Open circuit test is when the secondary is open, the voltage ratio of secondary ot primary represents at time becomes standard an usually represents the turns ratio between secondary and primary Short circuit test is the same but with current, generally don't us short circuit but normal operating conditions. Basic way to look at is power in equals power out, not exactly due to losses, which gives the relations of Vp Ip = Vs Is therefore Vs/Vp = Ip/Is
