FDSL024RD is a type of current differential protection which works on the principle of measuring the amount of current flow in a transmission line. The device uses the principle of measuring the phase difference between two values of current, which in this case is referred to as the primary current and the secondary current. The primary current is the normal line current while the secondary current is usually sourced from either the short-circuit current or the zero-sequence current. The current differential protection works by measuring the phase difference between these two values of current to detect any abnormal behavior on the transmission line. If an abnormal current is detected, then the protection will activate and trip the transmission line.

The current differential protection is mainly used for the protection of long distance transmission lines. It is especially effective for transmission lines that are prone to having large currents due to the high load on them. This protection is very important in order to prevent any damages to the transmission line as well as the facility equipment connected to it. The current differential protection also has a wide application field, as it can be used in power plants, substations, transmission networks, and distribution networks.

The principle of current differential protection is based on the fact that the maximum amount of current that can be transmitted through a transmission line is limited. Therefore, when the primary current is greater than the secondary current, then it indicates a possible overcurrent condition on the line. Once this overcurrent condition is detected, then the protection will activate and trip the transmission line. The current differential protection also works on the principle of detecting any phase shifts or phase differences between the two currents, which can indicate any abnormal behavior on the transmission line. This protection can be used for both AC and DC systems.

The current differential protection can be used to provide protection against overcurrents, phases shifts, and other types of abnormal behaviors that could lead to damages on the transmission line. The protection is also highly reliable and can detect any abnormal behaviors very quickly and accurately. This protection is very effective in minimizing any possible damages to the transmission line as well as the connected facility equipment. The current differential protection is a must have for any facility that uses long distance transmission lines, as it can help ensure the safety and reliability of the facility.
