There is 3phase power cable from 1 point to the other point
which is 100m away. Two point equipped with power meter and
recorded 1st point is 205kW while the 2nd is 202kW and each
phase average carry 400amps. To calculate the resistance of
the 3phase power cable, is the formula using will be P=I2R?
When we change the tap position of 10MVA transformer it
suddenly tripped with Out of step indication and also with
Static differential relay indication, Transformer Bucholz
relay indn and Low oil level indication. Before 1 week the
same problem occured by changing the tap position. but at
that time only oltc bucholz relay activated. After testing
the TxR Relay team & PET team cant find any solid reason.
The values are ok also. So plz answer wat's the reason for
this incident? anybody plz help.
