Help all,

Here is my question:

2 single phase transformers work in parallel to supply a load with total load current of 750 amps at 0.8 lagging power factor. Using the test data of the transformers below, determine the impedances of the transformers and hence the secondary voltage and the output power and power factor of each transformer.

Test data;
Open circuit test: measured voltage: 11Kv/3300v for both
Short circuit test: (with HV side short circuited)
Transformer 1: Secondary input : 200v,400A,15kW
Transformer 2: Secondary input : 100v,400A,20kW

Help :blink:

2 and 1/2 years is a seriously cold thread. Chances are excellent it was his only post.

It was in fact his last post. RIP
