CONNECTING CTs:
Be sure of connecting each CT to the related phase input with the correct polarity. Mixing CTs between
phases will cause faulty power and pf readings.
Many combinations of incorrect CTs connections are possible, so check both order of CTs and their
polarity. Reactive power measurement is affected by incorrect CTs connection in similar way as active
power measurement.
CORRECT CT CONNECTIONS
Let’s suppose that the genset is loaded with 10 kW on each phase. The load Power Factor (PF) is 1.
Measured values are as follows:
kW
