Answer Posted / gova
Diff relay compares the input current and output
current that flows through the equipment and if there is
any difference between them,then the relay will sense the
difference of two currents (called differential current)
and trip the equipment protected if the differential
current exceeds the setting.
diff relay used in transformer,Generator,lines,motors etc.
what is MDB.pl abbreviate it.

What is the loss of power of transformer 220kv/33kv,63/80mva of % imp12.05 at 80%load
FOR 16/20 MVA 132/33 KV ONAN/ONAF TYPE TRANSFORMER IT IS DESIGNED FOR 16 MVA WITH ONAN CONDITION.IT BECOMES 20 MVA UNDER ONAF CONDITION.LOAD LOSS IS GUARANTEED FOR 65KW AT 20 MVA AND % IMPEDANCE 13.75. PLEASE TELL US AT WHAT LOAD LOSS AND % IMPEDANCE IT SHOULD BE DESIGNED FOR 16 MVA AND WHAT WILL BE ITS EFFICIENCY AT 20 MVA?
we have consol make 3 phase servo stabilizer for cnc m/c. while installing the earth neutral voltage is 1.7 volts at stbilizer off condition and when stabilizer get on en voltage reaches 4.8 volts (new earthing is done and neutral is helthy condition all phase to neutral volts 440,442,441 v)why this happen.solution for cause.

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?
