this is a instrument, which measures kvah and also kva of maximum demand. it consists of a kwh meter and a reactive kvah meter in the common case with a special summator mounted between them. the summator is driven by both the meters through a complicated gearing, which makes the summator to register kvah at all power factors.
if a damaged 500kva transformer with %impedance 2.6 is
replaced by two transformers of 250Kva with different %
impedance will they be able to catter the load. what will
be the ratio of load on the two transformers if the %
impedance is in the ratio 1:2
