The tester could select the silicon iron quickly because it applies the method of National Standard GB/T13798-92, it could test the iron loss of tested material by using just one piece of silicon steel.

Being sine wave field power supply installed internally, the SCM control technique combines with A/D, the tester could test different thickness of oriented (1.7T) and non-oriented (1.5T) hot-rolled or cold-rolled silicon steel.

The harmonics won’t be influenced as the copper loss will be eliminated in the result of test, also the magnetic flux sine could be maintained in testing.
