td8545 comprehensive testing apparatus for magnetic properties of electrical steel sheets

- it's used eps or sst to measure the ps, bm, jm, hm, br, hc, μi, μm of silicon steel sheets.

- and draw magnetic curves. f:dc 3hz~20khz. hmax: 30ka/m
- other testing functions: harmonic influence, complex waveform, dc bias.

application

- uut: grain-oriented / non-oriented silicon steel, transformer, iron core.
- epstein frame method: measuring sample sheet during 3hz…1khz…10khz…20khz.
- single sheet method: measuring 500 mm*500 mm sheet with permeameter. support m.c method and h-coil method, or the combination.
- measuring ac parameter: hm, bm, jm, ps, ss, drawing hysteresis loop, loss curve, permeability curve.
- measuring dc parameter: hm, bm, jm, br, hc, μi, μm, drawing magnetizing curve, hysteresis loop, permeability curve.
- options:
harmonic function: excitation output can load 2-63 times harmonic wave.
complex wave: support customizable waves: triangle, staircase, square etc.
dc magnetic bias test.
