Full Load Current Calculator for Transformer
The transformer full load current calculator can be used to determine the transformer’s full load current by entering the primary and secondary side voltage.
Selecting the transformer’s kVA rating and phase type (single-phase or three-phase) are basic requirements.
Formula
For Single Phase
IP= KVA Rating/VP
IS= KVA Rating/VS
For Three Phase
IP= KVA Rating/(√3 x VP)
IS= KVA Rating/(√3 x VS)
Where,
VP – Primary Voltage
VS – Secondary Voltage
IP – Primary Current
IS – Secondary Current
Turns ratio calculator for Transformer
The transformer voltage ratio is the proportion of primary to secondary voltage which is equal to the ratio of number of turns in primary & secondary side.
Turn Ratio = VP/VS = NP/NS
