This paper describes the results of research on the effect of profile factor on leakage current of four types of 20kV-post insulators in dry and wet clean conditions. The high ac voltage applied to the post insulator during experiment was 25kV corresponding to the highest voltage on a 20kV system. The level of insulator wetting has been referred to the average daily rainfall data in Indonesia. Three common rainfall values have been considered, namely 20mm, 50mm and 100mm, which are equivalent to the amount of watering level of 16ml/s, 30ml/s, and 60ml/s respectively. The results showed the significant effect of profile factor on the level of leakage current of post insulator both in clean dry and wet conditions.

Wall material is an important factor to define inside comfortable rooms and building energy consumption for air conditioning (AC). Controlling inside room temperature methods were used to analyze the energy costs for the ACs. The proposed study is to find out the impact of materials on inside room temperature and energy cost for ACs. A simulation study illustrates the effect of wall materials to define inside room temperature. In this research, an innovative material was built from mixed materials (such as: Styrofoam, soil and cement). The characteristics of material relates to heat transfer coefficient (Q), thermal conductivity (k) and output temperature (T2). Two kinds of steps were conducted to achieve this goal., Firstly, a simulation process was applied to define the temperature output of the innovative material. Secondly, energy costs were calculated based on the characteristics of this material under a simulation process. The results of research indicated that Q, k and T2 of an innovative wall material is effective in reducing energy cost for ACs.

Ferroresonance is a transient phenomenon characterized by overvoltage and waveform mismatches affected by a combination of nonlinear inductances and capacitors. Even though ferroressonance is a transient phenomenon however the impact of the ferroresonance continue for a steady state that causes excess temperature and finaly damage the impacted apparatus . Therefore, this study concern to understand and identify ferroresonance phenomena and at the end to distinguish them from other disturbances such as overvoltage and harmonics. Ferroresonance initiation is carried out on a laboratory scale using a basic circuit of ferroresonance consisting of capacitors and transformers. Two kind of transformer core topologies, namely H type and M type, was used in the experiments. Moreover other disturbances such as harmonics was also simulated in laboratory. The ferroresonance and harmonic waveform then be processed using wavelet transformations and its cumulative energy was also determined. The results shows that for H type transformer the threshold value that distinguishes ferroresonance from other disturbances is about 9.24. On the other hand for M type transformer was about 7.97. Based on these values, the type of transformer core affect the energy level of ferroresonance. Moreover wavelet transformation could identify between ferroresonance and other disturbance under study very well, however further study should be done to investigate the effectivity of wavelet to discriminate all possible mode of ferroresonance.

Boost power factor corrector (PFC) is widely used in various electronic devices due to its advantages of high efficiency, simple structure, low input current ripple and low conduction loss. However, the applications of the conventional boost structure are gradually limited as the output power demand is continuously increasing.In this paper, an interleaved voltage-doubler boost PFC with coupled inductor is proposed. It has the advantages of high efficiency, high power factor and low harmonics. The proposed interleaved control strategy not only retains the advantages of traditional single-phase boost converters, but also reduces the volumes of energy storage inductor, output capacitor and EMI chopper at high output power. A coupled inductor is used to reduce the weight of the converter. The voltage doubled capacitors are alternately charged through a two-phase interleaving operation. Therefore, the voltage gain of the proposed converter is twice that of the conventional interleaved converter and it is suitable for high voltage applications.
升压功率因数校正器(Boost power factor correction, PFC)以其效率高、结构简单、输入电流纹波小、导通损耗小等优点被广泛应用于各种电子器件中。然而，随着输出功率需求的不断增加，传统升压结构的应用逐渐受到限制。本文提出了一种带耦合电感的交错倍压升压PFC。它具有效率高、功率因数高、谐波低等优点。所提出的交错控制策略不仅保留了传统单相升压变换器的优点，而且在高输出功率时减小了储能电感、输出电容和EMI斩波器的体积。耦合电感用于减轻变换器的重量。电压倍增电容器通过两相交错操作交替充电。因此，该变换器的电压增益是传统交错变换器的两倍，适合于高压应用。

