Propagation of surges in stator winding of large AC motors
1989 Edition, January 1, 1989 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The impedance and admittance matrices of the ten-turn coils of a 3.3 kV, 1 MW induction motor stator winding are calculated using a finite-element package. Using multiconductor transmission line theory the Z and Y matrices are manipulated to explain...

Surge and High-Frequency Propagation in Industrial Power Lines
1986 Edition, Volume IA-22, July 1, 1986 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Laboratory measurements were made on a three-conductor line, with or without steel conduit sheath (typical of single-phase 120/240-V systems), to determine the attenuation of surges and the response to steady excitation at frequencies...

Measured Propagation of Surges in the Winding of a Large A-C Motor
1986 Edition, Volume EC-1, March 1, 1986 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper presents the results of impulse tests performed at Ontario Hydro on a portion of a motor winding. The objective of these EPRI funded tests was to determine the wave propagation properties of the motor coils....

Surge behavior on the single conductor with a discontinuity
2016 Edition, September 1, 2016 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper addressed surge propagation on a vertical line with a discontinuity. A formula of surge reflection coefficient expressed by specially-defined surge impedance was introduced, which is similar to that of a conventional transmission line. The...

Fault Classification of Power Distribution Cables by Detecting Decaying DC Components with Magnetic Sensing
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Fault classification of power distribution cables is essential for tripping relays, pinpointing fault location, and repairing failures of a distribution network in the power system. However, existing fault-classification techniques are not totally...

Field measurements and model comparison for a very long submarine HV AC three-core cable
2019 Edition, June 1, 2019 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The availability of three-core, XLPE-insulated AC HV and EHV cables is allowing the installation of very long AC cable systems. Accurate and reliable cable models are necessary in order to assess the behaviour...

Propagation of Switching-Surge Wave-Fronts on EHV Transmission Lines
1962 Edition, Volume 81, April 1, 1962 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper describes the propagation characteristics of switchingsurge wavefronts generated by energizing, or ultrahigh-speed re-energizing, EHV (extra-high-voltage) transmission lines of intermediate length. The description is supported by field...

A Three-Phase Grid-Connected Micro-Inverter for AC Photovoltaic Module Applications
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Photovoltaic (PV) micro-inverter converts the DC from a PV panel to AC directly, which has the advantages of improved energy harvesting, friendly "plug-and-play" operation, enhanced flexibility/expandability, excellent system redundancy and no DC...

A simple computational method for predicting magnetic field in the vicinity of a three-phase underground cable with a fluid-filled steel-pipe enclosure
1995 Edition, Volume 10, January 1, 1995 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper presents a simple computational method for predicting the magnetic field above ground, generated by an underground three-phase pipe-type cable. In the computation, an approximation is made to simplify the problem, a...
