Abstract

Current technological developments are very competitive with each other, both in electric power distribution systems or electronic equipment. Disturbances that occur are usually caused by short circuits and ground disturbances, or lightning strikes. These disturbances will result in a voltage drop or increase in voltage, which results in decreased system stability, endangers people's lives, and can damage electronic equipment. Coconut Shell Charcoal has a lower resistivity value than soil and has a larger pore structure to absorb more water, and has conductive properties. The results obtained from the comparison using dry coconut shell charcoal and wet coconut shell charcoal show that measurements using wet coconut shell charcoal are better (less resistance) than using dry coconut shell charcoal. Soil resistivity measurements will be much better at the maximum depth than the usual depth (110 cm), better than 10cm.

Abstract

PT. Semen Padang is one of the largest cement producers in western Indonesia, along with the development of the cement industry PT. Semen Padang added a new Indarung VI factory to support the production process to meet market demand. With the addition of this new factory, a good safety design is needed in the design of the electrical system so that production continuity is not disturbed and reliability values are high. Therefore, over-current protection coordination studies are needed on the electrical system of the kiln area at Trafo 2 Indarung VI PT. Semen Padang to get a safe and reliable system. In the final task, this time will be done modeling, simulation of load flow and short circuit, calculation of relay settings, and simulation of coordination of overcurrent protection phase interference in the electrical system kiln area in Transformer 2 Factory Indarung VI PT. Semen Padang. The plot results of the coordination of the time flow curve obtained through the results of analysis and manual calculations recommended tuning pick-up overcurrent relayand grading time overcurrent relaytuning phase interference. Grading time between overcurrent relay is coordinated by 0.2 seconds. With the protection coordination setting, the electrical system of the kiln area at the Indarung VI factory PT. Semen Padang is safer and more reliable.

Abstract

In a three-phase system, the difference in the angle between the phases and the phase sequence of the system is very important to ensure the system functions normally and does not cause damage to the three-phase equipment connected to the system. Trigonometric formulas in multiphase systems are used to obtain the angle difference between the phases and the sequence of phases in the system. The trigonometric formula was tested in a simulation using MATLAB software, then applied to an Arduino Mega-based system. In the simulation, the data are two voltages vs. time with a certain phase angle difference, then using the trigonometric formula in the MATLAB program, the data is recovered from the phase angle difference and the direction of rotation of the two voltages. Based on the valid MATLAB simulation test results, the program algorithm is embedded in an Arduino Mega-based system equipped with 2 voltage sensors and a 2.4-inch TFT LCD. The Arduino Mega-based system has succeeded in detecting and visualizing in the form of a graph the angle difference between the phases and the direction of rotation of the three-phase system.

Abstract

The power transformer would have happened disturbanced that can cause a failure at a transformer. For this condition needed to maintenance power transformer, one of which is by analyzing transformer oil by using the TDCG method. This analysis is carried out to determine the diagnosis of faults in the transformer. This method are the condition of the analysis which is based on the amount of a gas dissolved on oil a transformer. This study used four methods for transformer failure analysis are TDCG method, Rogers-ratio, gas key, and duval triangle. The results obtained by the TDCG method of dissolved   gas are 1332 ppm, the rogers ratio result a symptom of oil heat a transformer at 300oC, the key gas method results in overheating of oil, and the duval triangle method results in a low breakdown voltage analysis.

Abstract

Fully controlled rectifier and Battery Charge Regulator (BCR). BCR is the main unit of UPS ( Uninterruptable Power Supply ) equipment. The fully controlled rectifier has the function of supplying voltage directly to the BCR, and the BCR has the function of regulating the battery charge. Forced charging the battery at a constant voltage with a current that matches the life of the battery will have an impact on decreasing battery life, besides that it will have an impact on the efficiency of using the battery. Controlling the input voltage of the charging battery as a function of the battery voltage is regulated by the magnitude of the charging current flow. Charging the battery via BCR is adjusted to the battery voltage so that BCR can control it by adjusting the voltage to 13.5 V for High Voltage Disconnected (HVD) and 10.5 V for Low Voltage Disconnected (LVD). Based on the test results of the performance of the full control rectifier system and BCR on a 12 V battery with a capacity of 5 Ah, it shows that the output voltage is A fully controlled 12 V rectifier, the BCR can charge an empty internal battery in a few minutes with a current varying from 2 .1 A to 0.1 A.
