2.1 Current measurement
When installing the current converter, care should be taken to ensure that the load
current and capacitor-current flows through it. The outputs of the compensation network
must be installed behind the current converter (in the direction of current flow). If the
device is connected up via sum-current converters, the overall conversion ratio is
entered.
2.2 Programming of phase-correction - e.g. connection directly L-L (400V)
Adjustment of phase-correction between voltage and current in the meas. system is done
in expert mode 1
Example :
Meas.current: L1
Meas. voltage: L3-L2
Phase U/I [ 90°]
