Изобретение относится к электроизмерительной технике и может быть применено для измерения емкости в многопредельных переносных и комбинированных приборах. Устройство для измерения емкости электрических конденсаторов содержит источник постоянного тока, переключатель питания, измеритель тока, полевой транзистор, набор образцовых конденсаторов, измеряемый конденсатор, переключатель пределов измерений, переключатель "измерение", резистор в цепи истока и резистор в цепи стока полевого транзистора. Применение данного устройства,основанного на принципе измерения напряжения на конденсаторе, заряженном калиброванным электрическим зарядом, позволит увеличить точность измерения емкости электрических конденсаторов.The invention relates to electrical engineering and can be used to measure capacitance in multi-range portable and combined devices. A device for measuring the capacitance of electrical capacitors contains a DC power source, a power switch, a current meter, a field-effect transistor, a set of sample capacitors, a measuring capacitor, a switch for measuring limits, a measurement switch, a resistor in the source circuit, and a resistor in the drain circuit of the field-effect transistor. The use of this device, based on the principle of measuring the voltage on a capacitor charged by a calibrated electric charge, will increase the accuracy of measuring the capacitance of electric capacitors.
