DEVICE FOR DETERMINATION OF ELECTRIC DISCONTINUITY BETWEEN ELECTRIC CONTACT AND ELECTRIC CONDUCTOR INSTALLED WITHIN DETERMINATION CIRCUIT Russian patent published in 2013 - IPC G01R31/02

Abstract RU 2482505 C2

FIELD: electrical engineering.

SUBSTANCE: external determination circuit includes a resonant circuit the resistance whereof varies when a contact is opened. The frequency of the determination circuit varies between two values corresponding to the two contact states (open and closed) and is used by the electronic processing module (8) issuing a malfunction signal when a contact is opened.

EFFECT: expansion of functional capabilities.
