“…Sistem tenaga listrik bersumber dari pembagkit yang terdri dari PLTU (pembangkit Listrik Tenaga Uap), PLTA (pembangkit Listrik Tenaga air) dan PLTB (Pembangkit Listrik Tenaga Bayu), [1][2][3] bertempat jauh dari pusat-pusat beban sehingga diperlukan jaringan transmisi dan distribusi untuk menghubungkan. Terdapat peralatan lain untuk mendukung menyalurkan daya listrik tersebut yaitu transformator yang merupakan alat yang berfungsi untuk menaikan dan menurunkan tegangan.…”

Transformator merupakan unsur utama dan merupakan mata rantai terpenting dalam penyaluran dan distribusi tenaga listrik. Sehingga diperlukan sistem proteksi yang selektif, andal, sensitif, dan cepat untuk menjaga keandalan trafo. Salah satu komponen proteksi trafo adalah CT (trafo arus) yang berfungsi sebagai pembaca arus proteksi relay, apabila terjadi gangguan maka relay proteksi mendeteksi adanya keabnormalan sehingga memberikan sinyal trip pada PMT untuk memutus rangkaian listrik. Relay pada sistem proteksi trafo memiliki lokasi pengamanan yang berbeda. Di PT. PLN (Persero) UPT Cirebon, terjadi gangguan pada bay trafo yang mengakibatkan relay bekerja. Namun kerja relay ini tidak sesuai dengan lokasi gangguan yang terjadi. Setelah diinvestigasi didapatkan bahwa CT pada bay trafo memiliki desain peletakan yang kurang tepat sehingga mengakibatkan salah kerja relay (kurang selektif). Untuk memperbaiki kesalahan tersebut, maka dilakukan perubahan wiring CT pada trafo produksi lama. Perubahan wiring CT ini disesuaikan dengan ketentuan SPLN T5.003-2010 Tentang Standar Pola Proteksi Transformator Tenaga sehingga apabila terjadi gangguan relay bekerja sesuai dengan lokasi proteksinya. Hal ini terbukti pada saat terjadi gangguan setelah dilakukan perubahan wiring relay bekerja sesusai dengan fungsinya, sehingga prinsip sistem proteksi terpenuhi, yaitu selektif, andal, sensitif dan cepat.

“…To reduce this disturbance, efforts are being made to use parallel inductance using a NA2XSY cable which has a lower inductance than the tower, which is 0.461 H/m, so that when paralleled with the tower, the inductance becomes 0.315 H/m. If the inductance is small, the voltage that arises due to a lightning strike will also be smaller so that there is no backflash over [11][12][13][14][15][16].…”

SUTT 70 kV Parakan-Kadipaten is one of the transmission networks located in areas with high lightning activity so that there is the potential for interference. If the voltage (V) caused by lightning > Basic Insulation Level (BIL) insulator, a backflash over will occur. One of the efforts made to minimize interference is by paralleling the tower inductance with NA2XSY cable which has a lower inductance than the tower. This study aims to determine the installation method and the effect of parallel installation of inductance to reduce interference due to lightning strikes. The research was carried out by performing calculations to determine the lightning Vimpuls before and after the parallel inductance and then comparing it with the BIL value of the insulator and network disturbance data. If the lightning Vimpuls > BIL insulator then a backflash over occurs and if the lightning Vimpuls < BIL insulator then there is no backflash over. From the calculation results, it is found that the value of lightning Vimpuls before parallel inductance > BIL insulator and after parallel inductance drops significantly to < BIL insulator. Meanwhile, when compared with the fault data 3 years before and 3 years after parallel, the fault inductance also decreased. In the year before the parallel inductance, namely 2015 there were 4 disturbances, in 2016 4 disturbances, in 2017 1 disturbance, and in 2018 the January-June period there were no disturbances. In the year after the parallel inductance installation, namely in 2018 for the July-December period there were no disturbances, in 2019 there were no disturbances, in 2020 there were 2 disturbances, and in 2021 the period (January-June) had 2 disturbances.
