Different types of load.

Load type	Load description	Transformer ratio
Balanced load	Three star-connected series load with  = 190  and  = 327 .	5 /3.3
Unbalanced load	series Load with  = 150  and  = 1.24  in phase-a, series load with  = 140  and  = 229  in phase-b, phase-c is open.
Nonlinear load	Uncontrollable three-phase bridge rectifier circuit, series circuits with  = 630  and  = 1.67  in DC side.
