Answer / z_hosen

Good question..
If u want to connect two voltage sources at first u have to
follow some rules like
1. Phase sequence should be same
2. Frequency should be same and
3. Voltage should be same

if any two or more voltage sources which don't follow the
above conditions then current will be Inter circulated
between sources and if the voltage range is more then the
system will be damaged..
thanking u..

Answer / gunasekaran

1.phase sequence should be same
2.frequency should be same
3.voltage should be same
4.vector group should be same
5.percentage impedance should not more than 1:3
if voltage diff is there circulating current between two
voltage level so under normal condition itself tr getting
more core loss

voltage across the parallel circuits must be equal so its not possible to connect two sources in parallel to a load.
