Description

Предметом изсбретени   вл етс  устройство дл  измерени  тангенса угла потерь по гзеличниам актнвноГ; и реактиЕпой слагаемых тока, протекающего через испытуемый диiTeKTpi .ic.The subject of the exemption is a device for measuring the loss tangent of hazardous gas; and reacting the current to the currents flowing through the subject diTeKTpi .ic.

Устройство отличаетс  тем, что лпгнитоэлехтрпческий прибор, измер ющий ток, включеп через синхронный переключатель, обмотка возбуждени  которого может быть включена либо через импеданц, обеспечивающий сдвиг фазы колебапи  переключател  на четверть периода по отношению к питаю.щему напр жению с целью измерени  реактивной слагаемой тока, либо lepes и.мпеда 1ц, обеспечивающий совпадсиие фазы колебаний переключател  и питающего напр же ;:1Я с иель10 измерени  активной слс1гаемо11 тока.The device is distinguished by the fact that a battery-measuring device, measuring current, is switched on via a synchronous switch, the excitation winding of which can be switched on either through an impedance, providing a quarter-shift of the switch oscillator phase relative to the supply voltage, in order to measure the reactive component of the current, or lepes impeda 1c, which ensures the coincidence of the phase of the oscillations of the switch and the power supply; 1: 1 with the help of 10 measurements of the active current of the current.
