Abstract

An overhaul is a process of dismantling a problematic engine so that it can be examined more thoroughly. During the overhaul, the problematic engine components are replaced. The overhaul of the sphere gap setting of the semi-automatic high impulse voltage generation is also intended to maximize the K3 system and the level of accuracy when conducting research on impulse voltage generation. The current condition after the occurrence of damage to the automatic sphere gap adjustment machine. The sphere gap setting is done manually, causing the desired ball gap distance to be not very accurate, and the risk of work accidents is higher in the high voltage laboratory. In the first stage of work, an inspection and measurement were carried out to replace the capacitor and limit switch components because they could no longer be used. As well as improvements to the electromagnetic brake components. From the test results, it was found that the distance measurement was as expected and it can be proven that after an overhaul, the semi-automatic spacer can function normally again so it can make it easier to conduct high voltage impulse research. In addition, from a security point of view, it is better because the spacing between the balls is done outside the high-voltage impulse generation cage

Abstract

The Industrial Electronics Practicum is an advanced learning process complementing theoretical knowledge and is mandatory for every student in the Energy Conversion Engineering (TKE) Study Program at Ujung Pandang State Polytechnic (PNUP). Nevertheless, its implementation is often suboptimal due to the lack of practicum modules available in the TKE Laboratory. To address this issue, this research aims to design and create a practicum module for a controlled single-phase rectifier, filling the gap in the TKE Laboratory's offerings. The design carried out in this research begins with thyristor selection, control circuit design, mechanical design, and power circuit design. After the design is carried out, it continues with manufacturing and assembly, tool testing, and data analysis. In the practical module testing, this controlled single-phase rectifier uses half waves, with a resistive load (R). The test results of the module that has been created show that this practical module can operate well and produce an output waveform that can be said to be in accordance with theory.
