disatance shutdown of a 2400Volt 200HP motor
(OP)
Does anyone have any suggestion on what equipment I can use to shutdown a 2400 volt motor that is 3000' away from a control house or have any idea on how this should be done?
Thanks
Thanks

You could place the switch locally or maybe use a very BIG solenoid at remote location powered by 120 VAC??

Try giving more details. If you don't know the details needed you probably shouldn't be attempting this alone.

But just to throw in another plug, that's what a local EE would be doing for you...

You'd need a big plug. A sturdily mounted wall socket. 8<) And wouldn't ever do it twice.
(On a more serious note: At 3000 ft, when does it become impracticable to run a longer a and longer low voltage service/control lead wire (and all the grounding issues and conduit supports and road crossings, etc, etc. that it needs) and go to a wireless control system? Or are radio controls always ruled out because of their reliability and interference issues?

Solid-state relays with a DC input are your friend - they draw little current from the line (minimal volt-drop) and are very tolerant of input voltage (typically 3 - 32V DC). I used this method to control a remote pump station on a neighbouring site, with a loop length of well over a mile on 2.5mm² cable. It solved a long history of intermittent control problems, with various attempts including paralleled cores, and high drive-end voltages having been tried previously.
