Opening a transmission line is equivalent to adding, in parallel with it, another transmission line but having the negative impedance of the same line. This is straightforward if the line is not mutually coupled with other lines in the system. Mutual coupling between parallel and adjacent lines ...
Modelling of mutual coupling in microstrip antenna arrays fed by microstrip line The results of modelling of the coupling between the rectangular microstrip patches in linear arraty are presented. The equivalent circuit in form of a combination of the transmission lines stubs is proposed. It is then...
Parallel transmission lineArtificial intelligenceMutual couplingDistance protectionIn many countries, the parallel lines are widely used in transmission systems due to economic and technical benefits. Distance relays have poor performance on the protection of parallel transmission lines because of the mutual ...
In order to connect a transmission line in the form of a strip conductor 2 separated by dielectric 4, 5 from opposed ground planes, such as a strip-line transmission line, to a transmission line in the form of a waveguide 10, such as a rectangular waveguide, a coupling comprises two cond...
By using the equivalent circuit model with mutual coupling between transmission-lines taken into account and the asymmetrical bifllar even transmission-line theory respectively, the influence on permeability of the variety of frequency was applied to the analysis of transmission-line transformer equivalent...
The invention relates to test methods of mutual impedance and coupling capacitance of transmission lines in parallel. The test method of mutual impedance comprises the following steps that: a head end of one phase test line in a test line accesses a pilot frequency testing voltage and the end ...
Parallel transmission lines are difficult to protect due to mutual coupling between circuits. This paper proposes a Naïve Bayes classifier (NBC) based fault detection and classification technique for protection of parallel transmission line involving inter-circuit faults. NBC is a good classification to...
2.Fordouble-circuit transmission lines, when the two circuit breakers of fault transmission line trip sequentially to immune from its internal faults, the power direction of the sound line may change between forward direction and backward direction.平行双回线中一回线路出现内部故障,由于两侧开关切除不...
The design parameters are as followed: periodic pitch d = 12.4 μm, groove depth h = 12 μm, groove width a = 2.4 μm, and line width w = 6 μm. To prevent significant electromagnetic coupling Scientific Reports | ...
Transmission lines on a PCB are rarely routed in isolation, and they may be routed in parallel with common or differential driving. If we bring a second line near the first line, there is some mutual capacitance and inductance between the two lines, which will affect the current produced in...
