Protection System

Wiring Rele

Reliability and the ability of a power system to serve the consumer depends on the protection system used. Therefore, in design an electric power system, should be considered interference conditions that may occur in the system, through the analysis of interference.

power system protection is the protection system mounted on the electrical equipment of a power system, such as generators, transformers, and other tissues, the abnormal conditions of operation of the system itself.

Abnormal conditions it may be, among others: short circuit, over voltage, over load, low-frequency systems, asynchronous and others. (for details see the article: "Reliability and Power Quality")

In other words, the protection system is useful for:

1.  avoid or to reduce the damage to the equipment due to disturbances (abnormal conditions of operation system). The faster reaction protection devices are used, the less the influence of disturbance to the possibility of damage to equipment.
2. quickly localize the area have been affected, as small as possible.
3. can provide electrical services with high reliability to customers and the quality of the electricity.
4. securing people against the dangers posed by electricity.

Knowledge of currents arising from different types of interference on a site is very essential for the effective operation of the protection system. If an interruption in the system, the operator who feel the disorder is expected to soon be able to operate circuit-circuit Breaker right to remove the compromised system or a separate power of the affected tissue. It is very difficult for an operator to monitor disturbances that may occur and to determine which CB operated to isolate the interference manually.
