Abstract

Protection systems have a significant role in maintaining the stability and reliability of the electric power systems. Usually, protection systems are designed with a purpose which is protecting given equipment on the power systems without compromising the integrity of the system. In protection systems, there are several problems that always occurs which is blinding, false tripping, high-set instantaneous and loss off coordination. Normally, these problems cause a lot of damage and affect the electrical system. False tripping event usually occur due to voltage dips or sag that result from the external short circuit that occur in the electrical power systems. The voltage dips spread through the electrical system even at the equipments which are not on the path of current. The objective of this research is to identify problems that cause false tripping event while identify the factor that affecting the power quality. This paper will focus on false tripping event and will discuss various reasons that contributed to false tripping event.
