Description
Изобретение относитс к фазоизмерительной технике и может быть использовано при создании приборов дл измерени сдвига фазы между напр жением и током.The invention relates to a phase-measuring technique and can be used to create instruments for measuring the phase shift between voltage and current.
По основному авт.св. № 331339 известно устройство дл измерени сдвига фазы между напр жением и током , содержащее индикатор, два резистора , транзистор, стабилитрон и два полупроводниковых диода, соединенных встречно-параллельно и последовательно .с,нагрузкой, причем параллельно диодам подключен переход эмиттер-база транзистора, а па)аплельно источнику переменного напр жени присоединены последовательно соединенные резистор и стабилитрон , катод которого через второй резистор подсоединен к коллектору транзистора, а и1здикатор соединен с коллектором транзистора и катодом стабилитрона Fl.According to the main auth. No. 331339, a device for measuring the phase shift between voltage and current is known, which contains an indicator, two resistors, a transistor, a Zener diode and two semiconductor diodes connected anti-parallel and in series with a load, and the emitter-base of the transistor is connected parallel to the diodes, and pa), in series with the alternating voltage source, are connected in series a resistor and a zener diode, the cathode of which is connected to the collector of the transistor through the second resistor, and an indicator is connected to the tra collector ican and the cathode of the zener diode Fl.
Недостатком известного устройства вл етс невозможность определени характера нагрузки (ёмкостный или индуктивный), так как это устройство определ ет толькоабсолютное значение угла сдвига фазы.A disadvantage of the known device is the impossibility of determining the nature of the load (capacitive or inductive), since this device determines only the absolute value of the phase angle.
Цель изобретени - расширение функциональных возможностей устройства путем определени характера нагрузки .The purpose of the invention is to expand the functionality of the device by determining the nature of the load.
