"The new edition of this book incorporates the recent remarkable changes in electric power generation, transmission and distribution. The consequences of the latest development to High Voltage (HV) test and measuring techniques result in new chapters on Partial Discharge measurements, Measurements of Dielectric Properties, and some new thoughts on the Shannon Theorem and Impuls current measurements.This standard reference of the international high-voltage community combines high voltage engineering with HV testing techniques and HV measuring methods. Based on long-term experience gained by the authors the book reflects the state of the art as well as the future trends in testing and diagnostics of HV equipment. It ensures a reliable generation, transmission and distribution of electrical energy. The book is intended not only for experts but also for students in electrical engineering and high-voltage engineering."

"This paper deals with the electrical insulation of a gap bridged by a solid dielectric between a pair of electrodes in a vacuum, where the dielectric is a model of an insulating spacer holding electrodes in various vacuum devices. Such gap configuration is typical as a model for studying physical mechanisms of an electrical breakdown or a flashover in a vacuum, in which the insulation ability isconsiderably lower than a gap without any insulating spacers. Many researchers have long investigated the mechanisms of flashover, and it is believed that the charging of the insulator surface is the primary drive of such weakness. One of the effective approaches for studying mechanisms is to analyze the characteristic of charge accumulated on the insulator surface both by experiments and bynumerical analyses. This paper reviews previous works conducted by the author’s research group and demonstrates the difficulties we have encountered upon conducting the numerical analyses."

"ABSTRACTHigh Voltage measurement based on the electro-optic effect of LiTaOa crystal plate has been developed. This crystal was placed between two parallel plates which more like capacitor arrangement. On the first step, this system was capable only to measure the do voltage from 0 to 1 kV, and the ac voltage from 0 to 0.3 kV. But, by enlarging the spaces in between one side at crystal to one of the plate surface, d, the range of measurement was increased up to 4.8 kV, with d =7 mm."

"Sistem proteksi sangatlah penting dalam sistem tenaga listrik, terutama untuk kehandalan kerja dan perlindungan pada sistem dalam mesin-mesin listrik. Rele merupakan salah salah satu alat proteksi yang banyak digunakan pada sistem tenaga listrik. Jenis rele bermacam-macam tergantung karakteristik yang dibutuhkan, salah satunya adalah rele jarak dan rele diferesial penghantar. Pada PT. PLN, penggunaan sistem proteksi mutlak diperlukan untuk mendukung kinerja sistem tenaga listrik karena sebagai perusahaan listrik negara, PLN merupakan gardu terdepan dalam pendistribusian listrik di seluruh Indonesia sehingga tentunya diharapkan keberlangsungan sistem listrik tidak terganggu.Pada skripsi ini, penulis akan mengangkat topik tentang konfigurasi proteksi dimana pada sistem transmisi SUTT (Saluran Udara Tegangan Tinggi) di daerah Alam Sutera akan dibangun gardu induk baru sehingga dengan adanya penambahan sistem, konfigurasi sistem proteksi yang lama perlu diperbaharui untuk menyesuaikan dengan sistem yang baru secara keseluruhan. Karena fokus lebih diutamakan pada proteksi utama, maka rele yang akan dibahas pada skripsi ini adalah rele jarak dan rele diferensial penghantar yang biasa digunakan pada SUTT. Untuk melihat koordinasi rele setelah perhitungan, akan digunakan metode scanning untuk melihat hubungan koordinasi antar rele dalam sistem yang baru. Sehingga di dapatkan hasil rekonfigurasi dan pengaruhnya pada sistem sebelumnya.

Protection system is essential in an electrical power system, especially for the reliability and protection on the system in electric machines. Relay is one of the devices that is widely used in the protection system of electric power. There are various types of relay based on characteristics that are required on system, two of them are distance relay and line differential relay. In PT. PLN, the usage of protection system is undoubtedly needed to support the performance of electrical power systems because their position as main electrical company on the state, PLN is forefront for electrical distribution throughout Indonesia so it is expected that sustainability of the electrical system is not disturbed.In this thesis, the author will discuss the topic of protection system configuration about the high voltage overhead power line of transmision system in the area of Alam Sutera where the new main substation will be built. To adjust this new system as a whole, the old protection system needs to be updated. This thesis will focus in main protection of the system, the relay that will be discussed on this thesis is distance relay and line differential relay which commonly used in high voltage overhead transmission line. For the simulation of distance relay coodination, scanning method will be used to see the relation of coordination of the relay on the new system. Therefore the result can be gotten by reconfiguration and the impact for the previous system."
