6.Test and operation method
A: Single-phase measurement method, see Figure 7 below:
Figure 7
B. The wiring of the assisted magnetic method is shown in Figure 8~10 (applicable to
Y(N)-d-11 connection group).When measuring the low-voltage side of a large-capacity
transformer, if the maximum current of the DC resistance tester is relatively small under
existing conditions, or in order to speed up the measurement, you can choose the
magnetic method to measure. In the figure below, Figure 8, Figure 9, and Figure 10 are
