Analysis of Grading Ring Design Parameters and Heat Sink Numbers Effect on Voltage Distribution and Leakage Current in Metal Oxide Surge Arrester
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...
متن کاملSurge Arrester Simulation in Fourier Transients Programs of Transmission Systems
The importance of simulating surge arresters in fast transients programs stems from their useful property as a means of controlling switching overvoltages in EHV and UHV systems. The paper proposes a surge arrester model to be used in conjunction with a transient program based on Fourier transform technique. The validity of the proposed model is demonstrated by computational results.
متن کاملModelling of Metal Oxide Surge Arresters in Simulation Software DYNAST
This paper describes the possibilities for mathematical modelling of gap-less surge arresters in the simulation software DYNAST. This tool does not belong to standard modelling softwares in the field of electric power engineering. However, it may provide some key advantages when compared to more frequently used software such as EMTP-ATP and MATLAB-Simulink. Description of the metal oxide varist...
متن کاملSensitivity Assessment of Lightning Protection Device Aging Effect on Distribution Substation Insulation
Insufficient electrical endurance of equipment and insulation failure against overvoltage is one of the most effective reasons for failure the power line. Lightening, switching or other disruptive parameters can cause line outage or distribution substation failure. There are different devices used to improve the safety, reliability, and power quality of the system. Surge arresters are one of t...
متن کاملMetal-oxide surge arrester model for fast transient simulations
Metal-oxide surge arresters have dynamic characteristics that are significant for overvoltage coordination studies involving fast front surges. Several models with acceptable accuracy have been proposed to simulate this frequency-dependent behavior. Difficulties arise in the calculation and adjustment of the model parameters: in some cases iterative procedures are required, in others the necess...
