Miniaturized microstrip window hairpin resonator with T-feeder coupling lines
2012 18th Asia-Pacific Conference on Communications (APCC), 2012In this paper, a new structure of planar hairpin resonator with T-feeder coupling lines was developed. Two symmetrical T-shaped feedlines mounted inside the side-by-side window structure behave as resonators, and they are responsible for maintaining the 50 Ω input/output impedance matching and transforming electrical energy into electromagnetic (EM ...

IEEE Transactions on Power Delivery, 2020
The DC power feeder for railway electrification usually consists of multiple parallel cables for handling high current as well as for redundancy design. A non-intrusive condition monitoring of the DC feeder is proposed for early detection of defects related to poor electrical contact due to ageing and corrosion, as well as accidental damage.

A non-intrusive method for monitoring the health condition of power feeder with parallel cables is proposed and developed. The proposed method is based on an inductive coupling technology and therefore it does not affect the normal operation of the actual electrical system and can be easily deployed on-site without any modification to the feeder ...

Optimal distribution feeder capacitor placement considering mutual coupling effect of conductors
IEEE Transactions on Power Delivery, 1995This paper develops a systematic method of optimally locating and sizing the compensation capacitors on distribution feeders by taking into account the mutual coupling effect among phase conductors. The equivalent circuit models of three-phase, two-phase and single-phase conductors are applied so that the mutual coupling effect could be included in the

Investigation on Structural Design and Coupled Finite Element Analysis of CS 3L Feeder for ITER
Journal of Fusion Energy, 2014The central solenoid (CS) 3L feeder is applied to convey the coolant and electrical energy to the CS as well as house the instrumentation wiring. Due to cryogenic and complex electro-magnetic (EM) environment, CS 3L feeder suffers great thermal contract and huge Lorentz force.

Derivation of cavity coupling to feeder from tuning curves
Proceedings of the Institution of Electrical Engineers, 1965A method of finding a cavity coupling factor Qx from the separation in wavelength between branches of tuning curves obtained by moving a short circuit in the feeder is described. This is complementary to a derivation from slopes proposed earlier. The alternative method is suitable over a large range of Qx (from about 30, where the formulas obtained for

Microstrip Bandpass Filters Using Window Hairpin Resonator and T-Feeder Coupling Lines
Arabian Journal for Science and Engineering, 2014A new structure of planar window hairpin-based bandpass filters with symmetrical T-shaped feeder coupling line resonators is introduced. With varying different width in X axis and length in Y axis of the window of the hairpin resonator configuration, correspondingly the changes can be observed in the resonant frequency and useable bandwidth.
