摘要
The current flux determining device has a magnetic flux conductor linked with a current loop and carrying the collected flux, especially for application in a fault current circuit breaker, which responds to both AC and DC faults and to changes in normal operation due to component failure in the instrument itself. The current loop is the constituent part of a detector circuit which determines its induction and means to monitor the characteristics of the detector circuit are also provided. The detector circuit may be an oscillatory circuit or the frequency determining part of a relaxation oscillator.
