Passage of High-frequency Signals through Power Transformers
We consider the possibility of passing high-frequency signals past power transformers forming part of an electrical grid. We first model a transformer, including its laminated core, to obtain asymptotic behaviour of currents and voltages in the secondary circuit. Having got this we are able to determine the effects of different by-pass mechanisms which might be tried to get the high-frequency s...

متن کاملPiezoelectric transformers for a high power module
Abstract Piezoelectric transformers are mainly commercialized for a LCD back light inverter module. With regard to laptop computers, the required output power for a piezoelectric transformer is around 5 W at present, and higher power will be needed for wider displays in the near future. In addition, modules such as AC-DC adaptors or fluorescent lamps may require a higher output power of more th...
متن کاملSuitability of Ultra High Frequency Partial Discharge Measurement for Quality Assurance and Testing of Power Transformers
Well known reasons for local failures in power transformers are caused by partial discharges (PD) in the electric insulation. Continuous deterioration over time increases the defect which finally can lead to a breakdown of the entire insulation. The importance of PD measurement is accommodated by standardized electrical measurement according to IEC 60270 [1] which is required for acceptance cer...
متن کاملAn Intelligent Sensor for the Ultra-High-Frequency Partial Discharge Online Monitoring of Power Transformers
Ultra-high-frequency (UHF) partial discharge (PD) online monitoring is an effective way to inspect potential faults and insulation defects in power transformers. The construction of UHF PD online monitoring system is a challenge because of the high-frequency and wide-frequency band of the UHF PD signal. This paper presents a novel, intelligent sensor for UHF PD online monitoring based on a new ...
