Abstract

Pembangunan di Indonesia telah mengalami perkembangan pesat dan telah menyebar ke sejumlah kota besar ditandai dengan banyaknya gedung bertingkat yang dibangun. Pembangunan semacam ini melibatkan peran serta ahli perancang arsitektur, teknik sipil, mekanik, dan kelistrikan dalam perencanaannya. Salah satu tantangan awal dalam perencanaan sistem distribusi tenaga listrik di gedung bertingkat adalah merancang diagram satu garis rancangan sistem distribusi tenaga listrik di sebuah gedung hotel dan resort di Bali. Perhitungan nilai proteksi secara teknis dengan metode tabel atau tanpa tabel menjadi salah satu pertanyaan. Dalam penelitian ini dibahas tentang cara perancangan diagram satu garis sistem distribusi kelistrikan, khususnya untuk gedung bertingkat tipe highrises building dengan 5 hingga 10 lantai, dengan pasokan daya PLN 20 kV sebagai acuan pokok pada kontraktor dalam pemasangan instalasi listrik di lapangan. Perhitungan dimulai dengan menghitung beban dari gardu induk hingga titik ujung pada bangunan, termasuk perhitungan suplai tenaga darurat dari genset. Komponen sistem tenaga listrik pada gedung diuraikan, dan panel listrik dijelaskan secara garis besar. Daya total pada hotel ini adalah 744,2 kW, maka daya terpasang dibagi faktor daya (0,85) menjadi sebesar 93.025 kVA. Dan dengan permintaan daya sambungan ke PLN untuk jaringan distribusi tegangan menengah 20 kV dengan kapasitas 555 kVA, 3 fasa, 50 Hz. Besaran kapasitas Trafo dan Genset yang digunakan adalah masing-masing 315 kVA. Besar KHA pada kabel power panel lantai sebesar 192,8 A maka digunakan penghantar jenis NYY 4 x 120 mm2 + BCC 70 mm2 dan MCCB 400-1000 A. Besaran kapasitor bank dengan memperhitungkan arus (I) dan tegangan (V) pada diagram satu garis instalasi listrik maka akan menggunakan kapasitor bank sebesar 100 kVAr untuk mendapatkan faktor daya atau Cos Phi dengan nilai 0,85.

Abstract

The failure of electrical components in the industry can cause production process disruptions, and even accidents. Infrared thermography is an effective method for predictive maintenance, aiming to identify potential component damage before failure occurs. This research aims to analyze the condition of a 575 kVAr capacitor bank installation using infrared thermography. The standard used is the Standard for Infrared Inspection of Electrical Systems and Rotating Equipment. The results of the study indicate that the majority of the 575 kVAr capacitor bank installation conditions fall under priority scale 3, with a maximum temperature of 44.5°C and a delta T of 18.3, which means corrective actions need to be taken with scheduling permission. Corrective actions that can be taken include inspecting cable installations, tightening cable lugs, and tightening terminal connections on contactors and MCCBs. One part that has a priority scale 4 is the MCCB and contactor of the capacitor bank on the lower front section, with a hot point value of 35.1°C and a delta T of 8.9.

Abstract

Electric energy is important in human life, because almost all activities use electronic devices. Kiosks also have use of electrical energy. Small kiosks that can move around are not suitable for kWh meters (Grid). The solution is to utilize alternative energy in the form of Solar Power Plant, an independent energy producer by converting sunray into electric energy. Before system is built, planning is needed to get a reliable system. Method used to plan this system is R&D (Research & Development). The process includes: relevant studies, site(location) selection, load and energy consumption estimation, system design, component rating calculation, selection of components, design revisions, compiling budget plan, as well as conducting economic calculations. Planning results for a system with a load of 260 Watts and daily energy consumption of 1.1 kWh, system require 3 PV panels of 350 Wp, SCC rating 96V 60A max input with max power of 1440Watt at 24V, inverter 24/220V 50Hz with 1000Watt continuous and 2000Watt maximum power, battery bank with capacity of 300Ah 24V. System is feasible and profitable because it has a payback period (PP) value < PV panel lifetime, as well as an RoI (Return on Investment) percentage value of +11% profit.
