do a continuity test between the neutral and the metal enclosure of the equipment containing the neutral. infinity reading [ open line ] indicates floating neutral. Steve sorensen jr

How do you avoid floating neutral?
The neutral of a generator should never get into a condition where is is floating. All generators have the neutral tied to the frame of the generator set. It comes this way from the manufacturer. If it is floating then someone has disconnected the neutral wire from the frame. Just reconnect the neutral to the generator frame again to stop it from floating. Larger generators should also have a ground rod connected to the generator frame for grounding purposes.
Why floating neutral in a three phase supply is undesirable?
Floating neutral in 3 phase supply is undesirable as if the same thing occurs then there will be bad effect for all single phase equipment which we are using as phase to neutral voltage will exceed from its normal value and it will harm the equipments.
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.
What does the term floating neutral mean?
This could mean a couple of different things. At some point in the power distribution system, the neutral bus is normally tied to the ground bus. If the neutral is not grounded, this could be called a floating neutral. More often, the term is used to describe a load, such as a light fixture or motor where the neutral wire has accidentally not been connected. The hot wire is live, but the device does not function. The neutral wire normally provides the return path for current to flow. This is a very dangerous situation. The live voltage flows from the hot wire, through the load, then into the neutral wire. If the neutral is not connected (grounded), it becomes hot! Everyone knows the hot wire can bite you, but we normally expect the neutral to be dead. We may carelessly handle the neutral, thinking it is dead, but if it is floating (unconnected), it could be live. Many people have been killed in this fashion. As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
Can a 3 wire system create neutral voltages due to Harmonic distortion?
Yes, a 3 wire system can create neutral voltages due to harmonic distortion. Neutral voltages can also be caused by load imbalance between the two hots. It is normal for neutral to have a voltage differential relative to ground. Neutral is, after all, a current carrying conductor. In a well balanced system, however, there is little (theoretically zero) current in neutral.
What does floating neutral mean on a generator?
It means the neutral is not grounded.
What is a floating neutral wire?
a loose connection of a neutral wire

How to correct floating voltages in system neutral?
Floating means there's no reference to ground, so to fix this you supply a reference to ground (be it corner grounding, solidly grounding, high resistance grounding, etc.)

What can happen if a utility-sized electrical generator has an ungrounded neutral?
What you need to define is the statement "utility- sized electrical generator". It depends on what the generators output is used for as to the way it is internally wired. In some configurations there is no neutral to ground as in a Delta configuration.If the generator is configured for a Wye output and the neutral centre tap is not grounded there will be a floating voltage between the generator and the utility system ground. It is for this reason that the generator's neutral point is grounded to bring the floating voltage down to zero volts to ground.
Is orange the neutral wire in a plug?
No, the colour white is used to identify the neutral in electrical distribution systems.

How do you identify neutral and ground or earth wire means if someone has changed the terminals of wire then how will we identify which one is neutral and which one is earth?
mee too in the same situation. anyone help us out pl.
A body is just floating in a liquid. if the body is pressed down and and released what will happen?
If a body is floating IN a liquid, it has neutral buoyancy- does not go up or down. If it is floating ON a liquid, it has positive buoyancy. Neutral- when pressed down, body moves down- and when released, it stays there. Positive buoyancy- moves down, when released returns to it's position on top of the liquid.
What type of protection can you use to protect a 3 phase installation if the neutral becomes floating?
