    Voltage transformers and magnetic field leakage

    Thanks heaps, Jim! ... You've been extremely generous with your help! As for your anecdote, I found it extremely interesting (and most informative)! Wow! ... This forum is very lucky to have a guru like you around to help people!

    Voltage transformers and magnetic field leakage

    I reside in Australia, where the grid power supply is 240V @ 50Hz. As the user wants to operate a US device here in Australia, a 240V-to-110V stepdown voltage transformer is required. Of course, such a transformer leaves the 50Hz frequency unchanged, but this is not likely to be a problem as...

    Voltage transformers and magnetic field leakage

    The price of the 100VA unit is approximately 75% of that of the 250VA unit. Your suggestion is quite ingenious, but unfortunately it falls outside the user's budget (also, having to find space for two of the 100VA units on the user's desktop would likely be a big problem). If you had to guess...

    Voltage transformers and magnetic field leakage

    Firstly, let me say thank you to everyone for your excellent posts in this topic so far. I've just realized that the pricing for the magnetic shielding and Mu metal options would result in the user's stipulated upper limit on the spend for the toroidal stepdown transformer being exceeded...

    Voltage transformers and magnetic field leakage

    You're probably right, it's just that I always get a little 'paranoid' when stepdown voltage transformers are to be placed immediately alongside IT equipment (the user's preference, in this case).

    Voltage transformers and magnetic field leakage

    Absolutely! Thank you for that information, but if we were to compare the resultant magnetic field leakages for a 100VA toroidal stepdown transformer and a 250VA toroidal stepdown transformer, given the same power throughput, what would we likely observe? (i.e. in which of these two 'toroidal'...

    Voltage transformers and magnetic field leakage

    I’m looking to purchase a toroidal AUSTRALIA-to-US stepdown voltage transformer, and have narrowed my choice down to two models, one permitting a maximum rate of energy consumption of 100 Watts, and the other permitting a maximum rate of energy consumption of 250 Watts. Both of these maximum...
