IN PART 1 last month, we took a back-to-basics approach and discussed line impedance
and its effects on signal integrity.
And the characteristic in low frequency range is mainly decided by transformer leakage reactance and line impedance
of middle and low voltage network to PCC.
As the line impedance
or length increase, TPCMT will boost up its resistance calculation accuracy.
Moreover, research work in  analyzes the impact of the line impedance
on the diversity in the voltage profile of each wind turbine and describes a voltage-profile-based approach to develop multiple-machine aggregated WPP.
These two new line impedance
stabilization networks offer a unique approach to e-mobility as well as help meet the need for increasing voltage and current values inside vehicles.
With a spectrum analyzer and line impedance
stabilisation network added to the mini laboratory, conducted emissions can also be measured on AC power cords.

From the line impedance
in short circuit and open circuit, to extract the propagation parameters of a transmission line, we can measure the S11 reflection parameters in two different configurations, namely, the line in short circuit and the line in open circuit .
Simulated TDR line impedance
responses (which corresponds to voltage potential) of a simulation model of the designed 10-cm-long CPW line with shorted, open, and resistive loads in terms of signal time are presented in Fig.
The impedances [Z.sub.r] and [Z.sub.oe] are arbitrarily chosen to be equal to 110 [OMEGA] and 60 [OMEGA] respectively, which are typically in the range of realizable microstrip line impedance
with a substrate thickness of 1.6 mm and [[epsilon].sub.r] of around 4, while [Z.sub.oo] is given by Equation (9) to be equal to 31.13 [OMEGA].
capacitance resulting in the reduction of line impedance
, while in the case of odd mode, the line impedance
is slightly increased because the distance of coupling to the PEC boundary of a unit cell are also increased, reducing p.u.l.
