I was recently asked to do a motor starting study by the local utility for a 250hp vertical turbine pump. They are worried that the line voltage may sag more than 2% on startup, and if so, they may place restriction on time of day that it can be run. Now, I know enough in ETAP to be dangerous...
Hello,
I just created a star coordination in ETAP, but it seems that all displayed values are being transformed through my transformer turns ratio.
The simulation is very simple: 25kv overhead electrical service into a 25kv/600v 1000kVA transformer with primary fusing. On the secondary there...
Never done this before as I am an electronics guy. Need to size an Aluminum conductor to feed a 3ph induction motor that is 550 meters (1800 feet) away. Motor is 600v and faceplate current says 85 amps. Power factor 80%. Allowed 5% voltage drop on the line. What size of conductor do I...
