In Railway,why we are used HT Line 25KV ?.why we are not used 11KV,33KV and others for This?
37 45455why dont we connect the two 12 V DC batteries in parallel, for an inverter (UPS)? is there any harm ?
6 9131will we have to design the UPS differently for both i.e. if we want to connect the two batteries in parallel and/or we want to connect the two batteries in series ?
4 6788in a 740 kw dc seperately excited motor field voltage is constant about 17.4 volts and armature voltage is500 volts dc. how it is possible to have two different voltages from single transformer of output voltage 500 volts? if any difficulty in question contact ajitsingh.kadian@gmail.com
1 4407IS there any mechanical connection between the field winding and armature winding of a dc generator?
