Thank you all for the valuable input you have provided. The reason for my question VE1BLL is that after a few decades as an Engineer, I have decided to try my hand at teaching. I soon discovered as LiteYear indicated, that the physiological effect of current was a complex topic that ought to...
If your finger was to come into contact with a ‘live’ 240 volt 50 Hz conductor in a wiring installation with earthed neutral (assume you have dry unbroken skin, rubber-soled boots standing on a wooden floor) – it would hurt!
It would seem from my calculations that taking into account the...
True – the percentage regulation is heavily dependent on the load power factor. Whereas the load for the short-circuit test for percentage impedance is unity. So the %Reg and %Z would be different if the load was not unity.
During the short-circuit test for finding the percentage impedance...
With regard to calculating load sharing when paralleling transformers, and calculating short-circuit fault currents, how similar is Percentage Voltage Regulation (given with respect to full-load voltage) to Percentage Impedance?
I know how both quantities can be found by experiment/calculation...
I need to explain to a class how a blow-out coil works. I have a basic understanding of it (eg. coil energised by load I, two pole plates, arc attracted to it), but I need a more detailed description or clear picture showing how it works.
