Re: Kapan breaker LSIG digunakan?

The letters LSIG signify the type of protection and available adjustments on certain trip units.

  • L = Long Time (overload protection, analygous to the inverse-time thermal trip of a thermal/magnetic breaker)
  • S = Short Time (short circuit protection of low level faults)
  • I = Instantaneous (short current protection of high level faults, analagous to the instantaneous magnetic trip of a thermal/magnetic breaker)
  • G = Ground Fault (equipment ground fault protection)

LSIG = Long-time + Short-time + Instantaneous + Equipment Ground-fault Protection.

 

Pak @Dwinanto_Setyadi @HendySE @sesa23155 jika ada yang mau ditambahkan.

Re: Kapan breaker LSIG digunakan?

Hi, guys.
Are Inverse time circuit breakers also known as thermal-magnetic circuit breakers?

Re: Kapan breaker LSIG digunakan?

Breaker dengan LSIG protection digunakan untuk aplikasi dengan kebutuhan diskriminasi total sistem proteksi antar breaker terkait proteksi overload dan short circuit. Sedangkan proteksi arus gangguan tanah menggunakan metode residual netral protection. proteksi arus gangguan tanah ini digunakan untuk proteksi dari potensi kejadian short circuit phase ke ground atau ketidaksetimbangan sistem phase yang mengakibatkan arus mengalir di konduktor netral

 

Breaker dengan LSIG protection aplikasinya banyak digunakan di panel utama di breaker incoming dimana mendekati sistem penyulang utama. koordinasi proteksi dengan breaker dibawahnya dengan metode diskriminasi 

 

Semoga membantu
