Title: Ken Lau: Innovator in Power Distribution Technology
Introduction
Ken Lau is a prominent inventor based in San Francisco, California. He has made significant contributions to the field of power distribution technology, holding a total of four patents. His work focuses on enhancing the reliability and efficiency of power distribution systems.
Latest Patents
One of Ken Lau's 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 that distinguishes 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 effectively 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 power restoration and communicates this information to a remote location as well.
Another notable patent is the 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 the fault is a line-to-ground, line-to-line, or three-phase fault. The sensor also 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.
