Loss of neutral can be caused by several ways. Some of the most common causes are: Weather – bad weather such as storms and lightning can cause power problems. Accidents – unpredictable accidents such as a tree falling on the wires can result in loss of neutral.
Full Answer
What is a loss of neutral in a circuit?
Loss of neutral is a serious condition. A break in the neutral conductor will simply result in a loss of the energy supply which leads to an Irrespective of load balance. Loss of neutral can be caused by several ways. Some of the most common causes are: Weather – bad weather such as storms and lightning can cause power problems.
What happens to the current when the neutral is disconnected?
This means that currents entering the star point of a three phase load must either sum to the current leaving or they must sum to zero. Now if you disconnect the neutral no current can leave the star point of the load so the currents entering must sum to zero.
What causes a power line to lose neutral?
Loss of neutral can be caused by several ways. Some of the most common causes are: Weather – bad weather such as storms and lightning can cause power problems. Accidents – unpredictable accidents such as a tree falling on the wires can result in loss of neutral.
What happens if you have a loose neutral in a transformer?
This all goes to show how a loose neutral combined with other faults can be a serious issue. If you lose the power company neutral the current has no way to return to the transformer. If you are the only one on the transformer then you should experience this.
What happens if you lose a neutral wire?
If the neutral wire is broken or disconnected, the out of balanced current cannot return to the supply through the star point, but it must return. So, this current takes the path back to the supply through the lines.

What is a dropped neutral?
A broken neutral wire is when a neutral wire, which carries power back to its source, is disrupted. This means that the power inside the building becomes too high which can lead to serious problems. Happening from weather to accidents, a broken neutral wire can lead to electrical fires or electrocution if not resolved.
What causes a loss of neutral?
What causes Loss of Neutral. Loss of neutral can be caused by several ways. Some of the most common causes are: Weather – bad weather such as storms and lightning can cause power problems. Accidents – unpredictable accidents such as a tree falling on the wires can result in loss of neutral.
What is a broken neutral?
A broken neutral is relatively common but potentially life-threatening electrical fault that can affect households and businesses. Power flows in and out of your premises from a distribution network, entering via the active cable and leaving via the neutral cable.
Why is my electrical appliance damaged?
Any electronic appliance connected to the wiring will most likely be damaged due to overheating. If there are problems with the neutral line, electricity may travel through a different path. This may be via water pipes, stoves and metal taps or any other conductor of electricity.
Is it expensive to replace electronic equipment?
Replacing valuable electronic equipment can be very expensive. Loss of neutral is a serious condition. A break in the neutral conductor will simply result in a loss of the energy supply which leads to an Irrespective of load balance.
Can copper wires be stolen?
Stolen copper wires – While there is blackout there is no electricity running through wires, this is an easy opportunity for copper wires to be stolen and sold for money. Overhead wires – Overhead wires are not only easily damaged, but they are also easily accessible to be stolen.
What does "open neutral" mean?
open neutral means somewhere there is a white wire not connected or has a loose connection. even under the house could be additional junction boxes to look for. Share. Improve this answer.
How to test continuity of a line?
To test continuity of the lines you do not need power, just a voltimeter tool so you can shut off the circuit. Starting at the first outlet, set your voltimeter to a low Resistance setting and test the neutral from the lead to the ground wire. You should get a near zero reading meaning No Resistance.

But the earth rod and the transformer ground are not going to carry enough current to stabilize the load. Loss of neutral between the house and the service will result in the potential between the two hots and neutral varying depending on the total load on each side. So it will be divided just like it is now but not always equally.

Transformers are usually grounded. Houses still have 3 wires. 2 hots and a grounded neutral.

I was replying to the poster that said he had never seen a transformer ground and asked if houses have 4 wires now. Did I say the service entrance neutral did not carry a load? No, I didn't.
Why are my portable heaters brown?
The wattage of the portable space heaters isn't really enough to give you the brown power that you are experiencing (provided that the incoming lines are the proper gauge for the load/run). Low voltage will also not cause the flickering lights that you see - they should just dim (as if controlled by a dimmer). Even the satellite receivers shouldn't be that affected by low voltage (the main circuits are behind a transformer - rectifier setup) and even with the low voltage, would probably remain in regulation.#N#I don't believe that your problem has been discovered yet.

What Causes Loss of Neutral
Where Is Loss of Neutral Common
- Many African countries are a victim of loss of neutral, especially South Africa. South Africa are currently suffering from rolling blackouts. An app which provides schedules, alerts and forecasts for power outages, has become the most popular downloaded app in SA. Eskom, the state power monopoly, is struggling to generate enough electricity to meet needs, and has re-introduced a by…
Effects of Loss of Neutral
- In the event of loss of neutral, the single-phase voltage will rise to the three-phase level subjecting your equipment to >400V instead of 230V. This results in over voltage and can be catastrophic for your appliance. Any electronic appliance connected to the wiring will most likely be damaged due to overheating. If there are problems with the neutral line, electricity may travel through a differe…
Solution to Loss of Neutral
- To protect against loss of neutral, the Sollatek AVS30can protect against temporary over voltage of 400V (TOV400). It will also protect against high and low voltage, brown-outs, power back surges and voltage dips. The AVS30 will disconnect the power when it’s bad and reconnect automatically on return of normal power which protects against short- and long-term damage to …
