50Hz Vs. 60Hz - Page 2 - Electronic Circuits Projects Diagrams Free

so, 60Hz isnt for making a good time base. it was suggested by Tesla when he made the three phase power generation and transmission system. in the abscence of a standardization body different companies started making different types of generators depending on their ease. then AEG in germany made a system working at 50Hz because it somehow suited them and the others had to use their systems because they had a strong monopoly. and after the 2nd world war britain started using 50Hz AC systems. and then the whole world followed. but the americans took the word of tesla and used a 60Hz system. now, although a 50Hz system is less efficient in generation and transmission it is still more popular than 60Hz

i hope im right??????????????

I would have thought the differences between 50Hz and 60Hz are fairly minor, slightly larger transformers - that's about it!.

I also would suspect that the minor advantage of 60Hz is more than lost by the disadvantage of 110V rather than 230V?.

Does the Swiss tram or trolleybus sytem still use 33.3Hz?

As for 50Hz versus 60Hz there are minor advantages (and trade-offs) to both ...
higher frequencies will allow smaller inductive components (transformers)
lower frequencies will suffer less from line losses on long distribution runs (capacitance and inductance)
I don't think there is any magic behind either number - they had to pick a value to standardise to and these two have proliferated - maybe 400Hz would be more popular if shipbuilding were leading the technology at that time :?: :roll:

yeah but u can use 230V with 60Hz. and infact Nikola Tesla suggested the use of 230V (or maybe 240V) with 60Hz because according to his calculations that was the optimum combination.
