Uhf and Acoustic Partial Discharge Localisation in Power Transformers
The reliability of electrical energy networks depends on the quality and availability of electrical equipment like power transformers. Local failures inside their insulation may lead to catastrophic breakdowns and can cause high outage and penalty costs. Beside the strength and type of a PD, the geometric PD position is of major interest concerning risk evaluation of the flaw. Conventional PD m...
متن کاملPartial Discharge Monitoring of Power Transformers by UHF Sensors
The reliability of electrical energy networks depends on both, the quality and the reliability of its electrical equipment, e.g. power transformers. Local failures inside their insulation can lead to breakdowns and hence to high outage and penalty costs. Usually, power transformers are tested on partial discharge (PD) activity before commissioning. UHF PD monitoring can be used to prevent these...
متن کاملglobal results on some nonlinear partial differential equations for direct and inverse problems
در این رساله به بررسی رفتار جواب های رده ای از معادلات دیفرانسیل با مشتقات جزیی در دامنه های کراندار می پردازیم . این معادلات به فرم نیم-خطی و غیر خطی برای مسایل مستقیم و معکوس مورد مطالعه قرار می گیرند . به ویژه، تاثیر شرایط مختلف فیزیکی را در مساله، نظیر وجود موانع و منابع، پراکندگی و چسبندگی در معادلات موج و گرما بررسی می کنیم و به دنبال شرایطی می گردیم که متضمن وجود سراسری یا عدم وجود سراسر...

15 صفحه اولStudy on time-frequency extractors for partial discharge pulse current used in sequence grouping and identification
This paper introduces a general way to make feature extraction for partial discharge (PD) pulse waveshape used in sequence grouping resorting with equivalent time-frequency method. A digital ac PD pulse detection system with bandwidth of 10 kHz 40 MHz and sampling rate of 100 MS/s is introduced, which was developed to study those feature extractors. Simulation and test results with gas insulate...