Indonesia is a tropical maritime country, has abundant of sea product including in the Gresik Regency which has aquaculture products of 79 thousand tons per year and marine catches of 18 thousand tons per year. Drying is one of the methods to store fishery products longer. Conventional drying carries out with the medium of wind and sunlight. However, contamination of dust and other impurities cannot be avoided from conventional drying. Therefore, fish drying research will be carried out using a hybrid method with thermal collectors and solar panels to harvest solar energy which lead to increase efficiency and overcome the disadvantages of conventional fish drying. This tool model refers to the design of solar powered fish dryers with the development of additional thermal aisles and solar panels. The design of this study uses solar energy that is converted to heat through thermal collectors and cabinet spaces that resemble the greenhouse effect. Photons in solar energy are converted into electricity and become mechanical energy that will move the blower, that converted by photovoltaic. Air enters from the blowers to the thermal tunnel whose base is made of black plate as a thermal collector and the envelope is made of glass. Then hot air is brought to the cabinet drying chamber containing fish. The fish receives heat from the thermal collector and the cabinet system which also receives heat from the mirror installed on all three sides of the cabinet. Hot air containing moisture will come out on the cabinet's top shelf. The performance of dryers is measured by the value of efficiency and the quality of the fish. Based on experimental study, the efficiency of solar dryer is 43.15% and the bacteria test is 45 x 107 CFU/ml.

Lightning protection of substations is a crucial element of the overall insulation coordination approach used in power systems. IEEE Std. 998 (2012) is the world’s leading standard for providing guidance to engineers designing lightning protection for substations. It includes various methods for achieving protection corresponding to the equipment BIL. In this paper, the principles behind one of these methods, the "leader inception theory", are presented. A description is provided of how the method is implemented with a computer program via an example of a real substation. Effective interception of lightning relies not only on the method but also the hardware used. Hence, the paper also discusses the importance of corona minimization from air terminals during the period preceding the descent of the downward leader. The methodology and results of a new series of corona performance testing carried out on a variety of air terminals in a high-voltage laboratory are presented and discussed.

The power transformer is a primary part of the transmission line, PT. PLN (Persero) UPT Karawang as a maintenance unit must ensure the power transformer can operate sustainably. One of the most important from power transformer is the oil insulation because they function not only as a coolant but also as insulation. Water content is the main enemy of insulation because of the water content impact on the actual operating conditions and the lifetime of the transformer. To control that, PLN already implemented characteristics testing for decades as a method to assess the condition of power transformers. The increasing the value of water content in the transformer can be caused Ingress of moisture from the atmosphere, degradation of insulation and error during sampling and testing.

Within Asset Management, decision-making on asset is critical. One crucial decision is to justify whether the asset condition is good or bad based on a set of norms and knowledge rules. For practical reason, the utility usually adapts the norms or rules from manual books or the known international standards or surveys. However, not all norms were ready to use or suitable for the local operating conditions. This paper provides methodologies to develop norms for condition assessment of HV Apparatus with a case study of Gas Insulated Switchgear (GIS) operating under tropical conditions. The methods include the statistical analysis on the field data, expert judgment, comparison with the sister component, and laboratory work. The proposed methodologies offer a better accuracy during condition assessment, and alternatives in developing norms, especially in the absence of international standards or surveys.

Bali is part of a subsystem on the Java-Bali interconnection system. The peak load in the Bali subsystem is 900 MW on February 26th, 2019, at 19.30 WIB. Electric power in the Bali subsystem is supplied from power plants in Bali and transferred through 150 kV submarine cables from power plants in the East Java.In the period 2019-2028, Bali's subsystem peak load continued to increase from 932 MW to 1625 MW. The demand for electric power in Bali is increasing meanwhile the power transfer capacity through submarine cables and power generation capacity in the Bali subsystem is limited. On the other hand, 39 % electricity generation in Bali using fuel oil which have limited operations by government policies. With these conditions, it is predicted that in 2021-2023 the Bali subsystem will be deficit.In this paper will present the composition of energy, the type of technology and the cost of electricity production by considering objective functions and constraints until 2028 to overcome the deficit in the Bali subsystem
