  • Determination of the Phase Sequence and Voltage Level of Overhead Conductors Using Non-contact Sensors

    This paper describes how the phase sequence and voltage level (132 kV, 275 kV or 400 kV) of single-circuit overhead conductors can be determined from the measurements which are made by passive, non-contact sensors situated on a moving platform at ground level. The investigation relies on sensing of the electric field along the lateral profile beneath overhead conductors. Firstly, the passive sensor fabricated is described together with an analysis of its performance. Then experimental results obtained in the laboratory have led to the determination technique of voltage level and phase sequence from the spatial variation of the amplitudes and phase angles of electric field. 1 kHz AC supply has been used to energize overhead conductors rather than 50 Hz supply. This greatly improves the signal noise ratio (SNR) of induced voltage measured and makes the investigation of electric field in vicinity of conductors with low-level voltage possible in the laboratory. Finally, investigations made in a 400 kV substation in the UK shows that the proposed technique can successfully evaluate the phase sequence and voltage level of high-voltage overhead conductors

  • IEEE Draft Standard for Calculating the Current-Temperature Relationship of Bare Overhead Conductors

    A method of calculating the current-temperature relationship of bare overhead lines, giventhe weather conditions, is presented. Along with a mathematical method, sources of the values to be used in the calculation are indicated. This standard does not undertake to list actual temperature-ampacity relationships for a large number of conductors nor does it recommend appropriately conservative weather conditions for the rating of overhead power lines. It does, however, provide a standard method for doing such calculations for both constant and variable conductor current and weather conditions.

  • Non-contact determination of the phase sequence and voltage level of overhead conductors in air insulated substations

    This paper describes how the phase sequence and voltage level (132 kV, 275 kV or 400 kV) of single-circuit overhead conductors can be calculated from measurements made by passive, non-contact sensors situated on a moving platform at ground level. The investigation relies on sensing the electric field along the profile of the conductors through the use of passive sensors. The fabrication of the passive sensor is described together with an analysis of its performance. The variation of the vertical component of electric field strength along the lateral profile beneath single-circuit conductors has been studied using finite element modeling software, ANSYS. The results of this simulation have led to a proposed method of determining the magnitude and phase sequence information from overhead conductors via analysis of the induced voltages on the sensors. The paper concludes with an investigation made in a 400 kV substation in the UK. Analysis of the experimental results shows that the proposed technique can successfully evaluate the phase sequence, voltage level, the spacing between phases and the orientation of high-voltage overhead conductors

  • Selection of overhead conductors type and tension for Israeli terrain and weather conditions

    The selection of overhead transmission and distribution line conductors and conductor tension have a direct impact on the building cost, electric losses and reliability of the line. As a result of the research carried out by The National Network Unit of the Israel Electric Corp., a new company standard was developed to regulate strength and tension of the overhead conductors. This standard is adapted to Israeli terrain and weather conditions, based on line operation experience. The permissible conductor tension increased; the conductor tension with no wind is limited in terms of tension-to-weight ratio, preventing damage resulting from aeolian vibrations. The new standard enables new approaches to power transmission and distribution line design, re- conductoring and uprating. Wide use of all aluminum conductors is enabled, both in new and in existing lines, saving power losses. Lighter OPGW conductors can be installed on old lines not overloading the pole heads. ACSS is considered as a line uprating option. On the other hand, dangerous overtension of especially strong conductors is prevented.

  • Radial thermal circuit model for overhead conductors based on parameter identification under natural convection condition

    Ampacity, sag, creep and annealing of overhead high-voltage conductors are influenced by the radial temperature distribution. In this paper, a radial thermal circuit model in the form of state equation is established, and parameters are identified by linear regression method. Polynomial relationships between current level and model parameters are fitted based on the identification result. A radial temperature experimental platform is designed to measure the temperature rise process of ACSR400/35 conductor under natural convection condition. The comparison between calculation and experimental results reveal that the errors of radial thermal circuit model are less than 3%; study based on a 3-bus system indicates that the proposed model provides a more conservative estimate for power dispatching. Thus, it's believed that the proposed model is more suitable for estimating radial temperature distribution of conductors under natural convection condition.

  • Advanced aging failure model for overhead conductors

    Aging failure modeling is a fundamental requirement in reliability assessment of any actual power system. The level of model detail can potentially reflect realistic means of reliability indices. In that context, this paper proposes an advanced aging failure model for overhead conductors, incorporating the effects of loading and weather conditions into the unavailability calculation. The Arrhenius life-temperature relationship is used to model the lifetime of conductors as a function of temperature. The life measure of the Arrhenius model is adopted as the scale parameter of the Weibull probability distribution. The approach to estimate parameters of the resulting Arrhenius- Weibull distribution is described in detail. Unavailability calculations are performed using the proposed aging failure model for a distribution test system. The results show that if the maximum continuous operating temperature is exceeded, the unavailability of overhead conductors increases depending on both time period, where the conductor temperature is higher than the threshold, and conductor age.

    The author discusses the original paper ("Effect of elevated temperatures on mechanical properties under steady-state and short-circuit conditions of overhead conductors", F.

  • The dynamic loading of overhead conductors on 11kV lines

    The behaviour of overhead conductors under varying mechanical load conditions is of great practical importance in the operation of distribution systems. Consequently the field of sag/tension calculations under any combination of conditions is well developed, and has been widely practised by electricity supply industry for many years. However in recent years, some concern has been raised that aluminium based conductors do not always perform as expected. In addition concern about the effects of severe weather on distribution systems has been mounting. The author discusses the behaviour of conductors subject to severe weather conditions, and describes some experimental work currently being undertaken to investigate this area.<<ETX>>
