Sensor accuracy is key: The measurement accuracy of zero-flux current transformers directly determines whether the system can accurately detect changes in ground currents at the milliampere level, which is the primary consideration when selecting a core monitoring system. The measurement range must be both wide and narrow: It must be capable of measuring normal ground currents at the milliampere level while also covering fault loop currents at the ampere level. A wide...
