When the protection and instrument share a set of current transformers, how to short-circuit the meter circuit when it is working?

The protection and instrument share a set of current transformers. When the meter is working, it must be short circuited on the terminal of the meter itself. Be careful not to open or short-circuit the protection. Currently, the secondary line of the current transformer is usually connected to the meter after being protected, so the meter is working. Short circuiting on the terminal of the meter itself does not affect the protection.
