Abstract

Presidential Instruction recently about saving and energt efficiency, it is necessary that efforts should be made to support the program. In energy savings in the household sector can be done in various wavs from the smallest thing turning off lights that are not necessary to the utilization of waste heatfrom air conditioning to hot water purposes. Alternative technologies, the heat energy generated by the air conditioning unit is the potential energy that can be utilized to get hot water for free. Given theclimate in Indonesia is quite hot, many hospitals, hotels, residential upper middle or apartment is equipped with air-conditioning and heat generated in the cooling system is disposed into the environment. Infact. the heat energy can be used for heating water can be usedf or water bath or otherpurposes. It is necessary to develop a means of combined cooling and heating water. These devices are expected simultaneously to increase comfort and save energy.Keywords: Conservation of energy in refrigeration I pk

Abstract

ABSTRACT This combination; Automatic mass and high measurement device based on microcontroller ATMega 8535, is a combination which can measure for high and mass digitally. This combination consist of some blocks, power supply 5V and there are 2 censors; ultrasonic and optocoupler which is an input of this device, and microcontroller ATMega 8535 is as a program controller and LCD is as presenter. Censor ultrasonic HSCR-04 will detect things surrounding censor, censor radiator will send ultrasonic phase. If ultrasonic phase bounches back to the receiver, it means there is an object surroundings censor and optocoupler censor will count the hole in analog weights. Then, the second result is sent to microcontroller to be calculated to LCD to be shown. Keywords : Keywords: ultrasonic censor, optocoupler, Microcontroller ATMega 8535, LCD

Abstract

Distribution of electricity to consumers through some process that begins from power plants to substations supplied (sub-station), then lowered into the substation -a low-voltage distribution substations. The distance is too far between the point on the voltage distribution in particular between the IBT to the parent distribution substation secondary voltage drop triggers, It is as well as on the distance between new or IBT IBT cilegon Gandul to trigger serpong substation secondary voltage drop at substation serpong.To stabilize the voltage of the secondary to the primary voltage on distribution transformer tap changer operation. Problems arise when the tap changer to operate too much will lead to the over-excitation of the distribution transformer. The side effects of the over-excitation also trigger an increase in temperature of the thermal transformer, so the effect on the components within it, is no exception to the isolation of paper inthe process of thermal temperature rise is accelerating aging insulating paper it self. The exixtence of aging insulating paper must be accompanied by the estimated number of clear that the replacement of aging insulating paper on time, so it requires the calculation of accurate data on the thermal temperature kenaiakan to aging transformer paper insulation.Keywords: electricity distribution process, reduced secondary voltage, over-excitation, aging insulating paper, the estimated value.

Abstract

Insulation materials that commonly used in air insulation, which, is operated at high voltage, are the porcelain, glass, and polymer materials. One of the insulating polymer materials that are used is epoxy resin because it has several advantages compared to that. However, this insulation material has a degradation of the surface due to environmental and cause insulation coated with dirt and chemicals in the long time. Material that was used in this research was epoxy resin polymer isolation using of comparison values (base material diglycidyl ether of bisphenol-A: hardener material metaphenylene diamine) were 1:1, with the increase of silane and high calcium coastal sand as filler by the value of 10%, 20%, 30%, 40%, and 50%.Research was done in laboratory according to standard IEC 587: 1984. In this study, the effect of variation in stoichiometry to the hydrophobic contact angle value, leakage current waveforms, and surface degradation caused by erosion and tracking processes and tracking time were analyzed.From the results of the research, it was obtained that the epoxy resin that was used in this research are categorized as hydrofobik and partially wetted. The increase concentration of silane dan Kukup coastal sand as filler caused the increase in contact angle which meant the increase in surface insulation resistance, so that leakage currents flew on the surface not easily and slow down the aging or the degradation decreasing on the surface of insulating material. Concentration value of filler that had the optimal performance of the tracking process and erosion was 40%.Keywords : angle of contact, epoxy resin, hidropobik, isolator, leaky current, materials filler

Abstract

Lately, the problem of hot point on substation equipment in PLN be an interesting thing to say. Mainly about heat problem which is uncontrolled and unable to be checked continually, this issue deals with the system’s safety and reliability that happens in the substation To overcome this issue, study on the solution which is by making a prototype device to measure real time temperature or hot point continually and by using wireless has been held. This device uses ATMEGA 8535 and heat sensor TPA 81 then it sends the data bay FM signal and later on, this data can be shown and save in computer Using the prototype, the problem that PLN faces these days can be solved, because this prototype device can monitor the hot point change continually and real time
