Abstract

To obtain a small earth (near zero) resistivity value is determined by the number of planted electrodes and soil type properties. Difficulty in obtaining this small resistivity value often errors in estimating soil properties or soil type resistance so that failure to obtain soil barriers often occurs.To determine the desired amount of material can be measured soil type resistor value, by measuring the soil resistivity value so that the estimated material cost estimation can be achieved well. then in this research using geoelectric method with Schlumberger configuration. Schlumberger method is a method with a constant system of spacing rules with the note of the 'n' multiplier is the comparison of the distance between the C1-P1 or (C2-P2) electrodes with P1-P2. The instrument used is a resistivity meter ( Naniura) equipped with four electrodes which have the ability to read output voltage response due to current injected into the ground surface through two current electrodes and two potential electrodes. In this study used progress to map the 2D isoresistivity beneath the measured surface. .The results of this soil resistivity measurement can be determined with certainty the amount of material used and the cost of workmanship provided to establish the proper grounding system to be attached to a 20 kV Distribution substation at the State Polytechnic Padang State Electricity Laboratory. So that the grounding system in pairs meet the standards that have been determined and can be categorized both and safe for humans and equipment for grounding Distribution Distributors 20 kV Electricity Engineering Laboratory at the State Polytechnic Campus Padang

Abstract

Dengan melakukan reconnecting dapat mengatasi rugi-rugi energi. Pada titik sambungan percabangan disambungan rumah sampai ke kWh meter digantikan dengan compression Connector. Terminal pada kWh meter sering terjadi loss kontak. Dengan sering terjadinya loss kontak, maka terminal pada kWh meter digantikan dengan menggunakan joint sleeve bimetal. Besarnya rugi jaringan disebabkan oleh penggunaan tap connector pada titik sambungan dan terminal pada kWh meter pelanggan. Digardu 079 Sovia area kerja PT. PLN (Persero) rayon Bukittinggi mengalami rugi kWh salur pada bulan desember 2013-januari 2014 sebesar 13 %. Setelah dilakukan reconnecting, rugi kWh salur menurun menjadi 4,48% pada bulan Mei 2014. Dengan menggunakan jaringan Syaraf Tiruan, dapat dilihat kinerja untuk rugi kWh salur setelah dilakukan reconnecting lebih baik.

Abstract

Lambung Bukit Batu Busuk, Pauh, located in Padang City, West Sumatera established a prayer room which was named Mushalla Al-Barkah. This mushalla is used as a place of worship for muslims around Lambung Bukit Batu Busuk Padang. Some of the the worship activities carried out at the mushalla, include congregational prayer activities, Al-Qur’an education and other worship activities. These activities really need electricity in their implementation. The mushalla need loudspeakers to adzan, the mushalla needs lights for lighting at night. However, the incomplete installasyion of electrical installations in the mushalla has resulted in delays in worship activities in the mushalla for the community around Lambung Bukit Batu Busuk, Padang. Because of that the community implementation team carried out the development of lighting installastions and elekctric power installasions at Mushalla Al-Barkah. After this activitiy was complete at the mushalla, the mushalla’s electrical installation was perfect. This activity is useful for partners and can be used as a promotional agenda for the people Lambung Bukit, Pauh to get to know the Padang State Polytechnic.

Abstract

The large use of power converters in distribution lines causes poor power quality such as high produces harmonics in an electric power system that arises due to the operation of non-linear electrical equipment. The presence of harmonics in the power system distribution results in a very large loss in the system. In this paper had been done a simulation of power quality improvement through harmonic reduction using parallel active power filter. Active power filters work with control techniques based on the concept of instantaneous power to determine the amount of compensation currents that must be generated by the power compensator power circuit. The compensating current references generated by the control circuit are used by the hysteresis type controller to provide harmonic compensation arising. From the result of simulation using Simulink MATLAB, the harmonic value (THD) decrease caused by the 3 phase rectifier load on a distribution network which is used as case example. The harmonic value before compensated on the network is 27.85% at each phase, while after computing the harmonic value of the network decreases to 1,43% in R phase, 1,49% in S phase, and 1,34% in T phase.
