WebThe Agile P747 provides complete protection for voltage levels of busbar configurations up to extra high voltage (EHV) with a centralized 3-box architecture. The Agile P747 can accommodate up to 4 zones plus verification zone and protect up to 18 terminals. MICOM AGILE P746 RELAY In most substations, two nos.class PS cores per feeder are used for busbar protection – one for the main zone and the other for the check zone. Whenever two cores are available, a protection scheme that utilizes both the cores must be employed for busbar protection. See more In the olden days, the clearance of busbar faults was done by time-delayed distance relays or overcurrent relays, resulting in an extension of fault for a longer duration of time.

WebThe busbar protection discriminating zones will then trip the part of the substation that is faulty. The releasing when the check zone detects a fault is normally done by sending out positive DC-voltage to the discriminating zones. Another way to do the releasing is to connect the negative DC voltage to all trip relays WebProvide flexible, subcycle, low-impedance bus differential protection for various busbar topologies and sizes with the SEL-487B.
