For a three-phase measurement according to connection type 3P4W (four conductors,
unbalanced load, without voltage transformers, with three current transformers), accuracy
class 1, primary rated current 100 A, secondary rated current 1A, three window-type
transformers are recommended (4NC5117-0CC20).
Note
When measuring the complete machine, it is recommended that the current is sensed directly
after the main switch. For the voltage tap, please observe the usual protection/fusing.
