Transformer Impedance Question
Transformer Impedance Question
(OP)
I used to work with an EE who claimed that the impedance losses from the transformer are overlooked and shouldn't be. According to him, at full load, the voltage drop is about 2/3 of the impedance percentage.
Because of this, he would always specify very low impedance transformers. I argued that the trade-off in Short Circuit current isn't worth the voltage stability.
What do you all think?

In our "discussions" about this with my EE friend (and don't get me wrong - I have a lot of respect for this guy) I argued that the tradeoff in safety and cost didn't seem worth it when you could adjust using the taps. His argument is that if you have a variable load, the taps will cause you to drift too high during low load cycles.
I get the argument - I guess I just don't agree. If your load is that sensitive to voltage fluctuations, you can put it behind a UPS or some other power conditioner, right?
