(Summary description)Put the tap position on the nominal tap. Connect the 4-core cable with MCB on the high-voltage side and the low-voltage side, and make sure that the low-voltage side is open. Then cycle between the HV red phase and the LV red phase. Inject 415V on the high side (with the MCB on) and measure the voltage on the low side of each phase. Record the results and draw a vector set of transformer windings to the appropriate scale based on the test results.
