KARAKTERISTIK TEGANGAN TEMBUS AC PADA MATERIAL ISOLASI PADAT CAMPURAN EPOXY RESIN DENGAN TONGKOL JAGUNG
Full text linkAbstrak – The development of insulation in electric power systems meets the optimal level of reliability. This phenomenon is a challenge in finding new materials to isolate electricity use. One of the insulating materials being developed is an epoxy resin polymer material. This study aims to describe the characteristics of epoxy resin composites added with corncob ash filler as a high-voltage insulation material. The cob ash filler, which is known to contain silica resistant to high temperatures, has good inhibition and can increase mechanical strength. This study was conducted using a direct experimental method in which the isolation of epoxy resin was mixed with corncob ash filler with a mixed variation of 0.5 g, 1 g, 1.5 g, and 2 g. The results show that the more corncob ash filler in the epoxy resin, the faster the failure to penetrate the insulating material made. The breakdown voltage value is 21.64kV on pure epoxy resin insulation material, 10.28kV on a mixture of 0.5 gram corncob ash filler and epoxy resin, 8.93kV on a mixture of 1 gram corncob ash filler and epoxy resin, 7,81kV on a mixture of 1,5 grams corncob ash filler and epoxy resin, and 7,26kV on a mixture of 2 gram corncob ash filler and epoxy resin.Abstrak

ANALISIS KINERJA PMS REL 2 BAY TRAFO 6 MENGGUNAKAN THERMOVISION METHODE DI GARDU INDUK SUNYARAGI
Full text linkIn an effort to provide reliable and efficient electrical energy, substations have an important role in regulating the demand for electric power loads and as a center for securing electrical power system components in a certain area. Frequent disturbances become a benchmark for an electric power system whether or not it is good or not in an effort to provide reliable and efficient energy. One of the maintenance measures is temperature measurement using thermal imagers, which is commonly referred to as thermovision measurement.Thermal imager is a tool that can be used for predictive maintenance activities to monitor the condition and performance of an equipment so that the possibility of equipment failure can be minimized. In October 2020, after thermovisiting transformer bay 6 at the Sunyaragi substation, it was discovered that there was a hotspot on the T-phase separation blade, causing heating of the blade, the above conditions can result in a decrease in PMS performance, with the worst condition if left alone can result in damage to the PMS blade and can also melt when the peak load is on the transformer 6. Under these conditions, maintenance is carried out by maintaining contact resistance, insulation resistance, and grounding resistance. The results of the analysis of contact resistance after maintenance show that the equipment is in good condition and still suitable for use, with a value of 7μΩ for the R phase, 6.5μΩ for the S phase, and 6.7μΩ for the T phase
