A scheme for controlled islanding to prevent subsequent blackout
TL;DR: In this article, the authors illustrate the way a blackout can be prevented in real time through controlled segregation of a system into a number of viable islands together with generation and/or load shedding.
Journal ArticleDOI
Characteristics of narrow bipolar pulses observed in Malaysia
Noor Azlinda Ahmad,Mahendra Fernando,Zikri Abadi Baharudin,Vernon Cooray,Hussein Ahmad,Z. Abdul Malek +5 more
TL;DR: In this paper, narrow bipolar pulses (NBPs) are considered as isolated intracloud events with higher peak amplitude and strong high frequency emission compared to the first return stroke and other intra-cloud dis...
Journal ArticleDOI
Harmonic components of leakage current as a diagnostic tool to study the aging of insulators
TL;DR: In this paper, a harmonic component monitoring technique was used to study the aging of toughened glass insulators, and the power spectrum obtained from experiment is analyzed for the potential harmonic component as an indicator of aging.
Journal ArticleDOI
Odd harmonics and third to fifth harmonic ratios of leakage currents as diagnostic tools to study the ageing of glass insulators
Nouruddeen Bashir,Hussein Ahmad +1 more
TL;DR: In this article, the leakage current harmonic components of 45 glass insulator samples were investigated and the results indicated that the insulator sample's leakage current waveform and the total harmonic distortion correspond well with degree of ageing.
Journal ArticleDOI
The Leakage Current Components as a Diagnostic Tool to Estimate Contamination Level on High Voltage Insulators
TL;DR: The present study shows the possibility of utilizing the value of strange harmonics up to the 7th component of leakage current as the parameter for the monitoring of leakageCurrent in overhead insulators in the presence of contamination.
