Near the HT bushing on the top cover you can find it which
is covered by a plate.This is used for measuring Tan-delta

Answer / raghavendran.r

I have not heard about tan-delta tap but there is tan delta
testing of PT.It is used to measure the insulation resistance
between phases and between phase and earth and also IR values between in the bushings.

why should the lowest unit of a testing transformer ( cascaded transformer ) have higher power rating??

I have a current transformer with 1 main reading meter with transformer outside the building and a control panel having 5 CT reading meters with black round coils inside the building. I want to know, A) when current pass through the Transformers, will the current be reduced or be the same and after that B) when current pass through the CT meters with black round coils, will the current be reduced or be the same. C) in the above process will the reading of the main meter be same or different, from the total reading of all the 5 CT meters.

How do I know if a transformer is saturated? I am doing the simulation of the saturation of a transformer, but what parameter tells me when a transformer is saturated? How do you calculate? is on the plate?, there is a rule that can help me? How could model? I understand the saturation occurs when the flow can no longer bind to the other winding, this is given to certain current, this current is the same that appears as the highest in the bale of features? Thank you for your help Eduardo Alvarez Guatemala
