Abstract

KINERJA BATERE (BTD03) DAN INVERTER PADA SISTEM CATU DAYA TAK PUTUS 220 V-AC (BTP03) RSG – GA SIWABESSY. Batere merupakan salah satu sumber catu daya yang banyak digunakan untuk cadangan energi bila terjadi kegagalan pada catu daya utama. Batere yang digunakan sebagai Uninteruptible Power Supply (UPS-AC)/catu daya tak putus di RSG GAS terdiri dari 2 sistem, yaitu 2 (dua) buah UPS masing-masing 220 V-AC (BTP01 dan BTP03). Batere BTD03 telah mengalami pergantian 2(dua) kali, pergantian terakhir dilakukan karena adanya tegangan lebih saat charging, yaitu 268 Volt, sehingga jumlah batere yang semula 111 buah ditambah 9 buah menjadi 120 batere dengan total tegangan 240 Volt. Pengukuran tegangan dan arus dilakukan pada keluaran inverter (BTP03) dan pada keluaran total batere saat catu daya diperoleh dari batere (proses discharge). Tegangan keluaran inverter pada masing-masing phasa masih memenuhi syarat, yaitu V1 = 221 Volt, V2 = 223 Volt, dan V3 = 226 Volt . Perbedaan yang tinggi antara V3 dengan standar tegangan 220 V, yaitu 2,65% masih memenuhi syarat PUIL 2000 yang mensyaratkan variasi tegangan yang diijinkan +5% dan -10%, sedang menurut ANSI C 84.1 adalah +4% dan -10% danarus rata-rata beban I1 = 11,8 A, I2 = 5,82 A, dan I3 = 5,81 A. Tegangan dan arus DC batere selama discharge 7 jam diperoleh V = 213 Volt dan I = 17,3 A, dimana saat tegangan 213 Volt atau tegangan per cell batere 1,775 Volt terjadi alarm under voltagedan ini menunjukkan sistem UPS BTP03 masih berfungsi baik dan batere BTD03 terlindungi.

Batteries are one source of power supply that is widely used for energy reserves in the event of a failure in the main power supply. Batteries are used as Uninteruptible Power Supply (UPS) in RSG GAS consists of two systems UPS 220 V-AC, namelyBTP01 and BTP03.Battery BTD03 has already changed2 times, the last was changed due to over voltage during charged, i.e 268 Volt, so that the amount of battery which previously 111 pieces add with 9 batteries to 120 pieces of batteries with a total voltage of 240 Volt.Voltage and current measurements carried out at the inverter output (BTP03) and the total output of the battery when the power supply is obtained from the battery. Load voltage at each phase are still qualify, i.e V1 = 221 volt, V2 = 223 Volt, 226 Volt and V3 =226 volt.The difference between V3 with a standard voltage of 220 V is 2.65%, which is still qualify of PUIL 2000 which requires allowable voltage variation + 5% and -10%, while according to ANSI C 84.1 is + 4% and -10%, and the average current I1 = 11.8 A, I2 = 5.82 A, and I3 = 5.81 A.DC battery voltage and current during 7 hours discharge are V = 213 volts and I = 17.3 A, in which the voltage of 213 volts or per cell of 1.775 Volt, under-voltage alarm occurs and this shows UPS system (BTP03) is still functioning and battery BTD03 is protected.
