Abstract
Inventia se refera la tehnica masurarii si poate fi utilizata pentru masurarea rezistentei liniare a conductorului izolat.Dispozitivul contine un generator de semnal de masurare conectat cu o borna de iesire la masa, primul contact capacitiv amplasat adiacent conductorului masurat, un amplificator conectat cu intrarea la primul contact capacitiv, un rezistor comandat si un convertor de rezistenta negativa conectat cu o borna de iesire la masa, iar cu bornele de intrare - la rezistorul comandat, precum si un organ de nul comandat in faza, conectat cu iesirea la intrarea indicatorului de nul, cu intrarea de semnal - la iesirea amplificatorului, iar cu intrarea de referinta - la punctul circuitului convertorului de rezistenta negativa in care semnalul este in aceeasi faza cu curentul din conductorul masurat. Dispozitivul contine suplimentar al doilea si al treilea contact capacitiv, amplasate adiacent conductorului masurat, conectate, respectiv, la a doua borna de iesire a generatorului de semnal si la o doua borna de iesire a convertorului de rezistenta negativa.Primul contact capacitiv este amplasat intre al doilea si al treilea contact capacitativ, totodata amplasamentul primului contact este determinat de distanta de la el pana la contactul al treilea. ŕThe invention relates to the measurement technique and can be used to measure the linear resistance of the insulated conductor. The device contains a measurement signal generator connected with an output terminal to the ground, the first capacitive contact located adjacent to the measured conductor, an amplifier connected to the input to the first. capacitive contact, a controlled resistor and a negative resistance converter connected with an output terminal at the ground, and with the input terminals - at the controlled resistor, as well as a zero-phase commanded phase connected to the output at the zero signal input, with the signal input - at the output of the amplifier, and with the reference input - at the point of the negative resistance converter circuit in which the signal is in the same phase as the current in the measured conductor. The device additionally contains the second and third capacitive contacts, located adjacent to the measured conductor, connected respectively to the second output terminal of the signal generator and to a second output terminal of the negative resistance converter. The first capacitive contact is located between second and third capacitive contact, at the same time the location of the first contact is determined by the distance from it to the third contact. à
