What is RCD Soket?

RCD Soket is a standard socket that includes an integral residual current device (RCD) that adds its standard ground failure functions. The RCD unit is an electrical device that prevents electric shock, fires and damage to the device automatically by reducing the power supply to the circuit if the imbalance between living and neutral wires is detected. Many industrial and domestic electrical installations include a central unit of RCD, which protects all outlets in the installation. The RCD socket is an extremely reasonable supplement to those who have no protection against ground failure outside fuses or individual circuit breakers. There are two basic types of RCD sockets: a solid type that is permanently mounted in the wall, and portable units that connect to unwilling outlets.

Electric abbreviations between living and neutral and living and countries are among the most common causes of fires, damage to equipment and often fatal shocks. Short circuit that does not start to disconnect the delivery of the delivery can causeSparking, extreme increase in local temperature and potential electrical flow. Properly evaluated circuit breakers and fuses generally do a good job to prevent these dangerous conditions, but are often not sensitive or fast enough. Negligence or lack of knowledge can also lead to the fact that fuses are overwhelmed with references that are too heavy, which often leads to catastrophic electric accidents. The installation of central RCD or RCD units can eliminate this danger by offering immediate short -circuit protection.

The

heart of the RCD socket is a hollow, circular, ferrite core through which live and neutral drawer wires pass through. The wound around the core walls is the wire coil that is connected to the electromagnetic sensor and mechanically connected to the main switch. The ferrite core and wire coil serve as a current transformer that maintains a secondary voltage below the sensor threshold if the current between ŽIt remains balanced and neutral. In the event of a short circuit, this current increases rapidly and increases the secondary voltage to the point where the sensor's threshold value exceeds, activates the mutual solenoid and turns off the power supply. All this happens in an incredibly short period of time, which effectively prevents spark, overheating and any chance of shock that could lead the heart of the victim into ventricular fibrillation.

The two most commonly based forms of RCD sockets are solid and drinking types. Fixed types are similar to conventional backups on the wall, while the RCD unit built into their cases. The portable type also has an internal RCD unit, but resembles an adapter with pins on its underside, which connects to an unprotected output and the same socket on the face of the unit. This allows user to add RCD protection to any socket at will. Both types usually have a test button that represents a controlled short circuit that allows you to test the unit before use.
