WebThe most commonly used schemes for bus zone protection are: Backup protection Differential Overcurrent Protection Circulating current protection Voltage Overvoltage Protection Frame leakage protection. … WebFeb 6, 2012 · 2 Principle of busbar protection Kirchhoff’s current law states that the sum of current flowing into a point is zero. Applying this law to busbar protection, the current flowing toward the busbars must again flow away from the busbars so that the sum is zero. If the sum is not zero, the busbar protective relay declares a system fault and
