Abstract

Saluran EHV (Extra High Voltage) yang panjang seringkali dilengkapi dengan Shunt Reactor untuk mengompensasi saluran daya reaktif kapasitif dan menekan tegangan berlebih. Biasanya reaktor dipasang diantara titik netral reaktor fase dan tanah untuk mengompensasi kapasitansi kopling antar fase. Reaktor netral ini bisa mengurangi amplitudo arus busur sekunder yang akan mengurangi waktu kepunahan busur sekunder saat penutupan saluran transmisi.
Hasil yang didapat dari simulasi ini gangguan satu fasa ke tanah Secondary arc mengalami penurunan dari 591,15024 A menjadi 401,982 A Setelah dipasang Shunt Reactor dan reaktor netral, lalu pada gangguan dua fasa ke tanah Secondary arc sebelum dipasang adalah fasa R = 338,64 A dan fasa S = 363,515 A menjadi fasa R = 243,821 A dan fasa S = 247,19 A setelah dipasang Shunt Reactor dan reaktor netral, Pada gangguan tiga fasa ke tanah Secondary arc sebelum dipasang adalah fasa R = 83,3861 A, fasa S = 386,564 A dan fasa T = 315,249 A menurun hingga fasa R = 56,7025344 A, fasa S = 26,863302 A, dan fasa T = 214,3694016 A setelah dipasang Shunt Reactor dan reakor netral.
===============================================================================================
Long EHV (Extra High Voltage) lines are often equipped with shunt reactor to compensate for capacitive reactive power lines and suppress overvoltage. Usually the reactor installed between the neutral point of the phase reactor and the ground to compensate the interphase coupling capacitance. This neutral reactor can reduce the secondary arc current amplitude which will reduce the time of secondary arc extinction when the transmission line is closed.
The results obtained from this simulation of single-phase to the ground faults of the secondary arc decreased from 591.15024 A to 401.982 A. After the shunt reactor and neutral reactor were installed. Then the two phase to ground faults the secondary arc before it is installed is the phase of R = 338.64 A and phase S = 363.515 A into phase R = 243.821 A and phase S = 247.19 A . after installing the shunt reactor and neutral reactor. The three-phase to ground faults secondary arc before being installed are phase R = 83.3861 A, Phase S = 386.564 A and phase T = 315.249 A, decreased to phase R = 56.7025344 A, S = 262.863302 phase A and phase T = 214.3694016 A after the shunt reactor and neutral reactor were installed.
