Abstract

The increasing use and use of electricity in Indonesia causes the potential for greater losses in the transmission and distribution system. This causes many problems that arise, one of which is the corona in the transmission and distribution system. Corona mapping can only be detected through several ways, namely sound, light and distinctive smell. In this thesis, the aim is to detect the corona with the characteristics of a distinctive sense of smell, then the results of the detection are compared with the calculated corona losses. This distinctive odor is the smell of ozone which is produced from ionization at high voltage with the surrounding air, namely oxygen to form ozone molecules that are not permanent. The metal electrode to be tested is the copper tip metal. After testing the voltage of the appearance of the corona occurs at 7kV, high voltage when testing the tip of the copper metal point at a voltage of 21 kV is greater than the corona losses. The greater the voltage, the greater the corona losses generated.

Abstract

The availability and reliability of electrical energy has become the backbone of society, so periodic maintenance needs to be carried out to avoid short breakdowns and technical malfunctions as well as to improve electrical and environmental safety. Overhead transmission line is an important part of the transmission network and their health status is an important foundation for ensuring the reliable supply of electricity to the power grid. The health index (HI) is a value that reflects the health status of high-voltage transmission lines obtained by combining the normalization of component ratings on certain parameters and calculation methods. This study shows that the condition of assets, electricity and the environment have an effect on determining the soundness index of the Anyer-Asahimas 150 kV overhead transmission line and can be a guide for its maintenance. The final health index value shows 92.8% meaning that the transmission is not only safe in terms of equipment but also safe in terms of electrical and environmental safety aspects.

Abstract

Good power quality is required in health facilities since the increasing use of microprocessor-based equipment. Poor power quality in the electric power system can cause medical equipment in health care centers to malfunction and give incorrect medical diagnoses. Since 2020 we are facing a new type of Virus (Covid-19), this virus requires special laboratory construction with specific air conditioning systems (temperature, humidity, and pressure) to process specimens. This paper presents measurement results of harmonic distortion characteristic by Variable Frequency Drive (VFD) of Heating Ventilation Air Conditioning (HVAC) system in PCR Laboratory at Clinic A. The VFD in this system is used to adjust the rotation of the exhaust fan and outdoor unit. The measured voltage, current and power are used to assess power quality. The main power quality problems found in medical facilities are voltage flicker, neutral currents, and total harmonic distortion (THD) values. The measurement of total harmonic distortion (THD) is used to find the source of the harmonics. Potential problems can be identified within the facility. The results of this study can be used to develop, test, and validate the system that has been used.

Abstract

Mine Mouth Steam Coal Fired Power Plant (PLTU) has a capacity of 2x18MW while the power supplied to internal consumers is 3.6MW or around 10% of the total generating capacity (20% of one generating unit). To operate according to its specifications, the load is increased by operating the load bank. The small internal load and use of the loadbank cause the cost of generation to be high. Excess generating capacity can be sold to external consumers outside the mining area, so it is necessary to build one circuit overhead transmission line 150kV as long 48.38km. The construction of overhead transmission line 150kV from the PLTU to the external consumer substation can increase sales of electricity and can replace the loadbank function. This study aims to evaluate the technical feasibility and economic aspects of the construction overhead transmission line 150kV from the PLTU to an external consumer substation. The research method uses financial indicators IRR, NPV and ROI. Overall, the construction of one circuit overhead transmission line 150kV can increase sales of electricity and replace the function of load bank. The NPV value is IDR 1,604,887,094 with an IRR of 12.53%, and ROI of 9.03 years.
