Only use these circuits in symmetrical grids. Note that you must always take
the W1 voltage and current measurements on the low-voltage side of the
transformer.
▪ W1: Voltage measurement and current measurement for the power calcu-
lation and hot-spot calculation on winding 1
▪ W2: Current measurement for hot-spot calculation on winding 2
▪ W3: Current measurement for hot-spot calculation on winding 3
