Answer / n panja

Linear element are those elements whose voltage current relationship is linear. For example voltage-current relationship of a resistor is V=IR, which is a linear equation. Similarly for an inductor the relation is V=L*dI/dt, which is again a linear differential equation. So these are the examples of linear elements. On the other hand diode, transistor have non-linear voltage current relationship, so they are non linear elements.

I have 11KV/415V power distribution transformer. I have found unbalance current in LT (415V) side. Also observed that unbalance voltage (3V) at LV side due to HV side unbalance voltage. What should I check for this? Also, the same LV side load can run in balance on captive power.
