Answer / k.prakashchandra

No effect on ammeter.In EM type Watt meter and energy meter
the readings reversed.In ETVM import and export interchange.

Answer / vels

one phase is reversed then the Energy meter will not give correct reading
but 3 phases are reversed then the current direction shown are wrong and the reading of MW ,MVAR are showing import instead of export

Answer / sureshkumar

incase protcetion CT not protective the equipment, so direction is must.

Answer / kj

It only has an effect where the direction of current flow
is important. For example monitoring import and export of
power.
