Kode angka dalam sistem kelistrikan oleh Mas Bejo · Mei 21, 2013

Kode angka dalam sistem kelistrikan Dalam single-line diagram (diagram garis tunggal) suatu sistem instalasi, maka akan kita jumpai kode-kode angka pada keterangan gambarnya, hal ini dimaksudkan untuk mempermudah kita dalam membuat penamaan suatu peralatan. Adalah ANSI (American National Standards Institute) yang membuat standarisasi kode angka tersebut. Kode angka yang tertera, kadang ditambahkan juga dengan huruf alphabet yang akan memberikan keterangan tambahan, sebagai contoh kode 51G yang berarti untuk OverCurrent Ground Relay, lalu 50N yang mengindikasikan alat Ground Sensitive OverCurrent Relay dengan rujukan pembacaan arus Netralnya, dan ada juga 87T yang artinya untuk peralatan Differential Relay yang digunakan pada Transformator. Berikut daftar kode angka dalam sistem kelistrikan : 1.
