    Phase Shift Circuit

    Thank you for your help. I have now decided to avoid using power electronics, so I guess that a phase shifting transformer is the only way to proceed!

    Phase Shift Circuit

    Is there any way to use power electronics to do this? Or is a phase-shift transformer the only way to do it?! Thanks

    Phase Shift Circuit

    Hello, I would like to know if there is any way of applying a phase shift to a 50Hz AC voltage. I know that it is done on circuit board using op-amps, but is there any way of doing this at a high power level, say phase-shifting the 220V single phase AC voltage to a 20kVA load. Thanks

    1-phase Power from a 3-phase generator

    Thank you kindly for your help. I guess I should consider a means of starting the pumps so that I can limit the starting currents. Let us say that I am running my three phase generator to supply an unbalanced 3-phase load. Will this damage my generator in the long run? Will it trip any of the...

    1-phase Power from a 3-phase generator

    Hello, thank you for your contribution! My single phase load is several small single phase appliances plus 3 3kVA single phase pumps. I have tried to balance these loads equally among the three phases but the generator keeps tripping! Is this tripping avoidable? Is it a negative sequence...

    1-phase Power from a 3-phase generator

    Hello, I have a 22kVA generator that is feeding a 3-phase 3kVA compressor. That means that there is 19kVA of leftover power. I wish to use this 19kVA to supply a single phase load. What is the best way to do this? Do I use a rectifier to convert three phase to Dc and then use an inverter to...

    SVC or STATCOM

    Hello again. Which FACTS technology is cheaper, SVC or STATCOM? Does the answer to this question depend on MVA size? Thanks

    Why Synchronous Generators

    Has anyone any other suggestions?

    Why Synchronous Generators

    Thank you for your help. This was one of the reasons that I had in mind. What about efficiency? Fault-ride through capability? Dynamic Stability? Cost?

    Why Synchronous Generators

    Hello, I have a decent idea what the answer is but here is my question: Why do large scale power generators (hydro, oil, coal, gas) use synchronous generators and not asynchronous (induction) generators? Thanks

    IEC Flickermeter 61000-4-15

    Where is this old matlab program that you mentioned? I would greatly appreciate it if you could tell me where it is or send it to me.

    IEC Flickermeter 61000-4-15

    Hello, I am looking for a MATLAB/SIMULINK implementation of the IEc Flickermeter according to IEC 61000-4-15. Please help, Thanks.
