Dalam sistem tenaga listrik terdapat bagian yang saling terhubung bagiannya, menghasilkan energi listrik yang dapat disalurkan kepada konsumen dengan kualitas baik. SPSS (Statistical Package for the Social Sciences) program komputer dengan kegunaan sebagai analisis data statistika. Analisis korelasi merupakan salah satu teknik analisis untuk mengetahui kuat dan lemahnya hubungan antara dua variabel. Berdasarkan hasil analisis data menggunakan dasar keputusan analisis korelasi bivariate pearson, dapat dilihat faktor penyebab gangguan dan akibat gangguan dominasi pada jaringan transmisi Saluran Udara Tegangan Tinggi (SUTT). Berdasarkan hasil SPSS didapat hasil nilai kuat hubungan korelasi, akibat durasi pemadaman adalah instalasi peralatan sebesar 0,931, penyulang transmisi sebesar 0,308 dan cuaca sebesar 0,277 dan energi yang tidak tersalurkan adalah penyulang transmisi sebesar 0,143 lingkungan sebesar 0,118 dan instalasi listrik sebesar 0,096. Untuk melihat hasil kinerja jaringan transmisi Kalimantan Barat digunakan penilaian berdasarkan TLOD (Transmission Line Outage Duration) dan TLOF (Transmission Line Outage Frequency), maka didapat TLOD durasi pemadaman sebesar 0,420 jam/kms dan TLOF jumlah kali gangguan sebesar 2,31 kali/kms. PT PLN (Persero) UP3B Sistem Kalimantan Barat telah menetapkan nilai indeks TLOD yang sebesar 0,54 pertahun dan nilai indeks TLOF sebesar 2,87 pertahun, berdasarkan hasil tersebut dapat dikatakan nilai indeks masih dalam target kinerja saluran transmisi yang ditetapkan perusahaan.

In an electric power system there are parts that are interconnected, producing electrical energy that can be distributed to consumers with good quality. SPSS (Statistical Package for the Social Sciences) computer program with use as statistical data analysis. Correlation analysis is one of the analytical techniques to determine the strength and weakness of the relationship between two variables. Based on the results of data analysis using the decision basis of Pearson bivariate correlation analysis, it can be seen that the factors causing the disturbance and the effect of dominance disturbance on the High Voltage Air Line (SUTT) transmission network can be seen. Based on the results of SPSS, the results obtained are strong correlation values, due to the duration of the blackout, the equipment installation is 0.931, transmission feeder is 0.308 and weather is 0.277 and the energy that is not channeled is transmission feeder at 0.143, environment at 0.118 and electrical installation at 0.096. To see the results of the transmission network performance in West Borneo’, an assessment based on TLOD (Transmission Line Outage Duration) and TLOF (Transmission Line Outage Frequency) was used, so that the TLOD of the blackout duration was 0.420 hours/kms and the TLOF was 2.31 times/kms. PT PLN (Persero) UP3B West Borneo System has set a TLOD index value of 0.54 per year and a TLOF index value of 2.87 per year, based on these results it can be said that the index value is still within the transmission line performance target set by the company.
