| Abstract | |
The earth continuity conductor (ECC) is required in underground transmission systems that utilize single-point bonding or cross-bonding. Proper electrical design of these systems requires thoroughly analyzing the ECC's steady-state and transient behavior. This paper focuses on the influence of earth-return admittance, earth displacement current, and frequency-dependent soil parameters on the transient behavior and lightning response of the ECC. The results highlight significant differences in the ECC's performance when these factors are considered, particularly regarding overvoltages in the conductor and the energy capacity of the sheath voltage limiter (SVL), a device commonly used in single-point bonding configurations.
