Abstract

Penggunaan driver motor dalam jumlah besar yang tidak dilengkapi peredam harmonisa internal dapat menghasilkan harmonisa dalam sistem kelistrikan. Driver motor di CCAI Surabaya Plant dalam jumlah yang besar telah menghasilkan harmonisa yang mendistorsi sinyal tegangannya dan mengakibatkan kerusakan peralatan listrik dalam jumlah yang besar. Selain itu besar frekuensi yang dihasilkan juga sangat besar sehingga merusak kapasitor bank yang menimbulkan kerugian yang besar. Filter RCL dapat mengatasi harmonisa pada sistem kelistrikan. Filter RCL adalah filter pasif seperti lowpass filter, single tuned filter, dan high pass filter. Pemasangan filter tersebut dapat bermanfaat untuk meredam harmonisa yang dapat mencegah kerusakan kapasitor bank dan peralatan listrik lainnya karena distorsi sinyal listrik jauh berkurang. Selain meredam harmonisa, filter RCL dapat memperbaiki faktor daya karena memberikan daya reaktif (kVAr) pada sistem kelistrikan. Karena dapat menjadi sumber daya reaktif pembatasan filter juga harus diperhitungkan agar tidak menimbulkan over voltage pada bus di sistem kelistrikan. Diharapkan dengan pemasangan filter RCL di sistem kelistrikan CCAI Surabaya Plant dapat memperbaiki sistem secara keseluruhan dan mengurangi kerusakan peralatan listrik yang sering terjadi. ============================================================================================================= The use of motor drives is in great numbers must be accompanied internal silencer harmonisa can produce harmonisa in electric system. Motor drives at CCAI Surabaya Plant in great numbers has produced harmonisa that distort the signals of voltages and result in damage to electrical equipment in large quantities. Furthermore, great frequency produced too large and highly damaging capacitor bank to a great disadvantage. A filter RCL can overcome harmonisa on electric system, A filter RCL is a filter passive lowpass filter , single tuned filter , and the high pass filter. The installation of filters can be beneficial to quell harmonisa that can prevent damage to banks of capacitors and other electrical equipment because of distortion of an electrical signal much reduced. In addition to dampen harmonisa, filter RCL can fix the resources for giving a reactive power ( kVAR ) on electric system. RCL filter can be reactive power source. The filters also be taken into account in order not to over voltage on a bus in electric system. It is expected with the installation of RCL filters ccai electric system in surabaya plant can improve the whole system and reduce damage to electrical equipment often happens.
