VIRTUAL ELEX SHOW IET PRESENTATION

John Peckham
Good afternoon All


As the IET have not been able to do face to face Elex shows the organisers of the Elex shows have come up with the idea of a virtual Elex show. The IET are keen to contribute to the virtual show and are going to film a webinar using the same sort of format as the live shows.


Following the live show format the IET are going to present 2 topics. The chosen topics from the feedback from the live show audiences are PME earthing and bonding and EV charging.


So if you were in the live audience what questions would you like to ask? Post them on here and I will feed them back to the IET presenters to answer in the Q&A session?


The downside is no free bacon roll I am sorry to say!

    To include in your, educational talk to an remote audience:-

    Vehicle-to-home (V2H), Vehicle-to-building (V2B)  What would be the earthing arrangements.? Where would the inverter be?


    www.virta.global/vehicle-to-grid-v2g


    V2G stands for “vehicle-to-grid

    V2X means vehicle-to-everything.

    vehicle-to-home (V2H), vehicle-to-building (V2B)


    My experience of larger SCR rectifiers would be silicon after all a semi conductor and it has a standard volt drop across it in the forward direction of 0.6 volts, this of course means very little in electronics and can be catered for and even used for some old  meter protection by using diode back to back protection for the working mechanism that work below 0.6volts. But say 100 amps that is 100x.6 = 60 watts , so in this small example that is 60watts of heat to get rid of . So if they are pulling 300 or 400 amps from batteries back to the V2G then the cooling fans blowing air up through the heat sinks are going to keep you up all night. 


    Well anyhow at the moment President Biden Silicon Shortage Executive Order

    So all this future may not be in our time. But its interesting the way things are going.
