Hi,

I am trying to plot the currents and voltages in the following circuit but not sure how well I am doing. I have been given some information that the inductor coil angle is 78 degrees. Have I placed the currents correctly? I believe the inductor current should lag the Inductor voltage by 78 degrees and the capacitor current should lead the capacitor voltage by 90. Does my vector diagram look correct based on the schematic below?

The values I have are:

Vc – Capacitor Voltage = 195V
VOD – Open Delta = 110V
VREL – Relay voltage = 123V

And the current through the metrosil is 37mA at 123V.

Please see attached diagrams:
