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 Distance between neutral and groun pin in plug is not same?
The distance between the neutral and ground pins in a plug is not the same to prevent accidental short circuits or contact between the neutral and ground wires. This helps to ensure safety by reducing the risk of electrical shocks or fires. Additionally, it helps maintain the proper functioning of electrical circuits by preventing interference between the neutral and ground connections.
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.
If the loads were only 240v on a single phase 240v system with a center tapped transformer the neutral conductor would carry?
If the loads are balanced, the neutral conductor in a single-phase 240V system with a center-tapped transformer would carry no current, as the currents flowing in opposite directions would cancel each other out. If the loads are unbalanced, the neutral conductor would carry the difference in currents between the two lines.
Should the neutral in a service panel be connected to a system ground electrode?
No, the neutral (white wire) should be connected to the center tap of the supply transformer. The electrical service that comes to your home should have 3 wires. Across the 2 black wires should be 240 VAC. That comes from a transformer that steps down from the transmission voltage that is on the high voltage lines. The "center tap" of the output of that transformer gives you 2 legs of the supply, each at 120 VAC. In years past, the center tap has often been connected to ground, but that is no longer the case. The center tap is the neutral connection, and the ground is the part that keeps you from being electrocuted.
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.
When a neutral electrical charge comes in contact with another neutral electrical charge what happens?
When two neutral electrical charges come in contact, there is no transfer of electrons between them. They will remain neutral and there will be no repulsion or attraction between them.
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 neutral earthing and body earthing of transformer?
Neutral earthing refers to the practice of connecting the neutral point of a transformer or electrical system to the ground, providing a reference point for the system voltage and enhancing safety by preventing overvoltages. Body earthing, on the other hand, involves connecting the metallic body of the transformer or electrical equipment to the ground to protect against electrical shock and ensure safety in case of insulation failure. Both methods are essential for maintaining system stability and ensuring the safety of personnel and equipment.
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.)
Should there be voltage between the neutral and ground?
No, ideally there should be no voltage between the neutral and ground wires in an electrical system.
How do you install earthing neutral for transformer in transformer room?
you shouldn't do it yourself, get an electrician.
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.
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 neutral earth compensator?
For earth fault protection on the windings of a delta connected transformer. Used in MV distribution. An earth fault current return path is provided by connecting a Neutral Earthing Compensator (NEC) between the three phases of the power system and the earth system. This is done at the source of the supply. The NEC transformer winding has a Zig-zag configuration with no secondary winding. The impedance of the winding is high when there is no fault on the system resulting in only a small magnetising current in the transformer windings. The Zig-zag winding configuration results in a low impedance when an earth fault condition occurs. By inserting resistance between the neutral of the Zig-zag transformer and earth, the earth fault currents can be limited to any desired value. The resistance value and rating has been standardised to allow an earth fault current of 300 amp for 10 seconds, although some older installations may still operate at the old standard of 600 amps.
