My 6.0 kV distribution system have been designed the short circuit level at 25kA for 1 second. In case I purchase a MV motor, I always ask supplier to confirm stator terminal box shall be designed to withstand 25kA for 1 second.
Unless, the case motor is controlled via MV-VSD, most suppliers...
I'm purchasing MV motors which right now some suppliers propose to use winding temperature detection and protection as PTC, but some propose RTD PT100. Could you please anyone can clarify to me what is different of these elements? Which one have the advantages more than the other one?
Thank...
