Comprehensive and scalable bus and breaker fail protection for LV, HV and EHV busbars.The B90, a member of the UR Family, features integrated protection and breaker failure for re-configurable LV, HV, EHV multi-section busbars up to 24 feeders. Use one or more B90s together to build a sophisticated protection system that can be engineered to meet the specific application requirements. The B90 performs fast and secure low impedance bus protection with sub-cycle tripping time averaging 0.75 cycles. More InfoBuy Now
B30 Bus Differential System
Cost effective bus protection and metering for up to six feeders.The B30, a member of the UR Family, is a digital device that features integrated protection for HV and EHV busbars, providing cost effective, feature focused busbar protection. Use the B30 to protect busbars with up to 6 feeders, 1 zone. Consider the B30 as a cost effective alternative to high impedance schemes, ideal for breaker-and-a-half bus schemes, with integrated feeder backup protection and metering. More InfoBuy Now
MIB High Impedance Bus Differential System
Three-phase high impedance differential protection for substation busbars.The MIB, a member of the MII Family of protection relays, is a high impedance busbar protection relay, designed to provide busbar differential protection for single or split busbar arrangements. The MIB can also be used to provide zero sequence differential (restricted ground fault) protection for reactors, generators, and large motors. More InfoBuy Now
HID High Impedance Differential Module
Auxiliary resistors and varistors for high impedance differential schemes.The HID module provides resistors together with voltage limiters (MOVs) normally used in conjunction with a high-speed overcurrent relay to achieve high impedance differential protection. Use the HID in applications that include high impedance differential protection for busbars and electrical machines, such as transformers, generators or motors, as well as restricted earth fault protection.
