1.5.3.2 Phase measurement between output current and an external current
The auxiliary metering current input can be used to measure the phase of an external current
(up to 10A) relative to the output current from phase A, B or C. To do this, connect the
external current to the aux metering “com” and “10A” terminals, and switch the mode switch to
“phase”. Select the desired reference phase output using the phase select switch.
The connection shown below will result in a measured angle of zero degrees. Note that the
TIMER MODE switch is set to phase A.
