His work focuses on enhancing the reliability and efficiency of electrical systems, particularly in detecting faults and managing power distribution.

Latest Patents

One of Mayeda'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 or a distributed generator. The sensor can reliably differentiate between short circuit current and magnetizing current based on variations in voltage-current signatures. Additionally, it periodically monitors the condition of its battery and sends a digital signal to a remote location when the battery power is low. After a power outage, the sensor detects when power is restored and communicates this information as well.

Another notable patent is the fault current sensor device with a radio transceiver. This device is designed to detect and distinguish abnormal current events on both overhead and underground power transmission lines. It can identify various types of faults, including line-to-ground, line-to-line, and three-phase faults. The sensor is capable of determining whether an overload has occurred on all three phases or just one or two phases in an unbalanced situation. Furthermore, it can be remotely reprogrammed to adjust its trigger or threshold levels and can be reset after a fault has occurred.
