aug 29, 2012

Appl. No.:

13/597832

Inventors:

Karl Eric Fender - Greenwood SC, US
Clay L. Fellers - Little Mountain SC, US

Assignee:

COOPER TECHNOLOGIES COMPANY - Houston TX

International Classification:

G05F 3/02

US Classification:

323311

Abstract:

A boost device is coupled to a compensation device that is configured to be connected to a power system. The boost device includes multiple portions, each of the multiple portions including at least one electrical element, and a solid-state switching device electrically connected to the at least one electrical element. The solid-state switching device is connected in parallel with the at least one electrical element such that closing the solid-state switching substantially prevents current flow to the at least one electrical element.

Abstract:

A high voltage capacitor includes multiple capacitor packs housed in a canister. A capacitor pack status monitor includes a current sensor measuring an electric current through an associated capacitor pack and a radio transmitting a first signal representative of the electric current through a selected capacitor pack. The monitor also includes a voltage sensor measuring an electric voltage across the associated capacitor pack and a radio transmitting a second signal representative of the electric voltage across the selected capacitor pack. Electronics compute an impedance associated with each capacitor pack. Each current sensor may include a current transformer positioned around a main power line energizing a respective capacitor pack. Each voltage sensor may include a relatively large high voltage discharge resistor connected across the respective capacitor pack, and a relatively small voltage measurement resistor connected in series with the relatively large high voltage discharge resistor across the respective capacitor pack.

Abstract:

A high voltage capacitor current monitor that attaches to a bushing on the exterior of a capacitor container (commonly referred to as a “can”). The capacitor current monitor, which draws operating power from the power line, detects the current flowing through the high voltage capacitor and can be used as part of a capacitor status monitor to detect internal failures down to the level of a single capacitor pack. The monitor may include a radio transmitter and/or a visual status indicator, such as an electronic flag, indicating the detection of a fault or capacitor failure. The current monitor may also include a power supply current transformer providing power to the monitor from the power line. Capacitor current measurements may be communicated with a remote transmission unit (RTU), which communicates with a central control station that schedules capacitor maintenance based on the data received from the status monitors.

International Classification:

G01R 31/02
H02J 3/18

Abstract:

A first electrical response of a capacitor bank is accessed, the capacitor bank including a plurality of capacitor units arranged in a fixed spatial relationship with each other, each capacitor unit having a nominal impedance; a test electrical signal is provided to the capacitor bank; a second electrical response of the capacitor bank is measured after providing the test electrical signal to the capacitor bank; the first electrical response of the capacitor bank and the second response of the capacitor bank are compared; and whether an impedance of one or more capacitor units in the capacitor bank has changed relative to the nominal impedance is determined based on the comparison.
