Re: Calculating Clearances in Air and Transformer Oil

There is the extensive list of subjects that related to clearance term in power transformers (insulation clearance, thermal clearance, installation clearance,…).
For example, do you know how insulation clearance influenced to transformer impedance? In high power transformer, the high voltage requires large internal clearances which mean increasing size and leakage reactance.Indeed increased HV to LV clearance has the effect of increasing the reactance, and hence the impedance.
