Abstract

The aim of this study was to find an information about varying soil resistant along residence area in Bantul Regency. The aim of the study is to compiling fixed grounding system. Factors controlling the grounding are ground resistivity, electrode resistivity, environmental condition, size and shape of the system. Ground resistivity needs a good grounding system, that accomplish to savety standard for people and its equipments. The ground system should be able to prevent dangerous caused by flash, whenever nuisance come out. It parposes to overcoming the current of ground system nuisance of electricity power, in order the power could be flowing to the ground, directly; not to the equipments. The resistivity data resulted from the field work measurements, shows some different va-lues in each place, that probably caused by different kinds of soils. For examples are re-gusol soil has a resistivity value of 22.05Ω, latosol 17.04Ω, and red mediteran 15.12Ω. Grumusol soil has resistivity of 7.8Ω, but after it’s analyzed by grounding with 4 electrode, the value is decrease into 4.22Ω. Those are caused by grumusol soil is clayy, while the other soils are sandy. Based of IEEE recomendation of ground resistivity values, home electricity should be <10Ω, while for flash protection should be < 5Ω. Up to now, the solu-tion for quenching the overload power, in order it’s unable to damage the equipments, it’s flowed to the ground directly.

Abstract

The use of electrical energy is made as efficient as possible, therefore to get the economical value, especially in the use of Fluorescent lamps, it is necessary to make an effort how to use energy that approach the installed value. The effort was dane by in cir-cuit tests using fluorescent lamps with different capacitor values and comparing them with economical lamps. Having obtained the capacitor values, the experiment were carried out to collect the actual data of the installed power. The resuls of the experiments were analyzed and showed that the increasing values of capasitors were followed by better power factors so they approached the associated installed powers.

Abstract

In rural areas there is generally a major irrigation canal that serves to irrigate the fields and also has the potential to be used as power plants. Developments Wukirsari Imogiri Bantul area, an agricultural region and its inhabitants have a side job as grate the coconut and make various handicrafts for souvenirs that use raw materials from a particular timber. Development of today's technology provides a variety of environmental impacts, both positive and negative, in the presence of micro hydropower plant in one of the villages in the area Imogiri will certainly add a positive impact for local communities. In the presence of micro-hydro, if night can be used as a means of public street lighting so that security and a sense of anxiety at night reduced incomes and to increase trade group be established to process the materials of wood and iron to take advantage of wood-working equipment that require electricity results from the existing micro-hydro power, yet still very limited relative kapisitasnya. Side activity that utilizes peratan carpentry can not be fulfilled using electricity from existing plants.Therefore we need an increased effort on Micro Hydro Power (MHP) is still very limited relative power. So in this study, is expected to obtain an increase in power can be realized with both and can obtain results in line with expectations.

Abstract

Providers Backup Power Supply for Household Electricity Load In automatic, very necessary as an emergency response efforts in the event of termination of electricity to consumers. So with a backup power supply that has been prepared, the electric lighting in the household is not disrupted. The effort is meant is conducted by making a piece of equipment such as power supply 1 Phase Inverter System Design for Load Capacity 1200 Watt, is a piece of equipment that can serve as a replacement power supply but can work efficiently and save energy. After designing and testing tools execute the inverter, it can be some of the results of the designation gauges recorded and performed calculations. The larger the installed load will produce a greater flow, this caused huge load requires a large current flow. At 50-250 cosQ load close to 1, while the 300-1200Watt load cosQ up and down, this happens when the 300-1200Watt load test, the load used in the form of incandescent bulbs. The voltage on the inverter device is sometimes not reached 220 volts when tested. This is due to the voltage source when the test does not reach the stable, and also due to the greater load at the time of testing with mixed loads. Long period of time of an inverter is able to work depends on the quality of the battery and how to use it.

Abstract

The research was carried out to get information about the improvement of gro-unding resistant value in tower feet of-high-voltage network, 150 kV, along tower trans-mission in power station, Bantul, Semanu. A good grounding system is used to flow cur-rent into the ground and prevent the current flow into the electrical equipment if electrical fault occurs. The result of measurement has shown that ground, type grumosol has a low grounding resistant value <10 Ω because its ground texture of clay has high ability to absorb and keep water and has very tiny particles and colloid property. The grounding resistant values of type regusol, litusol, brown latosol and red mediteran are above 20 Ω because of their ground texture, sand and clay. Chemical and physical reaction will take places in soil with clay structure. Its colloid property can tie/hold ion or water and sometimes free salt. The aim of this research is to get information about resistant value of soil type with almost ≤ 5 Ω by installing grounding electrode made from four galvanis steel coated with bronze with 15 mm in diameter, 10 meter long and two ground rods are parallel connected with 2 m each electrode and use counterpoise grounding system model. The result of the improvement is expected to meet standard requirement, SPLN almost ≤ 5 Ω.
