Penggunaan Sectionalizer untuk Proteksi Gangguan Arus Lebih pada Jaringan Distribusi 20 KV

Abstract

Development of our electricity is nowadays more progressive as increasingly requirement of the electricity. In a power system, there are many channels of distribution such as radial, loop, gnd and spindle systems. And the increased channels of distribution, the possible default also tcnds to incrsase. For that reason, in distribution of electrical power, continuity of service should be taken into account. To keep the distribution of electricity remain reliable, the operation of such systems should be maintained from any possible defaults. It should be considered due to it relates directly to the loading center of such a distribution To avoid the occurrence of power defaults, some protective devices are required in which the tools have capability to separate the default channel and if the default is temporarily or permanent, the tool used is sectionalizer. It functions to break a load automatically can separate the default sections from a distribution system or it can localizer the defaults in a section by which the undefault sections remain receives electric power. In fact, the use of sectionalizer is one of the best methods to be implemented in a distribution channel with an open airway because of if is forced to shutoff or termination of electric power service, the use of such a sectionalizer is only on the default section.
