    Please could someone assist with Phasor Diagrams? I need to draw a phasor diagram to indicate the phase voltage in a 3 phase balanced star connected resistive load and identify the phase angles etc.

    I understand the concept of a phasor diagram however need a little assistance to get started.

    Thanks a lot

    Three vectors seperated at an agle 120 to one another starting from the origin represents phasor diagram. You have to mark a rotation direction for the vectors in anti-clockwise direction and denote it by ω which will be the angular velocity. Name all the vectors like VA,VB & VC. As it is a resistive load mark currents in phase with these vectors as IA,IB & IC.

    sorry to describe this, i don't know how to draw on this page.
