'Gas lighting' is not a phrase I'm familiar with. But I have NOT 'just said' that anyone is WRONG... I have backed my opinions up with the reasons why I believe them to be wrong. I have even referred to definitions used by the IEC and ITE and referred them to a web blog which explains my...
Let me put it this way. The 'potential difference' (voltage) across an AA cell is 1.5 V. Period! The 'potential' of the positive terminal, RELATIVE TO THE NEGATIVE TERMINAL, is +1.5 V. The 'potential' of the negative terminal, RELATIVE TO THE POSITIVE TERMINAL, is -1.5 V. Better still, let's...
Bulancore... Well, I could refer you to the IEC (International Electrotechnical Commission) definitions, in which 'line voltage' is defined as 'the voltage between two line conductors'.
Spot on!
Bulancore... Well, I could refer you to the IEC (International Electrotechnical Commission) definitions, in which 'line voltage' is defined as 'the voltage between two line conductors', and where 'phase-to-phase voltage' is described as 'deprecated'? Or to the UK's BS 7671 'Electrical Wiring...
Sophiecentaur, 'Voltage' is NOT measured 'relative to something'. Voltage is absolute. You are confusing 'potential' with voltage. Voltage is simply another word for 'potential difference', not 'potential'. Potential is always expressed as being 'with respect to' some fixed reference point...
Unfortunately, the Wikipedia article contradicts itself with its terminology. I would simply argue that the term 'line voltage' defines the voltage between any pair of the three supply conductors and, therefore, 'line voltage' describes the voltage between any pair of LINES (i.e. 'line voltage'...
I have heard electricians saying that 'Ohm's Law is universal', 'energy is delivered to a load by electrons', 'work and heat are forms of energy', and numerous other misconceptions. Are you suggesting that, because a concept is widely misunderstood, it should not be challenged? Regarding the...
I absolutely agree that these terms DO exist, particularly in the field. But they simply don't make sense and those who wish to learn about three-phase circuits would be better off if they learned to use the correct terminology. And as this is a science/engineering site, doesn't it also make...
In order to work on high-voltage equipment, that equipment must be (1) de-energised, (2) isolated from any live circuits, (3) earthed (grounded) on both sides of the equipment to be worked on, (4) protected by some form of barrier with notices indicating danger of high voltage, and (5) a 'permit...
No, the three conductors are called 'lines'. The 'phases' are the three windings of a generator or transformer and the three loads which are connected in wye or delta. Which is why you CANNOT measure a 'phase to phase' voltage -it simply doesn't exist. See article on this subject...
If you examine a three-phase line diagram, delta or wye, it should be obvious that while you can measure the voltage across phase (phase voltage), you cannot measure a 'phase to phase' voltage. The expression, 'phase to phase' is widely used but completely incorrect... the correct expression is...
