Distributed Busbar Protection CSC-150
CSC-150 combined with CSC-211 forms a distributed busbar differential protection system suitable for conventional and digital substations.It provides selective, reliable, high-speed protection with programmable logic for busbar faults and breaker failure in substations. It supports a wide range of busbar configurations, including single busbar, single busbar with section, double busbar, double busbar with transfer bus, one-and-a-half breaker, double busbar with one or two breakers/sectionalizers, configurations with bypass.
Easy expansion capability, up to 40 bays
Comprehensive functionality including phase segregated low-impedance current differential protection, breaker failure protection, overcurrent protection, earth overcurrent protection and dead zone protection, etc.
Voltage blocking is an option for the current differential protection and breaker failure protection, which will improve reliability of current differential protection and breaker failure protection
With CT circuit supervision function, once CT circuit failure is detected, the user can choose CT failure alarm or discrimination zone differential protection blocking
With the disconnector position status monitor and memory function, the device will delay the alarm and operate according to the original normal state
Bay unit CSC-211 works in the distributed busbar protection system, also as feeder backup protection IED
Powerful scalable hardware capability, for present and future application
Robust hardware with excellent EMC performance and IP54 protection under -40℃ to +70℃ operating temperature
