Can anyone help me with the accurate calculation of ratio and phase errors in measuring current transformers?
I would like to get a spreadsheet or something similar together for the design of toroidal bushing transformers and so far have not come up with any equations or methods that agree with...

Hi All
Can anyone help me with the calculations involved in a transformer short circuit impedance test. I have the following data:
Transformer rated voltage =230v
Transformer rated power = 960VA
Secondary short circuited during test
ambient temperature during test = 22 deg.C
Measured...
Dear Experts
Can anyone tell me how I can calculate the rms magnetizing current of a transformer when the only information I have for the core steel are curves for Watts Loss per Kg and Peak Magentic Field strength(A/meter) for any given value of flux density. As far as I can see, using the...
Dear experts
How do I go about calculating what the power factor is of a 1500VA transformer off-load and at full load (resistive)
Also how would I go about calculating the values of PFC capacitors connected in parallel with the primary to improve the power factor if it is bad?
Many thanks

Dear All
Can anyone help me in calculating the total primary current of a transformer. The magnetizing current lags the secondary load current referred to the primary, and the total primary current is the vector sum of the two components. How do I find the mag current angle of lag and also once...
Hello All
I was wondering if anyone knows of a reasonably accurate way to calculate the leakage inductance of toroidal windings in small (<100KVA)power transformers. I have come accross plenty of information relating to conventional EI core designs, but to date I have found absolutely nothing...
