A new method of measuring the change in the average height above ground of horizontal high-voltage overhead transmission-lines (OHTLs) phase conductors is introduced. The new technique, called power-line carrier sag (PLC-SAG) for short, determines av

The known limitations of classical mesh and nodal methods of analysing linear electrical circuits are described before considering an established modification of the nodal approach. The method, known as 'modified nodal analysis', has none of the limi

The frequency-dependent aspects of transmission line transformation matrices along with their asymptotic behaviours at high and low frequencies are thoroughly investigated in this paper. The Newton-Raphson (NR) method for evaluating the transformatio

When an EHV transmission line is energized by the closing of a circuit breaker, there are a number of well known parameters which effect the transient overvoltages on the line. These include the impact of pole closing span, use of closing resistors a

In this paper, the chain matrix theory of multiconductor systems has been applied to the analysis of long cross-bonded cable systems. In order to highlight the power of the method, typical results of transient voltage waveforms at various points of a

The advent of low-power-requirement electronic distance relays has lead to the possibility of generating low-power test signals for such relays using a minicomputer. Such a test program has been written, for steady-state and transient, i.e. dynamic,

The paper considers transient induction from an undergound power circuit into an adjacent pilot cable. Results, in the form of transient waveshapes, are given for a number of representative cases in response to step-type energisation of one of the po

A mathematical model of a single major section of a crossbonded cable system is developed, and an outline of the Fourier-transform method of determining transient-voltage waveforms in the system is presented. Crossbonded cables are analysed in terms

The analysis presented relates to conductors parallel to the plane boundary of two semi-infinite, homogeneous media and to exponential wave propagation, but does not involve any of the previously necessary additional, simplifying assumptions. General
