Training Switchgear
INTRODUCTION
Switchgears dan circuit breakers merupakan komponen penting dalam sistem distribusi listrik dan pengoperasiannya secara signifikan mempengaruhi operasi keseluruhan sistem. Pengoperasian medium voltage switchgear, dan testing adalah masalah yang berkaitan dengan listrik, dan voltage circuit breakers type high, medium, dan juga akan ada cakupan switchgear tegangan rendah (low voltage switchgear).
Pelatihan ini akan memberikan landasan menyeluruh dalam teori switchgear dan standard-nya. Peserta akan mendapatkan pemahaman mengenai aplikasi yang tepat, instalasi dan maintenance terhadap peralatan penting ini dengan penekanan utama pada aspek safety. Pelatihan akan bersifat komprehensif dan praktis, yang menekankan switchgear tegangan menengah (medium voltage switchgear) yang mewakili sebagian besar switchgear diinstal pada sistem distribusi listrik. Komponen sistem proteksi daya lainnya akan dibahas juga untuk memastikan bahwa switchgear dipahami dalam konteks yang benar.
