how to measure inductance
Hi
I am trying to measure the inductance of current transformer (200/5 A , 33 KV). Initially I use LCR meter, it has three frequency ranges. It gives very different values in those frequencies. Later I used a simple voltmeter and ammeter method using the Z =V/I. This method gives results depending upon the input level. If we take the saturation point only V remains fixed and current not. I am confused, Is there anyway to find the CT inductance without error ? .
I think L is independent of Frequency and XL is depend on frequency , Is that correct ?
Please let me help if there is any solution for this problem
