Abstract

Failure of Insulators of ‘Line Post Insulator 70 kV type’ usually caused by many factors, such as the leakage current on contaminated insulator surfaces. This leakage current will cause interference with the electrical energy distribution system. This study reported the results of testing the leakage current on insulator 70 kV Line Post Insulator type  performed on high-voltage laboratory Ujung Pandang State Polytecchnics. Based on testing, the maximum leakage current value obtained in wet conditions polluted with spraying of pollutants ESDD = 3.2 mg/cm2 and NSDD =  0.08 mg/cm2 with a value of leakage current of 7.4 mA at an applied voltage of 22 kV, this can result in flashover.

Abstract

Determination of the minimum spanning tree are widely used to solve optimization problems of finding solutions to problems that require minmum. In the electricity distribution network, minimum spanning tree (MST) is used to find the minimum length of cable for electricity network system becomes more optimal. Minimum weight of a MST primary distribution power network is strongly influenced by the geographical conditions of a region in the form of contour data. Contour data is spatial data that contains information of the earth surface elevation of an area. To determine the primary distribution grid MST needed an algorithm that can produce optimal solutions. In this research the algorithm used is algorithm Prim. Prim's algorithm is an algorithm in graph theory to find the MST of a weighted graph with emphasis on the selection of minimum weight based on the node is taken. This research was done by designing a model of primary distribution power network graph in accordance with the data obtained. In finding the minimum weight for each side of the network graph should include parameters elevation, high point / node, and the distance between points / nodes. Furthermore, the graph is done by computer calculation and simulation to get the electricity distribution network primary MST using Prim's algorithm with the help of ArcView GIS 3.3 program through the avenue script. Prim's algorithm included in the category of good or efficient algorithms, because the shape of polynomial time complexity in n, where n is a measure of the number of vertices or sides. Based on the test results have shown that the algorithm Prim MST ability to determine the primary distribution grid is much better if based on the geographical conditions of a region. In addition, Prim's algorithm graph computation time in generating the MST based on the data that is not based on the contour and contour data are quadratic. Keywords: minimum spanningtree, prim'salgorithm, contours, complexitytime, distribution  electrical network, graph.

Abstract

In electrical engineering technology, especially information technology today can be applied to all areas of life. In this rapid technological developments, information technology can be utilized as a means of information for the primary electrical distribution channels in the form of a geographic information system making it easier for users of the system to determine the condition of the electrical distribution channel. This study uses a program that comes with ArcView avenue script programming to implement a geographic information system primary electrical distribution channels in the city of Palu using digital maps. Geographic information system designed and fabricated in this study proved capable of displaying all the information on the primary electrical distribution channels in which the data taken from the PT. PLN (Persero) ray on branch of Palu city. Keywords:Geographic Information Systems, Digital Map

Abstract

The problem of the society when it will require new electrical connection  to PLN especially household bill level is  the ignorance on the procedure and costwhich have to be paid so that it asks helping to the brokers. This paper describes about how to calculate cost of new connection installing which must be paid to PLN based on Kepmen ESDM No : 07 Tahun 2010,  cost of electrical installation based on the amount of the power required, and how to calculate cost of usage based on new base rate2010. Key words: electric base rate, new connection cost, installer cost

Abstract

The study aims to design decision support system using triangular fuzzy number approach in Analytic Hierarchy Process method. The Analytic Hierarchy Process (AHP) is one of the decision support system method which controls experiences and intuition but critical at coupled comparative scales because it uses crisp. A triangular fuzzy number is used to approach AHP scale so as to obtain more fexible value of coupled comparison. The triangular fuzzy number-AHP method uses analysis synthetic extent in the priority processing implemented on ranking cases of potential acceptors of scholarship of PPA and BBM in Technic Faculty Tadulako University of Palu. The result is the average of mismatch between the result by triangular fuzzy number-AHP method and the result of manual work which are 23.93% of the PPA scholarship and 27,35% of the BBM scholarship.   Keyword :Triangular Fuzzy Number, Analytic Hierarchy Process, scholarship

Abstract

Harmonic is one of sinusoidal components, one wave period from which having multiple frequency of its fundamental frequency one, leading to electrical power quality problems. Harmonic distortion in term of voltage and current ones, generally is due to non linier impedance. Inverter is one of example of it. There are some items that will be measured. There are value of harmonic at  source and value of voltage and current harmonic when inverter does not have any load. IEEE Standard of 519-1992 as a reference in determining maximum limitation voltage and current harmonics. The result of the tests were showed that voltage harmonic distortion at inverter did not exceed the IEEE 519-1992 maximum limitation of 5%. While current harmonic distortion had exceed the maximum limitation of the IEEE 519-1992. The highest results were exceeding 57,52 % when inverter does not have any load. After using passive filter that function for reducing the value of harmonic,  the total harmonic distortion (THD) current w only 6,837%  when inverter does not have any load.   Keywords : Voltage, Current, Harmonic Distortion, Passive Filter.

Abstract

The development of science and technology, especially information technology, internet use in education continues to grow. Use of the Internet is not just for distance education, but also developed in the conventional education system. E-learning is a learning model that is created in digital format through an electronic device. Purpose of the use of e-learning in the learning system is to expand access to education public, so that learning modules can be accessed easily, without diabatasi space and time, interactive, and effective. In this paper a prototype using a software development methodology that emphasizes the approach to aspects of design, functionality and user-interface. The final product is expected to be a module-based learning application of information technology. Key words: Internet, the quality of education, information technology, e-learning
