Electric Field Simulations and Analysis for High Voltage High Power Medium Frequency Transformer
The electronic power transformer (EPT) raises concerns for its notable size and volume reduction compared with traditional line frequency transformers. Medium frequency transformers (MFTs) are important components in high voltage and high power energy conversion systems such as EPTs. High voltage and high power make the reliable insulation design of MFT more difficult. In this paper, the influe...
متن کاملHigh Frequency Characteristics of Medium Voltage XLPE Power Cables
The response of a cable can be used to analyze the variation of the material characteristics along its length. For diagnosis of possible ageing, it is necessary to know how cable design, material properties and cable insulation ageing affects the wave propagation. A cable model has therefore been worked out based upon the high frequency properties of the cable insulation and conductor systems. ...
متن کاملPower Frequency Inverters for High Voltage Tests
The essential demand in high AC voltage testing is the availability of a test voltage with high quality, which is variable in amplitude and frequency. The power supply should not have any influence on the measurements – even the PDmeasurement and should be able to control a fault of the test objects insulation safely. These demands can be fulfilled using modern IGBT inverters. Two level voltage...
متن کاملCoreless Transformer for Power Quality Measurement at Medium Voltage Level
Original scientific paper Measurement of grid voltage harmonic components is an important part of power quality measurements. Current high voltage transformers with iron core are not linear and cannot easily be used for accurate measurement of "polluted" voltages in wide frequency range. In this paper, design details of a new coreless voltage transformer for power quality measurement are given....
متن کاملA modular power electronic transformer for medium voltage application
In this paper a modular power electronic transformer (PET) for feeding critical loads is presented. The PE based transformer is a multi-port converter that can connect to medium voltage levels on the primary side. Bidirectional power flow is provided to the each module. The presented structure consists of three stages: an input stage, an isolation stage, and an output stage. The input current i...
