No full textVerticality Tower is to identify and measure the extent to which the existence of a tower or communication tower is in the right vertical position. Towers that do not stand vertically can have a serious impact on the stability, performance, and safety of the structure. Therefore, tower verticality surveys are important as part of the management and maintenance of safe and reliable telecommunications infrastructure. Towers that do not stand vertically can experience uneven pressure on their structural parts. This can reduce the stability of the tower and increase the risk of collapse, especially in adverse weather conditions or natural disasters. Towers that do not stand vertically can affect the direction and spread of antenna signals. This can interfere with the quality of communication services provided by the tower. Unstable or imvertical towers can be a threat to the safety of the surrounding community. The risk of tower collapse can cause injury and property damage. The BTS tower studied still has a slope that still includes slope standards (IEC): IEC 62232 Standard, Telecommunications Industry Association (TIA): TIA-222, and ANSI/TIA-222-G which is 1-3 degrees. Height in geographic information systems (GIS) refers to the elevation dimension of a location on the earth's surface. Altitude in GIS is usually obtained from satellite imagery or field measurements, with this information we can assist in modeling and analysis of altitude at various geographic locations
PENGARUH KONFIGURASI DAN KEDALAMAN PENANAMAN KONDUKTOR TERHADAP RESISTANS PENTANAHAN GARDU INDUK TEGANGAN EKSTRA TINGGI (GITET) 500 KV UNGARAN
No full textThe earthing system is one of the most important parts of protection equipment in the substation. In the event of more voltage disturbance, with the earth system causing the current disturbance quickly flowed into the ground. the grounding resistance of a good substation inaccordance with the standard is ≤ 1ohm. The values can be affected by some parameters of the earth system such as the number of parallel conductors, the depth of the conductor cultivation, the distancebetween the parallel conductor, the ground area and the ground type resistance.Test results on GITET 500 kV Ungaran get the value of grounding resistance of 0.22 Ω, then for the actual touch voltagevalue of 698.03 V and the actual step voltage of 369.84 V. However, at the time of modification of grounding parameters, the test results obtained for the highest value of grounding resistance of 0.3400 Ω and the lowest value of 0.2212 Ω, then for the highest value at the actual touch voltage of 2582.40 V from the influence of the number of conductors parallel and the depth of the conductor planting and the lowest value of 893.73 V, while at the actual step voltage the highest value of 1093.60 V and thelowest value of 149.65 V, then for the influence of the number of parallel conductors and the distance between the parallel conductors at the actual touch voltage the highest value of 1634.10 V and the lowest value of 888.56 V, while the actual step voltage is the highest value of 1542.23 V and the lowest value of 447.17 V.
