What type of lightning arrestor would typically be installed in a 230-kilovolt switching yard?

In a 230-kilovolt switching yard, the installation of a station arrestor is most appropriate due to its capability to withstand and safely divert high voltage surges caused by lightning strikes or switching operations. Station arrestors are specifically designed for use in substations and large switching stations, where they protect equipment by ensuring that excess voltage does not damage transformers, circuit breakers, and other critical infrastructure.

These arrestors are strategically placed to provide adequate protection across the entire switching yard, effectively routing harmful electrical surges to the ground. Given the high voltages involved in a 230-kV system, the robustness and design of station arrestors make them the ideal choice compared to other types of lightning arrestors, which may not be suitable for such high levels of voltage and could potentially lead to equipment failure or safety hazards.
