What is an error current?

also known as short -circuit current, and fault current is a term used to describe the situation in which the flow of current passing through the electrical circuit is not within the normal range. This type of abnormal or unusual current flow can be caused by a number of different problems, including a short -circuit of an electrical device or some defect that adversely affects the current path, causing the output to be somewhat low. When the current flow falls outside the normal range, the device that is designed to prevent short -circuits will not respond correctly, causing to correct the situation as quickly as possible.

The process of localization of fault current will vary slightly depending on the overall design of the connected wiring system. With a simple system, it is sometimes possible to identify the origin of the problem by creating the simple conductor of the wires that make up the system. In more complex systems where cabling is closed and canRunning extremely for a long distance, it is usually necessary to use a device that actually monitors and measures the flow of current from the point of origin to the end point. One examples of this type of device is the time domain reflector, which emits a pulse that triggers the length of the cabling and a pulse registers in the vlava. Pulses derived from pulsation allow a good idea of ​​where the obstacle or defect is, accelerates the repair of the wiring and eliminate the fault current.

fault current repair is very important not only for the ongoing operation of the electrical system, but also for the safety of those who live and work around this system. The abnormal current flows can lead to power overvoltage that damage the device that is powered by the current of the supplied connection, or may charge devices so that when they touch, the electric shock is given. Depending on the nature of the fault current and the amount of voltage involved, this shock may be enough to cause death.

all over the world exIte different standards to define what is an irregular or failure current. Different countries have stipulated regulations that require the installation of circuit breakers and other guarantees that help minimize the potential danger associated with short -circuit. It is not uncommon for standards that apply to both residential and commercial settings, which must be implemented by safety measures that are relevant to the amount of current, which is usually supplied in any case.
