Equation (3) shows the fault impedance calculation for a TL, where \(m\) is the percentage of fault location measured from bus R, ZTL is the TL phasor impedance, \(\overline{I}_{L}\) and \(\overline{I}_{R}\) are the phasor fault current contributions of the TL terminals, and ...
INDUCTANCE OF SINGLE TRANSMISSION LINE Using flux linkages, determine the self-inductance, L, of a single transmission line. Calculation Procedure 1. Select Appropriate Equation Use L /i, where L is the self-inductance in H/m, is the magnetic flux linkage in Wb turns/m, and i is the...

The tool has provided two kinds of methods for calculating shielding failure rate:EGM and LPM.According to electro-geometric models, the striking distance S can be expressed by the following relatively simple equation with the lightning crest current as a parameter and can be associated to striking...
In this paper, the SP is proposed as a new type of NES to improve the wind-resistant performance of the transmission tower-line system. In Section 2, the kinetic expression of the SP will be obtained through Lagrangian equation. The internal resonance feature will be discussed and the optimal...
of MC-DBP to transmission line impairments and the associated complexity of the technique are also discussed. The experimental results are verified analytically using the Gaussian noise (GN) model15,16and through numerical simulations based on the nonlinear Schrödinger equation (NLSE) for this ...
Consistent with our assumption that people mix randomly, the force of infection (the rate at which susceptibles are infected per unit time) is assumed to be proportional to the number of infectious people at timet, which is given by the following expression in the equation for the rate of ...
Equation (1) states that the EMF is determined by the mutual impedance \(Z_{{{\text{m}i}}}\) and the load current \(\dot{I}_{i}\). Under the constant current, mutual impedance determines the degree of interference. The simplified Carson’s formula is commonly used in calculating the...
