\u2160: Bagaimana anda menguji rintangan lilitan transformator?<\/strong><\/p>\n\n\n\n

Rintangan lilitan trafo<\/strong> Pengukuran diperoleh dengan mengalirkan arus DC yang diketahui melalui lilitan yang diuji dan mengukur kejatuhan voltan merentasi setiap terminal (Hukum Ohm).<\/p>\n\n\n\n

Rintangan lilitan dalam trafo akan berubah disebabkan litar pintas pada lilitan, sambungan longgar, atau sentuhan yang semakin buruk pada penukar tap. Tanpa mengira konfigurasi, pengukuran rintangan biasanya dilakukan fasa ke fasa dan bacaan dibandingkan antara satu sama lain untuk menentukan sama ada ia boleh diterima.<\/p>\n\n\n\n

\u2161: Kaedah apa yang digunakan untuk mengukur rintangan lilitan?<\/strong><\/p>\n\n\n\n

Rintangan lilitan boleh diukur secara langsung dengan ohmmeter. Kaedah lain ialah mengira rintangan dengan mengukur arus melalui setiap lilitan menggunakan amper meter A apabila voltan dikenakan dan diukur dengan volt meter V.<\/p>\n\n\n\n

\u2160: How do you test the winding resistance of a transformer? Transformer winding resistance measurements are obtained by passing a known DC current through the winding under test and measuring the voltage drop across each terminal (Ohm’s Law). Winding resistance in transformers will change due to shorted turns, loose connections, or deteriorating contacts in tap changers.
