Patent number: 11360121Abstract: A sensor for measuring current flow includes a power generation circuit, a current measurement circuit and a microcontroller. The power generation circuit includes a current transformer that harvests energy from a load applied to the conductor and uses the harvested energy to power the current measurement circuit and microcontroller. The current measurement circuit includes a Hall effect sensor that outputs a voltage signal in response to detecting a magnetic flux generated by the flow of current through the conductor. The microcontroller calculates a current measurement based on the voltage signal received from the current measurement system. The Hall effect sensor is able to generate the voltage signal used to measure current flow at the same time that the current transformer harvests energy from the current flowing through the conductor. A fault detection system is able to alert a user to problems with the current transformer and/or the Hall effect sensor.Type: GrantFiled: April 13, 2020Date of Patent: June 14, 2022Assignee: JOHNSON CONTROLS TYCO IP HOLDINGS LLPInventors: Ashok Sridharan, Hariprasath Muthumanickam, Sushilkumar Madhukar Pagar, Atul Dinesh Shukla, Hariharasudhan Venugopal, Ankur Thareja
