Solid State Transformers: New Approach and New Opportunity Shilpakala
The advancement in semiconductor technology has provided a new alternative to the hundred year old conventional transformer technology by providing an elegant solution using Solid State Transformer (SST). The SST is applied semiconductor technology for changing the voltage ratio. The SST can achieve high power density as well as operation at high frequency, thus reducing the size and the cost. ...
متن کاملImplementation of a Model-based Diagnosis System for Power Transformers
A Matlab/Simulink implementation of a model-based diagnoses system for power transformers based on structured residuals is presented in this work. Process models for thermal behavior and moisture diffusion in paper are observers for transformer temperatures and relative water concentration in oil respectively. An experimental setup consisting of a medium voltage distribution transformer equippe...
متن کاملFuzzy Logic Expert System for Optimum Maintenance of Power Transformers
Condition monitoring of power transformers improves the reliability and the safety of an electrical power network. It protects the transformers from failures, and avoids huge revenue loss to utilities and customers. The health status of transformers is decided by several influencing factors. An accurate health assessment of transformers has been a challenging task for the researchers as well as...
متن کاملDiagnostic Measurements for Power Transformers
With the increasing age of the primary equipment of the electrical grids there exists also an increasing need to know its internal condition. For this purpose, offand online diagnostic methods and systems for power transformers have been developed in recent years. Online monitoring is used continuously during operation and offers possibilities to record the relevant stresses which can affect th...
متن کاملSolid-state Power Switches for Hpm Modulators
Power modulators for pulsed microwave applications, generally utilizing a thyratron-switched PFN, typically produce 50-120 kV, 1-2 kA microsecond timescale pulses with sub-microsecond ( -100-200 nsec) risetimes. This paper will review an investigation into the feasibility of utilizing certain solid-state power switches at the relatively fast speeds required for HPM modulators. Two very differen...
