This chapter detects types and structure of ceramic and polymeric insulators. It also sheds light on improving efficiency and high voltage distribution through insulators string toward utilizing nanotechnology techniques. Furthermore, this chapter takes interest in displaying the effects of nanoparticles on overhead transmission lines (OHTL) insulators and high voltage distribution on suspension insulators. The importance and features of using polymeric and non-ceramic suspension insulators have been recently detailed. Thus, this chapter tackles and designs recent models for using individual and multiple nanoparticles in polymeric OHTL suspension insulators. It draws forecasts and recommendations for developing suspension insulators by using nanotechnology techniques.

The paper is devoted to the use of RFID-technology in electrical power engineering, in particular, for controlling the condition of high-voltage equipment of feeding transmission lines. It also describes studies on development of RFID-tag designed to indicate dielectric condition of line polymer insulator. The authors present results of tests of pilot samples of LKi-70/110-4-GP-UKhL1 polymer stick insulators with built-in RFID-indicators. The tests have been executed in accordance with the GOST R 55189-2012 requirements. As a result, the authors have made a conclusion on the possibility of using RFID-technologies for technical control of insulators on overhead transmission lines, high-voltage equipment of traction and transformer substations.

Pollution Flashover

Lighting is one of the important reasons of transmission line trip accident. For 330kV and above ultra high voltage transmission line, lighting flashover more frequently occur. To reduce tripping rate effectively and fundamentally, lightning over voltage level should be analyzed besides anti-pollution flashover. In this paper, a simplified equivalent circuit model of a 330kV overhead transmission lines is established. The lightning over voltage of the transmission is analyzed and calculated. Method to reduce the lightning overvoltage is discussed.
