Sistem transmisi merupakan sistem yang sering terkena gangguan sambaran petir terutama langsung mengenai kawat tanah maupun menara berpotensi menyebabkan back flashover (BFO). pentanahan bertujuan untuk mengamankan peralatan-peralatan listrik dengan cara mengalirkan arus ke tanah, salah satu faktor mendapatkan nilai kecil yaitu memodifikasi tahanan zat aditif bentonite, arang dan garam. Penelit...

Metal oxide surge arresters (ZNO) are used widely in power system to protect equipments from over voltages. Non uniform potential distribution leads to the depressed service life and low safe reliability, so grading ring is applied on HV surge arrester order to uniform the electric field distribution. One of the problems of arresters is leakage current in power frequency that different paramet...

Abstract The construction of modular digital smart grid, as a result, the complexity power grid is increasing and new technologies schemes are emerging, more sophisticated design means needed. Therefore, author puts forward research on intelligent three-dimensional substation. emergence 3D has changed status quo difficult collaboration among multiple disciplines under traditional mode, improved...

Aircraft Arrester Barrier Systems (AABS) are installed at the end of the runway to overcome the runway length on war ships. This system is used for the purpose of stop the combat aircraft due to aborted take-off and emergency landings. The conventional AABS is uncontrolled and highly non-linear system during the operation of aircraft arrestment system. Energy absorbing system is an important pa...

The operation of parallel surge arresters can improve energy absorption capability if the are similar and installed close to each other. However, it has been reported that any small difference in individual V-I characteristics lead unbalance current sharing. When some distance away from other, travelling wave effects modify effectiveness for overvoltage protection and, this case, detailed simul...

A novel early streamer emission (ESE) lightning air terminal system is designed and fabricated. By comparing the intercepted artificial lightning striking numbers of the new ESE lightning protection device and the conventional lightning rod (CLR) lightning protection device in laboratory, the effectiveness of intercepting the artificial lightning strokes by the new ESE lightning protection devi...
