The only load that can be supplied is DC load because there isn’t installed inverter. Therefore, it is necessary to determine the inverter specifications to be installed in small-scale solar system. This research aims to determine the specifications and test the performance of a 500 W inverter integrated with a 50 Wp solar system. Also analyze power quality parameters and efficiency when connected to various load. The test method is no-load and load testing with the parameters measured including current, voltage, power, frequency and THD. Analysis was also carried out on the correlation between efficiency and loading and inverter pins with THDV and THDI. In the no-load test, the inverter output voltage waveform was obtained as a pure sine wave with a frequency of 50.10 Hz. In testing the LED and LHE loads, it was found that the inverter was good for use when the load was 50-80% of its capacity. The lowest THDV value is at a Pin value of 26 W, namely a THDV value of 0.009%. The highest THDV on the Pin is 130 W with THDV value of 1.9%. The lowest THDI value is at Pin 9.75 W, namely 27.6%. The highest THDI value on the 130 W Pin is 80.9%. The THD limit is still within the IEEE standard limit, namely 5% - 10%.","PeriodicalId":476257,"journal":{"name":"Elposys: Jurnal Sistem Kelistrikan","volume":"13 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140438566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The distribution network's primary function is to reduce high-voltage electricity, typically from 150 kV to 20 kV, while substations further lower it to a low voltage of 220 VAC for consumer use. However, over time, supporting equipment such as panels, cables, and transformers in the electrical network system can experience a decrease in quality, with a potential decline of up to 20% over 10 years. This degradation is due to various factors, necessitating the installation of protective measures and routine or annual maintenance to prevent potential risks. To maintain equipment quality, maintenance activities include cleaning, testing protection devices, and coordination between substations and workers. These measures are essential for the efficient operation and the successful distribution of electricity. This study evaluates the reliability of equipment at substation panel P50, with test results indicating insulation resistance values of 64,500 MΩ, 73,600 MΩ, and 87,100 MΩ, as well as a delta time of 0.7 ms.

So it is necessary to use energy as efficiently as possible. So there is a need for an energy audit to determine the level of electrical energy consumption used, where the results will be compared with predetermined standards. This research was carried out at CV Tirta Windu Agung 3 using a PM5100 and lux meter. From initial audit calculations, the IKE value was found to be 13.42 kWh/m2/year. This IKE value is the total of the buildings and ponds. The IKE value still includes very efficient criteria. Based on the results of detailed audit calculations, the value obtained before improvement was 2.23 kWh/m2/year. The IKE value still includes the criteria for being very efficient or meeting standards. After improvements it became 1.65 kWh/m2/year. Energy saving opportunities are available in indoor and outdoor lighting systems by replacing CFL (compact fluorescent lamp) lamps with Philips LED lamps. Based on calculations, the savings in electrical energy costs are IDR 41,736/day, resulting in savings of IDR 15,233,640/year. Based on the Isc/IL calculation above, it can be seen that the Isc/IL value is 165.4. According to the IEEE 519-2014 standard, the ISC IL value in the range >1000 has a permissible THDi value limit of 15%. The nominal voltage used is 0.4 kV, so the permitted THDv is 8%. Based on table 3.9 THDv and THDi under standard conditions.","PeriodicalId":476257,"journal":{"name":"Elposys: Jurnal Sistem Kelistrikan","volume":"263 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140457511","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a loaded transformer, the power that comes out of the transformer (transformer output power) is not always 100% because there are losses when channeling to the load. Both losses caused by current flowing in the copper wire, losses caused by alternating flux in the iron core, and losses caused by Eddy current in the iron core which result in the outgoing power (output power) from the transformer to the load is not the same as the incoming power (input power) to the transformer. This is known as the efficiency of the transformer. From these problems, the solution offered is to design and implement a transformer using an EI-shaped iron core which is arranged alternately which aims to prevent the occurrence of Eddy Current what happens in the coresolid by applying to the inverter. From the test results of the transformer, it can be concluded that the difference in flux density in the transformer when it is loaded will affect efficiency. The smaller the flux density of the transformer, the better the efficiency, while the greater the flux density of the transformer, the lower the efficiency.","PeriodicalId":476257,"journal":{"name":"Elposys: Jurnal Sistem Kelistrikan","volume":"11 8","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135870873","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One field that has used a lot of technological developments is the CPNS Test which is based on the CAT (Computer Assisted Test) and uses many a lot of laptop/computer devices to support the implementation of the test. The many uses of computers, especially during the recruitment test, influence the quality of electrical power due to the typical character of the PC/laptop load, which is a non-linear single-phase load which results in neutral currents or currents containing harmonics. This is because the load on the pc/laptop has electronic components such as semiconductors where there is a switching process that creates an impure sinusoidal wave that causes harmonics. In the case study, the implementation of the CPNS CAT with the use of PC/laptop devices will certainly cause a fairly high THD and affect the electric current/power source. The thing that needs to be considered with a high THD and the supply of electricity from the generator is the effect on the performance of the generator and the influence of the generator’s lifetime. Briefly, the loading of the data is to reduce the derating generator set by 6,717 kVa so that the safe loading is 23.28 kVa with a maximum capacity of 30 kVa generator. Synchronous generator loading is recommended at 81% of its nominal value with a current THD of 50%.","PeriodicalId":476257,"journal":{"name":"Elposys: Jurnal Sistem Kelistrikan","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135808514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The monitoring panel system is useful for facilitating monitoring of power quality in real time so that the efficiency of electrical energy can be maintained.
