Online Training – Pemeliharaan Listrik Rendah Dan Menengah

DESKRIPSI

Tulang punggung banyak sistem tenaga listrik adalah sistem distribusi tegangan menengah. Biasanya beroperasi pada voltase mulai dari 2.400 hingga 34.500Volt, tegangan voltase, korona, lonjakan, dan perlindungan peralatan, semuanya menciptakan tantangan unik dalam desain, pemilihan peralatan pengoperasian, dan teknik. Kelas 2 hari ini akan membawa Anda mempelajari dasar-dasar sistem tenaga tegangan menengah termasuk komponen, peralatan desain dan masalah pengoperasian serta perlindungan sistem tegangan menengah. Menimbang cukup kompleknya materi pelatihan Electrical Maintenance Low and Medium Voltage: TroubleShooting ini bagi peserta, dibutuhkan training provide yang berpengalaman di bidangnya agar tidak membua peserta tidak menjadi cepat bosan dan jenuh dalam mendalami bidang teknik ini.
