Answer / k.prakashchandra
The voltage input to almost all energy meters is 110 V line
to line ,which is the secondary voltage of PTs. You can use
them for all system voltages by applying the correct MF .

Answer / mu
we can use any meter at this point as we have to only
change CT & PT's before commissioning,
I have used 11kv meter in 33 kv installation with similar
changes, usual practice done by SEB's across india when
supply voltage changes for any project.

Answer / vimal patel
All digital meters can be used at any place like 220kv,66 kv , 33 kv and also 11kv..but first u have to see that metering range of Voltage and Current so u have to adjust that all phase Ct and PT Ratio upto that meter range and than find that MF ( Multiplying factor ) to get Unit.

The voltage input to both the meters is 110 V.So, you can
use and pre-set meter constant is to be considered

Answer / saleem
The Digital Meter can be used with proper setting, however
the analog meter can not be used because its dial is
calibrated for 11KV.
