Answer Posted / me
we have a 3 phase transformer rated as:
45 KVA 60 Hz
Primary volt: 480v
Secondary volt; 120 v single phase, 220 v (L-L)
How can I calculate the Secondary maximum current (max.
load)
I have measured the Secondary current with clamp ammeter as
follow;
X: 72.6 A; Y: 64.6A; Z: 68.1A
Regards
