In this thesis; Electromagnetic Compatibility (EMC) of Electric Power Quality
Monitor developed within the scope of National Power Quality Project has
been investigated according to EN 61326 standard. Both immunity and
emission tests have been carried out in EMC laboratories of ELDAŞ and
ASELSAN for the device under test. Necessary counter measures such as
using electromagnetic interference (EMI) filters and transient voltage
suppressors, shielding the case of device with EMI protective materials have
been taken to satisfy the immunity and emission limits defined in the
standard for the device, and their success have been verified by laboratory
tests. This research work has been fully supported by Public Research Grant

Committee (KAMAG) of TÜBĐTAK within the scope of National Power Quality
Project (105G129).

Bu tez çalışmasında; Güç Kalitesi Milli Projesi kapsamında geliştirilen Elektrik
Güç Kalitesi Ölçüm Cihazının elektromanyetik uyumluluğu (EMU) EN 61326
standardına göre incelenmiştir. Deneyden geçirilen cihazın bağışıklık ve
emisyon şartlarını kapsayan testler ELDAŞ ve ASELSAN EMC
laboratuarlarında gerçekleştirilmiştir. Cihaz için tanımlanan bağışıklık ve
emisyon seviyelerine göre elektromanyetik girişim filtreleri ve geçici gerilim
değişimi önleyiciler kullanmak ve cihaz kutusunu elektromanyetik girişim
önleyici maddelerle kaplamak gibi gerekli önlemler geliştirilmiş ve bu
önlemler laboratuvar testleri ile sınanmıştır. Bu araştırma tamamen, Güç
vi
Kalitesi Milli Projesi (105G129) kapsamında TÜBĐTAK’ın Kamu Araştırmaları
Grubu (KAMAG) tarafından desteklenmiştir.
