With a total of two patents to his name, Keckalo has developed innovative solutions aimed at enhancing the safety and reliability of power delivery systems.

Latest Patents

One of Keckalo's latest patents focuses on "Electric power distribution sectionalizing in high-risk areas using wireless fault sensors." This invention discloses systems and methods for ensuring safe electric power delivery protection within high-risk areas while maintaining electric power availability in non-faulted zones. The technology utilizes fault signals from wireless sensors at a recloser to block reclosing onto a faulted high-risk zone. Additionally, it allows for reclosing when the operation will not close onto a fault location within the high-risk zone. The system also incorporates selectively openable portions of the power system by sectionalizers, enabling a recloser to attempt a reclose operation affecting both the high-risk zone and the selectively openable portion when a fault is reported.

Another notable patent by Keckalo is titled "Methods and systems for sectionalizing a looped distribution line in a power distribution system." This invention involves a plurality of preprogrammed switches located in a looped distribution line downstream from a power source. These switches respond to short circuits and reconfigure the line to isolate the fault. Each switch is assigned a unique open time interval, allowing the system to identify which switch is opening in response to the short circuit and to protect the identified portion of the line.
