Пристрій для контролю ресурсу групи комутаційних апаратів

Abstract

The proposed device for checking the service life of a group of switching units contains current transducers, switching detectors, service-time meters inserted in the corresponding phase circuits of the switching units, an analog-to-digital converter for the current transducers, a unit for correcting the service life with consideration for irregular operation of the switching unit, and a timing unit.
