The quality of the electrical equipment protection pad depends first and foremost on the type of primary converters used to control the diagnostic parameters. Therefore, the question of designing and studying the parameters and capabilities of modern transducers, such as the lambda diode, is relevant.
The purpose of the study is to analyze the volt-ampere characteristics of the complementary pairs of transistors and to determine the parameters and limits of its use as a converter.
The scientific work is devoted to research the primary converter characteristics and capabilities, based on lambda-diode analogue which is used to monitoring diagnostic parameters in electrical equipment protection devices. The advantage of the lambda-diode is possibility to obtain volt-amps diagram with a negative-resistance section, and the disadvantage is impossibility to regulate or increase the width of its natural volt-amps diagram, so their analogs based on different circuitry principles are used. In this research were consider a lambda-diode analogue based on FET-transistor, which makes it possible to vary the width of the volt-amps diagram with negative resistance. This property can be used in protection circuits. The task is to research volt-amps diagram the different complementary transistors pairs of analogue have and to determine their parameters and limits to use as a primary converter. Electrical circuit and a test procedure were compiled as well. Based on researching results of different transistors types it is determined the type of transistor practically does not affect the parameters of the VA-diagram. The volt-amps diagram of analogue does not change when combining the drains or sources of FET-transistors. There was defined a relationship between resistance of voltage divider, the applied voltage and their influence on width the negative resistance section of VA-diagram.
