🎉We can now proudly present the winners of the TAPAS Community Challenge 2018! 🎉
Congratulations to Team "Wireless Charging" (idea 56). We are really excited for all finalists and a really big thank you to all participants for your interest in this challenge!

We got over 200 submissions! 65 ideas got one or more TAPAS boards, 10 submissions were presentation-ready.
And now we have 5 finalists! YEAH 😃 The finalist's idea numbers were 40, 56, 68, 212 and 213.
What's next?
We are now preparing the next steps for you, the community. Please stay tuned!
We are working on a forum and a separate webpage. If you have any question please don't hesitate to contact us via email!

High quality sinewave three-phase large-power inverter for dielectric tests, temperature rise tests and power tests on MV and HV apparatus

Working in a power testing laboratory, performing type tests on medium voltage and high voltage equipment (such as power transformers, instrument transformers, medium voltage circuit breakers and switchgears, high voltage disconnectors, insulators, etc.) requires readiness of the laboratory equipment and the human operators. Actually we perform the tests using classic electrical equipment like power transformers, changing ratio manually, and controlling manually all the electrical parameters like voltage, frequency. We wish to implement a general purpose yet specialized power inverter to achieve the same results with a lot less effort, increasing productivity and earnings for the laboratory. The result of the inverter implementation can be shared with SIEMENS factories to improve their factory acceptance tests capability also. In attachment you can find a scale simulation of an asymmetric power fault current achieved through Arduino Uno board using PWM modulation and a totem-pole inverter using a couple of complementary NPN and PNP BJTs.

    Due to the fact we have at least three different ideas in this post (dielectric tests 50/60 Hz, temperature rise high current 50/60 Hz and very high power short time withstand current tests) and we are five engineers working on it, do you think is possible to receive at least three TAPAS boards?

    Hello Davide,
    thanks for your additional comment.
    We will provide three boards for you and your team.
    The email with further instructions will be sent to you shortly.
    Have a nice day :-)

    Hi Davide,

    how is it going? Do you need any help regarding the realization of your project?
    Here is just a friendly reminder that submission deadline for your presentation is on 24th of June. :-)
    We are really excited to see your progress! 
    Please post the progress within your idea board submission.

    PS: We want to do a community call with you! Please use our doodle to find a date which fits best for you. :-)

    Hey Davide,

    Please keep in mind that the submission deadline for your presentation is on 24th of June! We are already looking forward to seeing how you brought the TAPAS board to life! :-) Remember that you still have time to work on the implementation of your idea after the submission!

    Please upload your presentation and everything you want to share with us in your idea board entry.

    Good luck :-)

    Jacqueline @ TAPAS Team
