If a type H or L hydraulic recloser is rated for 14.4 KV, can it operate on a 2.4 KV line?

A type H or L hydraulic recloser rated for 14.4 kV can indeed operate on a 2.4 kV line. This compatibility arises because the operational voltage of the recloser exceeds the voltage of the line, meaning it can handle the lower voltage without challenge.

Reclosers are designed with specific ratings that signal their ability to safely break and restore service on lines at or below that voltage. Using a 14.4 kV rated recloser on a 2.4 kV line provides a safety margin and ensures the device can handle any potential over-voltages that may occur.

Moreover, while some equipment may have operational limitations at different voltage levels, in this case, the recloser's configuration and design make it suitable for use in this scenario without requiring modifications or additional components. Other potential answers suggest limitations or adjustments that are unnecessary given the robust nature of the recloser's rating compared to the line’s voltage.
