2.1 Overview
Surge filter terminals for the field supply and K-bus supply
The surge filter terminals include overvoltage filters for the K-bus (Bus Coupler) and/or field supply (power
contacts).
The filters protect the components from line-bound surge voltages that can occur due to high-energy
disturbance variables such as switching surges at inductive consumers or lightning strikes at the supply
lines. The surge filter terminals can be used to protect the Bus Terminal station from damage in particularly
hostile environments. The ship classification organizations stipulate the use of surge filters in shipbuilding
applications and in the onshore / offshore sector.
