Analysis on the Transfer Characteristics of Rogowski-coil Current Transformer and Its Influence on Protective Relaying

where, V o is the measured voltage across the terminal capacitor ( C t ). It is worth to mention that C t is taken as 220 nF [28] when no terminal components are used. From this figure, using terminal capacitor gives a higher output voltage magnitude at low frequencies as compared with the use of terminal resistor as well as providing the best reduction for high‐frequency components as previously stated in Section 2.…”

This study presents a technique for power frequency AC voltage measurement. The proposed technique utilises a capacitor having a low capacitance in addition to a double wound Rogowski coil. This technique depends on capacitor current measurement using the double wound Rogowski coil. The voltage across the capacitor that connected in parallel with the system at which AC voltage is intended to be measured is reconstructed. The proposed technique is experimentally evaluated by designing the measurement system and using a digital signal processing board for the reconstruction processes. Moreover, the experimental results based on Rogowski coil measurements are compared with those obtained from reference techniques. Finally, the obtained results validate the efficacy of the proposed technique in power frequency AC voltage measurement.

“…Koil Rogowski telah lama digunakan dalam aplikasi daya listrik untuk mengukur frekuensi rendah sinusoidal dan arus transien (7) , pengukuran potensial magnetik dan untuk berbagai aplikasi sensor arus: relay pelindung (protective relaying), pengukuran arus tinggi, arus impuls (impuls current), dan arus transien dalam industri daya listrik, pengelasan tahanan dalam industri otomotif, fisika plasma dan lainnya (8) . Beberapa keuntungan koil Rogowski antara lain adalah kesederhanaan dalam desain dan operasi, lebar-pita frekuensi yang luas dan tanggap dinamik yang baik dan tidak ada kejenuhan magnetik, biayanya murah dan presisi (9,10,11) .…”

ABSTRAK PENENTUAN ARUS SPOT PLASMA DAN ARUS PLASMA LUCUTAN BUSUR PADA SISTEM SUMBER ELEKTRON KATODE PLASMA MENGGUNAKAN TEKNIK KOIL ROGOWSKI. Telah dilakukan eksperimen uji fungsi sistem elektrode ignitor dan sistem elektrode generator plasma untuk menentukan arus spot plasma dan arus plasma lucutan busur dengan teknik koil Rogowski. Sistem elektrode ignitor yang mendapat catudaya dari sistem IDPS dapat menghasilkan arus spot plasma 11,68 ampere dengan lebar pulsa sekitar 33 ms; nilai tersebut lebih besar dari rancangan mungkin karena komponen elektronik yang digunakan pada sistem IDPS tidak sesuai dengan yang direncanakan. Untuk sistem elektrode generator plasma yang mendapatkan catudaya dari sistem ADPS mampu menghasilkan arus plasma lucutan busur sekitar 103,15 ampere dengan lebar pulsa sekitar 96 ms, dan nilai ini sesuai dengan yang direncanakan. Berdasarkan nilai arus plasma lucutan busur ini dapat ditentukan rapat elektron plasma, yaitu sekitar 10,12 ´ 1019 elektron/m3 dan dengan nilai kerapatan elektron plasma ini, sistem elektrode ignitor dan generator plasma cukup baik jika digunakan sebagai sistem sumber elektron katode plasma.
