Hazardous Temporary Overvoltages From Self-Excited Large Induction Motors—A Case Study
IEEE Transactions on Power Delivery, 2012Large induction motors, when they become disconnected from their synchronizing source and isolate with part of the high-voltage system, become self-excited as long as their inertia keeps them spinning and there is enough capacitance from the system to provide the magnetizing current for the machine and maintain air-gap flux.

Experimental Study on Temporary Overvoltage Characteristics of MOV Based Surge Protective Devices
Journal of the Korean Institute of Illuminating and Electrical Installation Engineers, 2010Protection against lightning surge is an essential part of almost any electrical and electronic equipment today. Metal Oxide Varistor(MOV) is the single most important component in the overwhelming majority of the Surge Protective Devices(SPD) designated to provide such protection.

Estimation of Temporary Overvoltages during Power System Restoration using Artificial Neural Network
2009 15th International Conference on Intelligent System Applications to Power Systems, 2009The energization of power transformers following a complete or partial collapse of the system is an important issue. This paper presents an Artificial Neural Network (ANN)-based approach to estimate the temporary overvoltages (TOVs) due to transformer energization.

Temporary Overvoltages due to Harmonic Resonance in Long EHV Cables
2007With the increasing recourse to cables in EHV networks the likelihood of low-order harmonic resonance is becoming of even more concern. The scope of this paper is to analyze the overvoltages due to harmonic resonance at the no-load energization of a prospective 400kV-50Hz double circuit submarine cable line. ATP-EMTP analyses are carried out to predict
