Relays, Working principle of relay,

            Introduction:

An electrical relay is a switch which is under the control of another circuit. A classic example of an electrical relay is the system used to start a car. When someone turns an ignition key, the ignition does not interact directly with the car battery.

Grid Substation, Introduction, Grid station and National Grid substations

Grid Substation                                                            

  Introduction:

A grid substation is part of the electricity grid system -i.e. part of the transmission system. In the Bangladesh, this involves voltage levels of 400 kV, 230 kV, 132KV,66,11KV,  KV,440V,220V132 kV.Transmission of power occurs through the power distribution grid.

Recommendation for Future Work ,Results Validated By Theoretical Modeling and Development of Algorithm

Recommendation for Future Work:

          In the whole research work, attention was paid to simulate all the structures by commercial EM software Zeland IE3D. Investigations need to be justified experimentally by VNA and compared with simulated results.

Motivation, Reasoning and the Proposed Proposition of EBG structures and Application of Dumbbell shaped EBGS as BPF

Motivation, Reasoning and the Proposed Proposition of EBG structures

From the intensive literature survey it is clear that the inclusion of EBGSs / dumbbell shaped EBGSs improve the performance of microwave components and devices significantly. From the performance of novel 2-D EBG structures for microstrip lines it is obvious that the performance is hindered by the optimized value of FF.
