Could a bad neutral in the line between the transformer and the electrical meter effect the meter readings?

Yes there is that possibility but if there was any problem with the neutral you would see it manifest itself in the lights in the house. Problems with dimming and flickering. If you suspect a fault in the meter call the power authority and have them check it out. They shouldn't charge you for the service and because they bill you from the readings of the meter they will want to know one way or another.

Why live and neutral wire essential for proper working of electrical circuit?
Two wires are always needed to supply electrical equipment so that the current has a complete circuit to flow in. One of the wires is earthed at the supply transformer, that one is called the neutral, and the other one is the live.
Why does your electrical outlet read 80 volts instead of 120 volts?
It could be a faulty transformer, a fault in insulation in the wiring, or improper grounding. If you read 80 volts between hot and 'ground', but 120 volts between hot and neutral, then it's most likely a grounding issue.
What is role of neutral in three phase system?
In a three phase system, connected wye, neutral is the common return, and it is grounded. In a delta connection, there is no neutral.
How do you reduce neutral to earth voltage in three phase system?
It is done by connecting the neutral to earth at the transformer that produces the three-phase supply. If the three phase wire supply equal currents, there is no current in the neutral wire and its whole length stays at earth potential, but if there is current in the neutral it produces a small voltage on the neutral at places away from the transformer.
What is the meaning of the DC electrical terms Positive Neutral and Negative?
DC means "direct current." Normally this is provided by a battery or transformer. Positive - The positive contact where current flows into a circuit. Neutral - The ground wire in case something happens like a surge. Negative - The negative contact where current leaves.
Does an electrical panel get bonded after a step down transformer?
Yes, both to provide a new neutral-bond connection and to equalize potential between various bonds.
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.
Do all electrical power sources flow to earth e.g. Secondary winding of an isolating transformer with no earth connection on the neutral line?
There are situations where the secondary of a transformer is not grounded and the neutral is not connected to the neutral of the primary. This can cause a potential shock hazard so the secondary side needs to be protected.
What is the power line voltage between phase and earthing?
It is the same as phase to neutral. As the neutral is earthed at the electricity suppliers transformer.
What is the difference between an isolation transformer and distribution transformer?
in isolation transformer earthing is not provide on secondary side but in ordinary transformer neutral of secondary side is earthedAnswerAn isolation transformer is a 1:1 ratio transformer; its function is to electrically isolate the secondary side from the primary side without changing the voltage. An example of an isolation transformer is the one used in a shaver socket.A distribution transformer is a step-down transformer, used within the electricity network's distribution system. An example of distribution transformer is a pole-mounted transformer, supplying low voltage to residences.(Of course, all mutual transformers provide electrical isolation between primary and secondary.)
Why live and neutral wire essential for proper working of electrical circuit?

How do you install earthing neutral for transformer in transformer room?
you shouldn't do it yourself, get an electrician.
You can use neutral to autotransformer?
Yes, but the transformer must have both the hot and neutral to work as designed. A auto-transformer is not a variable resistor that could reduce current/voltage by a change in the resistance which could be used in the hot and or neutral wire. An auto-transformer is designed to have the hot wire and neutral on each end of the winding with a variable tap in between. The resistance of the transformer and the inductance will effect the circuit to a limited way if placed in the neutral but this effect will not vary the voltage over the full range, the amount of voltage reduction will vary with the load's current draw, see ohms law. Neither a resistor or a auto-transformer connected in the neutral line only will increase the voltage above the level of the input like a correctly connected auto-transformer . Stanley

What is the reason for using a neutral current transformer on a transformer?
A current transformer is primarily used at the neutral point of a transformer for earth fault protection. A neutral current transformer will measure any ground fault current which will essentially flow from the star point of the transformer. A fault-detection device other devices is connected to the current transformer and, if the fault current exceeds a certain trigger value, the fault-detection device will give a trip command to an earth-fault relay to disconnect the supply of electricity to the transformer.
How To Test An 230vac -230vac Isolation Transformer?
Make sure there is no voltage measured between line of secondary and neutral of primary. I.e. neutral of primary and secondary are not connected by any means.
