NORMAL VIBRATIONS OF SAGGING CONDUCTORS OF OVERHEAD POWER LINES
International Journal for Computational Civil and Structural Engineering, 2022 The phenomenon of self-excitation of thermomechanical vibrations of current-carrying conductors, experimentally discovered by academician A.F. Ioffe, is of practical interest as a possible explanation of the phenomenon of galloping conductors of ...

Distortion of location pulses in high-frequency paths of overhead power lines
Известия высших учебных заведений: Проблемы энергетики, 2019 The work is devoted to the features of propagation of electromagnetic signals (20–1000 kHz) along multi-wire overhead transmission lines. For monitoring the status of overhead power lines, a location method can be used. For connection to power lines, the

Measurement and monitoring of overhead transmission line sag in smart grid: A review
IET Generation, Transmission & Distribution, 2022 In a transmission line, sag is intentionally provided to relax the tension on the wire when placed between two terminals. However, thermal stress and extreme weather conditions can cause increases in transmission line sag, which can eventually damage ...

Известия высших учебных заведений и энергетических объединенний СНГ: Энергетика. It is a very challenging task to correctly use weather data to calculate the active power loss due to corona in overhead power lines. One of the significant reasons for this was the problem of accuracy of determining weather conditions and the use of ...

Justification of Ice Melting Power on 10 kV Overhead Power Lines
Advances in Electrical and Electronic Engineering, 2019 The fuzzy multicriteria model of the ice melting system on radial 10 kV overhead power lines was developed. Three criteria were taken into account: the minimum of reduced annual costs for ice melting system, the minimum of amount of electric energy not ...

Seasonal variation of transmission line outages in Peninsular Malaysia [PDF]
, 2017 Researchers have observed the impact of climate changes on overhead line outages. It is known that overhead lines are very prone to lightning strikes due to their height and location which are normally in an open and exposed area.
