MUMBAI, India, July 31 -- Intellectual Property India has published a patent application (202617067915 A) filed by Eaton Intelligent Power Limited on May 30, 2026, for Health Monitoring Of Electromagnetic Relay.
Inventors include Harlapur, Vishakha Vilas; Bartonek, Michael; and Jagadale, Ramesh Raosaheb.
The application for the patent was published on July 24, 2026, under issue no. 30/2026.
Abstract: Described herein is an electromagnetic relay and a system comprising said relay. The relay comprises an electromagnetic drive unit, comprising: a rotatable armature having a first magnetic contact region; a yoke having a second magnetic contact region, the first magnetic contact region being in physical contact with the second magnetic contact region in a first state of the relay; and at least one coil wound at least in part around a portion of the yoke. The relay further comprises a fixed electrical conductor and a rotatable electrical conductor coupled to the rotatable armature, the rotatable electrical conductor configured to be in electrical contact with the fixed electrical conductor in the first state of the relay. The electromagnetic drive unit is configured to apply a current through the at least one coil to cause the armature to rotate to a second state of the relay, wherein in the second state of the relay the rotatable electrical conductor is not in electrical contact with the fixed electrical conductor and the first magnetic contact region is not in physical contact with the second magnetic contact region. The relay further comprises means for measuring a voltage across the at least one coil. Means for determining, based on one or more characteristics of the measured voltage, a status of the electromagnetic relay are also provided as part of the relay or system.
