Automatic measurement of the dynamic magnetic hysteresis loop of oriented and non-oriented silicon steel under the condition of 45Hz~1kHz, accurate measurement of the static magnetic characteristic parameters such as amplitude permeability μa, loss angle δ, specific total loss Ps, remanence Br and coercivity Hc. With special testing fixture, it can directly measure the silicon steel, permalloy, amorphous and nm crystal stator core and transformer core .
Windows measurement software applied simply. The product conforms to China National Standards GB/T 3655-2000, GB/T 13789-92 and international standard IEC 404-2, IEC 60404-3, IEC 60404-6.
The controlling of computer and A/D sampling replace the traditional analog bridge, frequency meter, ammeter, voltage meter, power meter, the whole testing process is automatic completed.
--- Testing sample varieties: hot rolling, cold rolling silicon steel materials, permalloy, amorphous and nm crystal.
--- Testing sample shapes: Ring, CD,Rect,EE and EI closing samples.
--- Open circuit samples adopt Epstein Square to form closed magnetic circuit, it can also select sample Silicon steel permeameter, such as MT30mm×300mm, MT500mm×500mm etc.
--- Closing sample can be put under direct winding measurement, finished transformer can be also put under direct measurement.
--- Sample (iron core), magnetizing coil (N1) and measuring coil (N2) form a no-load transformer.
--- Power source and sampling amplifier put into a chassis which make the interface very simple: a RS232 interface connect to the computer, the second voltage signal connect to high speed A/D card.
--- Adopt volammetry and digital integration to measure dynamic hysteresis loop, it can accurately measure dynamic magnetic characteristic parameters such as μa, δ, Ps, Br and Hc, etc.
--- Automatic and continuous measurement up to 255 testing points, the testing time of every testing point is about 5 seconds, fixed-frequency, fixed Bm or fixed Hm optional in multipoint test.
--- Powerful function of the software, the technical request to the testing staff is very low.
--- Output is sine wave, output distortion is very low and nothing to do with the load, ensure the accuracy of the test result.
--- I/U/B sampling waveform
--- B(H) hysteresis loop
--- B(H) magnetic hysteresis cycle cluster
