ECOLOGY-PROOF METHOD FOR TESTING PROTECTION OF ELECTRIC CIRCUITS OF ELECTRIC EQUIPMENT AGAINST ELECTROMAGNETIC FIELDS

摘要

FIELD: electronic equipment. SUBSTANCE: method involves application of small-power sine signal of frequency of external interfering electromagnetic field to excite tested electric circuit, measurement of electromagnetic field which is emitted into air, comparison of this measurement to maximal value of given external electromagnetic field and judging protection level of circuit element by calculation. Electric isolation of tested circuit and measuring equipment is achieved by circuit excitation through optical cable. EFFECT: increased ecological safety, mobility, increased efficiency of tests. 2 cl, 2 dwg
