C – CT POSITION CHECKING
In case of wrong cos phi reading by the controller, it is necessary to check its position to make sure it is
properply located on phase L1 and upstream all the loads to be compensated.
To do :
By means of a voltmeter check there is zero voltage between phase L1 of the network where CT
is fitted and phase L1 of capacitor bank
