Yaqin vaqtgacha sanoat korxonalarining tarqatish moslamalarida, shu jumladan elektr stantsiyalarida elektr qiymatlarini o'lchash elektromagnit oqim transformatorlari yordamida amalga oshiriladi. Magnit zanjirning magnitlanish egri chizig'ining chiziqli bo'lmaganligi sababli, bunday oqim transformatorlari asosan o'tish rejimlarida qoniqarli metrologik xususiyatlarni ta'minlay olmaydi, shuningdek, oqim transformatorining magnit pallasi qisqa tutashuv oqimining aperiodik tarkibiy qismi bilan chuqur to'yinganida qisqa tutashuv oqimlari paydo bo'lgandan keyin. Maqolada optik tolali oqim transformatoridan foydalanish taklif etiladi, uning dizayni tufayli yuqorida ko'rsatilgan kamchiliklarga ega emas va elektr energetikasida, yuqori kuchlanishni o'lchash texnologiyasida, o'rni himoyasi va avtomatlashtirish sohasida ishlatilishi mumkin. Texnik natija uzoq muddatli foydalanish sharoitida o'lchovlarning ishonchliligi va barqarorligini oshirishdan iborat. Maqola "O'zbekenergo"AJ obyektlarida o'tkazilgan tajriba materiallari asosida tayyorlangan.
