  • Patent number: 10996244
    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.
    Type: Grant

  • Patent number: 10365302
    Abstract: A capacitor status monitor that attaches across the bushings on the exterior of a capacitor container (commonly referred to as a “can”). The capacitor status monitor, which draws operating power from the power line, detects the internal impedance of the capacitor can 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 an internal capacitor failure. The monitor may also include a power supply current transformer providing power to the monitor from the power line. Capacitor status monitors throughout the capacitor bank may communicate 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.

  • Patent number: 10241136
    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.
