The value of the loads fluctuate drastically during an LCM test when the capacitors are connected:
The value for each phase will differ in size with an incorrect value (+/-) on the Mains KVAr as well on the
polarity screen:
The phase angle from L1-L2 will be at 120º & in the incorrect direction on M
screen:
In addition L2-L3 will increase at an angle of 240º & increases at another 240º from L3-L1, instead of a 120º. You
will also notice that I
