Abstract
Oscilloscopes can be used as an instrument of current
waveform wieving devices with current sensors which generate
voltage equivalent (at a certain scale) to measure current.
Rogowski Coil, one of the current sensor types, attracts great
attention in the last years, especially in the power electronics and
electromagnetic compliance tests. In a Rogowski coil, the seconder
is the coil itself and the primer is the conductor which passes
through the coil. In this sensor, seconder resistance is connected,
just to suppress the coil resonances in higher frequency. To obtain
the current waveform from the secondary voltage, this voltage
must be integrated firstly. In this work, a wideband active
integrator circuit was designed which provides integration by
using an inductor element and a resistor. A measuring system of
the designed and implemented circuit was formed and simulated
with Rogowski Coil which is made by cutting a copper tube.

Abstract
Osiloskoplar, akım ölçmek için, gerilim karşılığını (belirli bir
ölçekte) üreten akım algılayıcıları ile beraber akım dalga şeklini
görme düzeneklerinin bir elemanı olarak kullanılabilir. Akım
algılayıcı çeşitlerinden biri olan rogowski bobini son yıllarda
özellikle güç elektroniği ve elektromanyetik uyumluluk
testlerinde çok ilgi çekmektedir. Rogowski bobinlerinde sekonder
kısmı bobinin kendisidir, primer ise bobin içinden geçen
iletkendir. Bu algılayıcılarda sekonder direnci sadece yüksek
frekans bobin rezonanslarını bastırmak için bağlanır. Sekonder
geriliminden akım bilgisini elde etmek için önce bu gerilimin
entegre edilmesi gerekir. Bu çalışmada entegrasyonu bir
endüktans elemanı ve direnç ile sağlayan geniş bantlı bir aktif
entegratör devresi tasarlanmıştır. Tasarlanan ve gerçeklenen bu
devrenin bakır bir tüp kesilerek elde edilen Rogowski Bobini ile
birlikte ölçüm sistemi oluşturulmuş ve simülasyonları yapılmıştır.
