Bus-Zone Protection

General Principles—Current Differential Protection—Voltage Differential—Frame Leakage Protection. Directional Comparison—Back-up—Supervision
  • A. R. van C. Warrington


There is some difference of opinion as to whether this should be called bus-zone protection or busbar protection. The former term is used by the author because the protection includes all the apparatus connected to the busbars.
