Title: Mary Ilyin: Innovator in Power Distribution Technology
Introduction
Mary Ilyin is a prominent inventor based in Walnut Creek, CA (US). She has made significant contributions to the field of power distribution technology, holding a total of 4 patents. Her work focuses on developing advanced fault sensor devices that enhance the reliability and efficiency of power distribution systems.
Latest Patents
One of her latest patents is a fault sensor suitable for use in heterogeneous power distribution systems. This innovative device executes a stored program to collect sufficient information to distinguish the source of fault current, whether it originates from a public utility portion of the power distribution network or from a distributed generator. The sensor reliably distinguishes short circuit current and magnetizing current based on differences in voltage-current signatures. Additionally, it periodically senses the condition of its battery and sends a digital data signal to a remote location when the battery power is low. After a sustained power outage, the sensor detects when power has been restored and communicates this information to a remote location. It also measures peak line voltage and peak line current, reporting these peak values to the remote location.
Another notable patent is a fault current sensor device with a radio transceiver. This device detects and distinguishes abnormal current events on both overhead and underground power transmission lines. It can identify whether a fault is a line-to-ground, line-to-line, or three-phase fault. The sensor determines if the overload has occurred on all three phases or only on one or two phases in an unbalanced situation. Furthermore, the device can be remotely reprogrammed to alter its trigger or threshold level and can be reset after a fault has occurred.
