Switchgear Diagnosis Continuous, comprehensive device monitoring:
{"Image DocumentName": "Switchgear Diagnosis Continuous, comprehensive device monitoring:", "Image ImageDescription": "Trip coil monitoring. Number of operations. Operating time. Charging time. For effective preventive maintenance! Especially enhanced switchgear diagnosis functions, derived from =SE= s experience as a manufacturer, to facilitate preventive maintenance of the breaking device: - trip circuit supervision: detects fault wiring between Sepam and switchgear trip unit. - number of operations. - operating time: measurement of the breaking device\u2019s opening and closing times in ms (typically between 50 and 100ms, please refer to manufacturer characteristics) if that time increases: downgrading of protection performances (increase in the duration of the fault), mechanical checking of the breaking device to be planned! - charging time: measurement of the breaking device operating mechanism charging time, in the case of operating mechanism charging by an electric motor, as soon as the circuit breaker is closed (in the range of 10 s, please refer to manufacturer characteristics, essential if recloser is used) if the time increases: sign of motor downgrading, charging time becomes incompatible with reclosing cycle, checking / replacement of the breaking device\u2019s electrical operating mechanism to be planned! - Cumulative breaking current: counted according to 5 levels of fault current. - SF6 pressure switch: all information of interest for switchgear maintenance!", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
