Bus protection alarm setting for CT disconnection is too low
The CT Trouble function in the B30 and B90 relays detects this condition by using a low-set differential element, typically set around 10% of the least heavily loaded circuit connected to the bus, that asserts after a settable time delay. tection scheme requires several key considerations. For substations with terminals capable. The high fault magnitudes increase the possibility of CT saturation during external faults close to the busbar, and CT saturation increases the possibility of an incorrect operation of the busbar protection. Many. Bus differential protection calculation plays a critical role in securing power systems. Protection engineers need precise methods to detect and isolate these faults without affecting surrounding equipment. Or we need a separate protection CT core that will be just for busbar relay? Is there any rule about this? BR Authentication Failed.
