Through the advancement in computers and technology, it is now
feasable to have the skills and accuracy capability of the laboratory
without the cost. This new design tests all grades and gauges
of electrical steel sheet per ASTM A-343, wattmeter-ammeter-voltmeter
and 25cm Epstein frame method. It is recommended for motor and
transformer producers and all users of electrical steel.
This is a fast, accurate, fully automatic tester that determines
the AC magnetic properties of flat rolled electrical steel at
60 and 50 Hertz power frequencies, complying exactly with the
ASTM A-343 test method standard. It measures core loss, exciting
power, magnetic field strength and permeability at inductions
(B) 10 to 18 Kilogauss (kG). The MTE-2 is a complete stand-alone
tester with all hardware and software ready for immediate measurements.
Its high accuracy is accomplished by use of negative voltage feedback
which maintains undistorted sinusoidal waveform flux within the
test sample. Furthermore, it uses computer digital feedback to
set induction levels precisely.
