Abstract

ABSTRAK

Pelayanan energi listrik hingga sampai ke konsumen tidak lepas dari gangguan. Sebagian besar gangguan yang terjadi merupakan gangguan tidak seimbang (tidak simetris), yang terdiri dari gangguan 1 fasa ke tanah, dua fasa ke tanah dan gangguan fasa ke fasa. Gangguan tidak seimbang yang terjadi pada busbar dapat menyebabkan: kerusakan pada alternator, berkurangnyabatas-bataskestabilansuatusistemtenaga, rusaknyaperalatan danteganganrendah yang disebabkanolehhubungsingkat, ledakan-ledakan yang mungkinterjadipadaperalatanyang mengandungminyakisolasi, danterpecahnyadaerahpelayanankarenarentetantindakanpengamananoleh system proteksi yang berbeda – beda yang dikenalsebagai “cascadingâ€.
