Re: Transformer Hum

Having noted the enthusiasm for the Tesla Power Wall I did some research into high power conversion systems, basically inverters. The research paper I skimmed covered an AC-DC-AC Variable Speed Constant Frequency generator rated between 40KVA and 250KVA. What I noticed fairly quickly was the amount ...

Re: Transformer Hum

It may be worth noting that a transformer designed for use at 60Hz may have a smaller core than one designed for 50Hz*. Such a 60Hz transformer may well saturate on 50Hz with DC present. One reason commercial aircraft use 400Hz is to reduce the mass of transformer cores. *The difference will be smal...

HELP US SAVE AOS!!!

I want one, I need a small purse for loose change - but no price, so I have emailed them offering five bob as I have a couple halfcrowns in a draw here.
Very generous of you, I would only offer 2/6 as it would need a zip added to be of any use.

Re: (in)FAMOUS SLURPS

I recently saw an advert for an iPhone charging cable that cuts the time to fully charge the battery. I would love to know how this works because charge time is related to charge current and the only way to increase the charge current is to buy a more powerful charger.

Re: Eurovision song contest......!!!

If the UK stopped being a major sponsor of Eurovision we might not have to suffer the song contest.

Re: Upgraded fuses and car fires ?

It seems 50 odd cars have caught fire, presumably those had the bad fuses. As far as I know, those "thermal fuses" are not fuses as we know them. The heater module has coils to shunt power when anything other than the fast heater fan speed is selected. The thermal fuse is a spring loaded piece of m...
