The Principe is to create artificial zero crossing by the means of resistances injection. The resistances will reduce the fault current smoothly till it reaches zero, it will also absorb the energy in the system.This is done using the following sequence: 1- Sequential insertion of some resistances, which can be performed both through linear and rotative movement. These sequences gradually divide the tension so that it can be interrupted. 2- The resistive elements used have the same shape, but are manufactured out of materials of different resisivity. Thus, a gradual diminution of the current is obtained. 3-When passing from one resistance to another, the electric arc is eliminated by grading the resistivity at the commutation edges. 4- The activation of Ballistic Breaker can be obtained by using: elastic devices, step-by-step engines, gas pressure energy.
Hello, I graduated from faculty of engineering, electrical power and machine department. My Graduation project about high voltage DC and DCCB (simulation by Matlab). I have excellent command on all subject like Circuit analysis and design,Analog and Digital circuit design , electronics , C++ Programming , Power system analysis, power electronics, DC/AC machines , Distribution system and lighting , Automation, high voltage , and protection system.I have experience in different software like Autocad, Dialux , Etap ,C++ language Programming, matlab programming and simulation, Micro-win S7 200_simulator PLC,EKTS_software, LTspice XVII software, and proteus I am working in master in the field of HVDC. I had also services out of scope of engineering which I can provide it like: Data entry and analysis,Translation,Writing Articles, and power point presentation So, Please reach out to me so that we can discuss your project in greater detail.
