Patent number: 10832859Abstract: A hardened inductive device and systems and methods for protecting the inductive device from impact is provided. The inductive device is hardened with protective coating and/or an armor steel housing. The hardened inductive device is protected from impact by an object such as a bullet and leakage of dielectric fluid is prevented. Acoustic and vibration sensors are provided to detect the presence and impact, respectively, of an object in relation to the inductive device housing. The measurements of the acoustic and vibration sensors are compared to thresholds for sending alarms to the network control center and initiating shut-down and other sequences to protect the active part. The acoustic sensor results are utilized to determine the location of origin of the projectile.Type: GrantFiled: August 19, 2019Date of Patent: November 10, 2020Assignee: ABB Schweiz AGInventors: George K.
