Sistem Diferensial Arus Garis GE L90-A00-HCH-F8A-H6B-L6B-N6B-S6B-U6B-W7A

Deskripsi Produk

L90 memberikan perlindungan diferensial arus berkecepatan tinggi yang cocok untuk saluran transmisi dan kabel dengan berbagai tingkat tegangan, sekaligus mendukung perlindungan jarak lengkap dan aplikasi pemutus ganda yang cocok untuk aplikasi tripping tunggal dan tiga kutub. L90 menggunakan pengambilan sampel tersinkronisasi di setiap relai untuk membatasi dampak masalah saluran komunikasi. Pengekangan adaptif elemen diferensial menyeimbangkan sensitivitas terhadap kesalahan internal dan keamanan selama kesalahan eksternal. L90 mendukung komunikasi perlindungan antar-relai melalui serat langsung serta antarmuka yang berbeda.
