Centralized Busbar Protection CSC-150
CSC-150 is a centralized busbar differential protection IED suitable for both 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.
Up to 26 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
Mixable Binary inputs & output relays / GOOSE inputs or outputs
Robust hardware with excellent EMC performance and IP54 protection under -40℃ to +70℃ operating temperature
