CSC-326-EB-D is a highly selective, reliable, and high-speed transformer differential protection IED designed for medium-voltage two-winding and three-winding power transformers.It provides robust differential protection as the primary function, backed by a comprehensive suite of integrated protection features. With fully flexible and programmable logic, it seamlessly adapts to all winding connection types and transformer configurations.
Integrated protection function and bay control unit function
Meeting demands for three-phase tripping in transmission and distribution grid
Circuit breaker position status monitoring
Equipped with module self-check function
Provide complete report records, including operation report, alarm report and tripping report. Up to 2000 reports can be stored, and the reports can be saved, even there is a power outage
It at most provides three electric/optical Ethernet ports, and communicates with substation automation system by choosing protocol IEC 61850 or IEC 60870-5-103 (TCP103)
RS485 is provided to communicate with substation automatic system by protocol IEC 60870-5-103
Support PRP protocol based on IEC 62439-3, the device can be set to PRP mode, and the dual network ports adopt redundant mode to send and receive information in parallel
Simple network time protocol (SNTP), pulse, IRIG-B or 1588 synchronizing modes can be selected to time synchronization;
Friendly MMI
Can be centrally installed in the switchgear panel or be installed on the switchgear indoors or outdoors
