What is neutral break?
Electricity is transmitted to the consumer via line cables. Neutral conductor (neutral) is a conductor used in the power grid to return current from the consumer to the generating station.
Neutral break is a break that occurs in the conductor used to discharge an unequal load in the phases to the neutral position and automatically balance the system.
What is neutral in a power line and what does it do?
Electricity is transmitted to the consumer via line cables. Neutral conductor (neutral) is used in the power grid to return current from the consumer to the generating station. In normal condition, it acts as neutral protection and has no voltage.
Electricity is transmitted from the generating station to the consumer via a three-phase network. It consists of three conductors with operating voltage, as well as neutral and ground conductors. A pair of working conductors has a voltage of 380V between them, called linear. The working conductor and zero in a pair have a phase voltage of 220V.
With the help of the neutral, self-regulation of the load in a three-phase network also occurs. With an unequal load on the phases, excess current is discharged to the neutral position and the system is automatically balanced. ENERJİTEM
Why does neutral break occur?
The main reasons for the neutral to break are;
Faults occurring in power networks
Unbalanced load distribution
Wiring without adhering to the necessary rules.
Old or faulty electrical installation of living spaces 'apartment etc.'
Oxidation that occurs in electrical transmission lines over time.
Mechanical damage (Damage to electrical transmission lines, etc.)
Lack of maintenance of power grids
can be listed as.
What are the neutral break protection methods?
It is necessary to install a voltage relay to protect against neutral breakage.
