Answer / guru

Role of energy meters at Distirbution transformer is to
calculate the total output power and check with the sum of
the energy readings recorded at indvidual energy meters of
that particular distribution transformer.

This is used for calculating both technical losses and non
technical losses and technical losses from Distribution
transformer ~ consumer should not exceed 4 - 5 % of the
total output power of the Distribution transformer. For
calculating Technical losses line length , type of
conductor, no. of joints etc. in the line are taken into
account

Hi Suppose we have a wye/wye transformer which is grounded at both sides,in this situation, do we have ay ground transformer? in other words, ground transformer can do any thing more (while we have nuetral wire in both sides)? As the last question, what about 3rd harmonic? we have two choices: first using wye/delta transformer + ground transformer and second using wye/wye earthed connection.in the former choice, we dont have 3rd harmoonic at the secondary side but what about Yn/yn conection? do we suffer from 3rd harmonic in the Yn/yn connection?
