On a standard three prong AC outlet what should the AC voltage measure between neutral and ground?
Zero, or very close to it. If there is a large neutral current flowing, voltage drop on the neutral leg could cause a volt or so to read between the two. If you read full line voltage, the outlet is wired wrong!
Why we measure voltage between neutral to earth?
To ensure that it complies with the relevant electrical wiring regulations.
How do you determine hot to neutral?
How do you determine what? If you are asking how do you measure the voltage between Hot and Neutral, I suggest a voltmeter. If you are asking how do you differentiate between Hot and Neutral in home wiring, the Hot is Black and Neutral is White.
What is the problem if I measure voltage on an 120vac outlet 96 volts from neutral to ground?
Firstly measure the voltage between your live and earth.Assuming you get ~120 volts here, the problem is a loose neutral somewhere along the line.If you get 24volts the problem is a bad earth connection, with a fault voltage on it.TBH it's most likely the former, as the latter implies 2 separate faults.
Why do you read no voltage if one leg is still hot when you measure lead to lead?
You don't provide enough information to be certain what you are measuring. If you have a hot leg then by definition you will have a voltage between the hot leg and ground or neutral (if neutral bonded properly to ground in main panel). However, there may be no voltage between hot and some unspecified "floating" wire.
Voltage across Neutral and earth for a 3 phase auto transformer?
A grounded neutral will be at earth potential. A floating neutral will be at a voltage dependent upon the voltage imbalance between phases, and the design of the transformer.
Could a neutral wire be powered?
There should be zero voltage between neutral and ground.
What is voltage between earth and line?
In a typical residential situation there is 220 to 240 volts between the two hot wires that are typically red and black and 110 to 120 volts between neutral and either black or red. The voltage between neutral and earth should be zero.
Why would you get half voltage between live and neutral?
You can measure a small voltage between earth and neutral, even if the neutral is grounded to earth, because the neutral conductor acts as an antenna picking up electromagnetic radiation in the atmosphere. -------------------------- If the above answer were true, the earth conductor would also act as an antenna. But the real answer is, if you read ANY voltage between the neutral and earth, the neutral is broken somewhere between where you are measuring and the panel or not properly bonded in the panel. Call a competent electrician to repair the problem.
Should there be power from common to ground in wall socket?
120 volt wall outlets. Their could me a small voltage between neutral and ground,up to around 1.5 volts. What you are measuring is the voltage drop on the system at that point in the system. You see the neutral and the ground are at the same level some where up stream (service panel). The neutral is under the same load as the phase conductor, and the neutral will drop voltage same as the phase. This is in fact the way I measure voltage drop, (neutral to ground.) However don't get fooled by high imped. meter, They have a way of ghosting a voltage. Or floating high, You get a reading but the voltage is really not their.
Why is three phase voltage 400 V when single phase is 230 single phase 1.73 3 phase. what is 1.73?
I will try and make this as simplified as possible. The secondary side of transfomers are connected in star - which means there is a neutral / earth connection. If you measure between a LINE to LINE ('line voltage') voltage you will measure 400V, but now we have introduced the neutral / earth and we measure between LINE to NEUTRAL ('phase voltage) 's LINE to EARTH we will get 230 V. The reason for this is that, because the phase voltages are displaced, in time, by 120 electrical degrees, you must add them vectorially to obtain the line voltage. And the vectorial sum of two 230-V phase voltages, displaced by 120 degrees, is 400 V -or 1.732 times either of the phase voltages.
What is the standard voltage of a laptop charger?
the voltage of a laptop charger is in between fifteen to twenty four voltage.
