Apakah aman untuk mempunyai waktu interval (CTI) 100 ms untuk dua relai?

Halo, mau tanya, end user saya meminta spesifikasi interval waktu koordinasi antara dua relai menjadi 100 ms, karena adanya beberapa relai dan breaker yang fast tripping. Sedangkan menurut IEEE 242, interval koordinasi minimum membutuhkan 0,12 detik antar relai, tanpa memperhitungkan open time breaker.

 

Yang ingin saya tanyakan, apakah aman untuk mempunyai waktu interval (CTI) 100 ms atau ada informasi dari guideline lain?

Terima kasih

Hi @Anonymous user ,

 

Kalkulasi setting koordinasi relay yang tepat dan aman hanya dapat dilakukan dengan Power System Study, misalkan menggunakan software ETAP.

Belum tentu satu nilai setting bisa diterapkan pada sistem jaringan yang berbeda.

 

Untuk lebih memahami sistem proteksi, Anda bisa mendapat ebook Network Porotection and Automation Guide secara gratis pada link berikut:

Terima kasih.

Hi @Fikri_Ferdiana ,

 

Terima kasih atas informasinya Pak! Ebooknya akan coba saya pelajari.

Untuk software ETAP, apakah ada trialnya yang bisa kami coba?

 

Terima kasih.
