#775 single-phase transformer ratings,

[nikhilgupta10]

The single-phase transformer ratings, especially using three individual connections in a WYE WYE configuration, is non-intuitive and not flexible enough to address many cases. For example:

object transformer_configuration {

...
power_rating 1500;
powerA_rating 500;
powerB_rating 500;
powerC_rating 500;
resistance 0.01;

}

Currently, the base kVA is assumed to be 1500 kVA. However, if this were coupled SINGLE_PHASE transformers, the base should actually be 500 kVA. Ideally, in fact, if declared as single phase, each phase should have its own rating and resistance and be calculated separately. For example:

object transformer_configuration {

...
//power_rating 1500;
connect_type SINGLE_PHASE;
powerA_rating 500;
powerB_rating 500;
powerC_rating 500;
resistanceA 0.01;
resistanceB 0.02;
resistanceC 0.03;

}
