Abstract

Iki fazli veya trifaze bir elektrik sistemindeki nötr kondüktördeki akimi düsürmek için bir aygit sunlari içermektedir: her fazin akimini veya voltajini ölçmek için araçlar (21,22,23); nötr kondüktördeki akimi ölçmek için araçlar (35); her fazdaki akimin veya voltajin nötr kondüktördeki akimla çogltilmasi için araçlar (31,32,33), faz voltajinin ve akimin çarpimini eksi bir geri gönderme döngüsü içindeki sarja geri beslemek için araçlar (42). Sözü edilen aygit ayrica sunlari içerebilir: ölçülmüs faz voltajlarini veya akimlarini kontrol sinyallerine dönüstürmek için ara birim araçlari (21,22,23); ve sözü edilen çogaltma araçlarinin çikisini alçak frekans filtrasyonu uygulayarak normalize etmege yarayan araçlar (107,109). Ayni zamanda nötr akimi düsürmek için bir yöntem açiklanmaktadir.It includes a device for reducing the current in the neutral conductor in a two-phase or three-phase electrical system: means for measuring the current or voltage of each phase (21,22,23); means (35) for measuring the current in the neutral conductor; means (31,32,33) for multiplying the current or voltage in each phase by the current in the neutral conductor, means (42) to feed the product of the phase voltage and current back into the charge in a negative return loop. Said device may also include: interface means (21,22,23) to convert measured phase voltages or currents into control signals; and means (107,109) for normalizing the output of said duplication means by applying low frequency filtration. A method for reducing the neutral current is also disclosed.
