LCB II high-speed current differential relay system

The LCB II provides high speed protection for long and short lines

The LCB II provides high speed protection for long and short lines. It is particularly suitable for lines too short to be protected by impedance measuring systems, such as the run from generator to switchyard. The channel flexibility built into the LCB allows application on lines up to 400 kilometers. The LCB is suitable for any system voltage from subtransmission through UHV. The LCB is available loose and unmounted, or completely mounted and wired in a panel or cabinet.
