Abstract :
In meeting the needs of electricity, there is a disruption of current in the SUTM network system at PT. PLN (Persero) UP3 Cengkareng thus inhibiting the power supply line in the form of disruption currents. As a result of the current disruption it is necessary to handle the installation of Recloser as interference current protection. Recloser is an automatic electrical circuit breaker. This equipment can work when there is a interference current it will order the operation to open and close to the power circuit breaker automatically according to the time set. This study aims to analyze the installation of Recloser as a protection for short circuit fault currents in Kaze feeders at PT. PLN (Persero) UP3 Cengkareng. The method used in this research is to calculate the short circuit fault current and its Recloser setting. The calculation results show that the three phase disturbances at kilometer 0 are the maximum interference current of 12396 ? -90 ° A, while the disruption of three phases at kilometer 7 is a minimum interference current of 3224 ? -65 ° A. In kaze feeder, Recloser hatching is located at km 5.2. Short circuit interference current 3 phase located at kilometer 5.2 which is 4014 Ampere. Recloser setting value of 0.44 ampere with TMS setting (Time Multiplier Setting) Standart Inverse and in can Recloser time work after an interval of 0.30 seconds.
