Estimation of parameters for faulted transposed transmission lines
(2018-12-31)
This paper presents a method to estimate transmission line parameters for transposed lines from faulted current and voltage measurements at the line's terminals, in the time domain. The measurements are transformed to the ...
Simplified procedure to estimate the resistance parameters of transmission lines
(2013-09-01)
An alternative and simplified procedure is described to estimate the longitudinal resistances of transmission lines based on the real-time load profile. This method proposes to estimate the resistance parameters from the ...
Evaluation of a genetic assay for canine transmissible venereal tumour diagnosis in Brazil
(Wiley-Blackwell, 2017-06-01)
The canine transmissible venereal tumour (CTVT) is a transmissible cancer that is spread between dogs by the allogeneic transfer of living cancer cells. The infectious agents in CTVT are the living cancer cells themselves, ...
Comparing lumped and distributed parameters models in transmission lines during transient conditions
(2014-01-01)
The solutions of differential equations of transmission line are generally difficult to obtain due to the convolution integral present. Considering this, there are models proposed for the study of electromagnetic transients ...
Line maintenance within transmission expansion planning: a multistage framework
(Inst Engineering Technology-iet, 2019-07-23)
Maintenance in transmission networks is an economical way to reduce upgrading network costs without decreasing its reliability. Hence, new studies regarding transmission expansion planning (TEP) must take into account the ...

(IEEE, 2012-01-01)
In this article, it is represented by state variables phase a transmission line which parameters are considered frequency independently and frequency dependent. Based on previous analyses, it is used the reasonable number ...
Applying a new methodology to verify transmission line model performance - the equivalent impedance test
(IEEE, 2001-01-01)
The objective of this paper is to present a methodology to analyze a transmission line model used in electromagnetic transitory simulators, called equivalent impedance test. Initially the definition of equivalent impedance ...
Transmission network expansion planning considering phase-shifter transformers
(2012-04-23)
This paper presents a novel mathematical model for the transmission network expansion planning problem. Main idea is to consider phase-shifter (PS) transformers as a new element of the transmission system expansion together ...
