This research develops a method for determaining catenary sag and tension analysis on 275 kV transmission line conductors. Catenary method is a function of the weight equation conductor, wires maximum tensile stress, long-span, and the maximum sag of the conductor. Processing methods was is used to determaine the value of the sag and tension with the design of the model using statistical softwa…

Perkiraan Umur Transformator Berdasarkan Pengaruh Pembebanan Dan Temperatur L…

Base on overloading conditions and the exposure of ambient temperatures that exceed the standard level, will causes thermal aging of the insulation on the transformator,which can causes “shrinkage” the age of it. Sampling of the transformator that used in this research,is the power transformator. Both of it,have been installed from 2010 (tranformator 3) and 2015 (transformator 4) at major …

Analisis Tegangan Lebih Transien Impuls Pada Mixed Transmission Line (Sutt-Sk…

The distribution of electrical power from the power plant to the center of the load on the transmission line can occur the electrical fault. This fault that often occurs is a transient overvoltage caused by a direct lightning stroke. Lightning stroke can cause the lightning impulses which are the dominant factor in generating the transient over voltages on 150 kV overhead lines compare to the h…
