This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: For future smart grid infrastructures, utilizing the capabilities of recently introduced wide band gap (WBG) devices can significantly reduce the weight, volume and maturation cost of power electronic applications. However, the presence of these devices in the power network will introduce a new electrical constraint in the form of repetitive fast rising square voltage waveforms characterized by high repetition rate. These waveforms might influence the discharge mechanism of insulation system of power equipment in a way, different than AC. Under such circumstances, it becomes necessary to investigate the reliability of power conversion equipment of the future transmission network such as medium frequency transformer (MFT). For high power application, the insulation system of MFT is expected to incorporate dielectric liquid as its primary insulation medium. However, the discharge mechanism of dielectric liquid under fast repetitive square voltage is not very clear today. Therefore, this thesis aims to investigate the partial discharge (PD) mechanism under square voltage waveform to address power electronic applications like MFT. For this, the specifications of a test bench are defined and developed during this thesis to reproduce the electrical stresses in the form of a fast rising unipolar square voltage and switching frequencies above 50 Hz. As the PD measurement under fast rising square voltages is difficult due to electromagnetic interferences caused by high speed switching, the PD detection by optical detection is chosen, which detects the photons emitted during discharge events. To achieve the goal, in the first step the optical detection technique is validated under AC 50 Hz by comparing it to the standard electrical measurement. Then, PD measurements are performed under square voltage waveforms and the results are compared to the AC excitations to understand the impact of non-sinusoidal stress. This work presents the development of a test bench which can generate unipolar square voltage (USV) waveforms with dV/dt between 10-100 kV/μs at 20 kV. It demonstrated optical sensor as a decent partial discharge indicator under high dV/dt. Further, the test bench is assessed to measure partial discharges under varying USV parameters such as changing rise times, repetition rates and duty cycles.

Download or read book Simulation and Modelling of Electrical Insulation Weaknesses in Electrical Equipment written by Ricardo Albarracín Sánchez and published by BoD – Books on Demand. This book was released on 2018-10-17 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Around 80% of electrical consumption in an industrialised society is used by machinery and electrical drives. Therefore, it is key to have reliable grids that feed these electrical assets. Consequently, it is necessary to carry out pre-commissioning tests of their insulation systems and, in some cases, to implement an online condition monitoring and trending analysis of key variables, such as partial discharges and temperature, among others. Because the tests carried out for analysing the dielectric behaviour of insulation systems are commonly standardised, it is of interest to have tools that simulate the real behaviour of those and their weaknesses to prevent electrical breakdowns. The aim of this book is to provide the reader with models for electrical insulation systems diagnosis.

Book excerpt: The sensitivity and calibration of partial-discharge detection systems is an important aspect of the general subject of partial-discharge measurements of products or structures involving electrical insulating materials. The primary objective is to perform a measurement, using a detection system having a sensitivity adequate to the purposes of the test, in the presence of inevitable electrical noise. Of equal importance is the matter of calibration which requires that fairly-accurate information be obtained as to the magnitudes of the changes that take place in the insulation system when it is stressed at some particular voltage.
