Zusammenfassung:The invention is devoted to electrical engineering, and it can be applied in diagnostics. The goal of the invention is to extend functional possibilities of control devices. The device contains single-pole pulse generator 1, switch 2, magnetically connected with primary winding 3, magnetically connected with secondary winding 5, and core 4. One of the windings and clamps are connected to oscilloscope 6, but the second clamp of generator 1, the second clamps of windings 3 and 5 and general clamp of oscilloscope 6 is connected to zero-point. The generated rectangular impulse with high frequency is determined with pulse front and duration. It gives the possibility to determine the windings short circuit, break and insulation conditions. Izgudrojums attiecas uz elektrotehniku un to var izmantot diagnostikā. Tā mērķis ir paplašināt kontroles iekārtas funkcionālās iespējas. Iekārta satur impulsu unipolāro barošanas ģeneratoru 1, slēdzi 2, magnētiski saistītu primāro tinumu 3, magnētiski saistītu sekundāro tinumu 5 un serdeni 4. Viens no tinumu izvadiem ir pievienots osciloskopam 6, bet barošanas ģeneratora 1 otra spaile, tinumu 3 un 5 otrie izvadi un osciloskopa 6 kopējā spaile ir pievienoti nullpunktam. Ģenerētie taisnstūra impulsi ar paaugstinātu frekvenci nosaka inducēto impulsu fronti un ilgumu. Tas dod iespēju noteikt tinumus īsslēgumu, pārrāvumu un tinumu izolācijas stāvokli.
