transformer is a static machine that can change the voltage from one level to another level without any change in power and frequency
ie when vtg reduces in secondary the current increases so as to keep the power in same value
V1I1 =V2I2
IN CASE OF POWER TRANSFORMERS THE SECONDARY CURRENT CAN BE EASILY FOUND OUT BY JUST DIVIDING THE kVA RATING BY .75

In a power conditoining unit (inverter) of a solar plant when we measure the d.c. current fed by different strings of solar plates to inverter, the current in the negative wire is less almost by 1 ampere to the current in its positive wire say current in positive wire 5 A , then current in negative wire of the same string is 4 A. Since the current entering should be equal to current leaving then why the current is noticably less in negative wire.
