Abstract

As time goes by, development.Technology is growing rapidly. Life today is all modern and is needed as a source of electrical energy. The increasing need for electrical energy requires the availability of reliable and efficient electrical energy. PT. PLN (Persero) has three levels in the distribution of electricity, including the generation rate, transmission rate and distribution level, causing many problems that occur in it. Problems that occur among them are in power transformers there are power losses caused by several factors. Power losses that occur in power transformers need to be considered, because they can cause a considerable loss of efficiency. Analysis of the calculation of power losses was carried out on a 150 kv high-voltage system at the tripe substation to a 20 kv distribution line. The study was carried out by asking permission from PT. PLN (Persero) Substation tripe and then collect the required data such as power transformer specifications, peak load data and Kwh sales data for a period of 1 year starting from January 2022 to December 2022. The conclusion of the study of the effect of total losses (technical and non-technical losses) on efficiency is that there is a relationship between loads, losses and transformer efficiency. So it can be concluded that the load is directly proportional to the losses of the transformer and inversely proportional to the efficiency of the transformer. If the greater the load, the greater the total losses. So that efficiency is also decreasing,

Abstract

Along with the development of the times, the need for electricity is very necessary. Electrical energy is one of the energy that is needed in using equipment that is related to electrical energy such as household, office and commercial industrial equipment that requires electrical energy. Bawean Island is one of the islands that requires a large amount of electricity due to the growing development of these sectors. With the rapid development of large-scale developments, the need for electricity needs to be increased in order to meet people's demands related to electricity needs. Technical losses are losses that occur for technical reasons where energy is reduced by turning into heat or heat energy. Basically technical losses occur based on energy losses in components caused by errors in the components themselves. Technical losses that occur in distribution transformers are common. In principle, losses always occur because efficiency cannot be 100%. Energy is lost along with distribution from upstream to downstream of distribution transformers. Based on the formulation of the problem taken, the researchers calculated losses at neutral currents, copper losses, total losses, output power and total losses in the form of prices. From the results of the conclusions above, it can be seen that the greater the current in the neutral of the transformer, the more losses that occur in the transformer.

Abstract

Larger and better-quality electricity will be needed due to the increased economic growth of the industrial sector and the development of the city of Surabaya, especially in the Sidoarjo region. One of the devices whose efficiency needs to beined in order to be able to conduct electricity sustainably is a transformer. The transformer that is often installed on the Mainstream or Distribution Guard, serves as a step-up and step-down transformer in power transmission. There were losses in the transformer from the current flowing through the copper wire, losses on the reverse flow of the iron core, and damage from the torque of the current on the iron kernel which caused the transformator to become less efficient. That's why the author took the title "Efficiency Analysis on 60 MVA Power Transformers in Babadan Sidoarjo's Mother's Ward" to refer to it. The objective is to determine the losses and efficiency resulting from the load imbalance that occurs between the phases on the 60 MVA Transformers in the Babadan Sidoarjo Innduk Gardu. The final results of the research conducted can show that the average loss value is (290,4 kW) and the percentage of the average value for efficiency is (99.49%).
