DEVICE FOR MEASURING WEBER-AMPERE CHARACTERISTICS OF ELECTRICAL DEVICES Russian patent published in 2017 - IPC G01R33/12 

FIELD: measuring equipment.

SUBSTANCE: device for measuring weber-ampere characteristics of electrical devices, containing a power source, a magnetizing winding applied on the test sample, a measuring shunt. A scaling device, an amplifier, a differentiator, a null-detector, an analog-to-digital and a digital-to-analog converter are connected to the output of the power source, six amplitude detectors, a commutator switch, the first and second multiple band-pass filter, the first and second sample-and-hold devices, a personal computer, a model unit. The method of the natural-model experiment for determining web-ampere characteristic of an electrical product forms the basis of the developed device for measuring web-ampere characteristics of electrical devices.

EFFECT: expansion of the functionality of the device for measuring web-ampere characteristics of electrical devices.
