Protection Relays & Systems: 1820DBX Application Field and Working Principle

The 1820DBX is a protection relay designed to help protect utility-grade reverse power relay systems by monitoring the amount of positive and negative power on the system. It is designed to help provide protection against reverse power flow in power systems and can help prevent costly damages from overloading. The 1820DBX is a single-phase integrated protection system that is compatible with any existing relaying system, and designed to help protect the auxiliary services and generators in the system.The 1820DBX’s application field includes single-phase generator systems, transformer systems, and single-circuit lines. Its application field is limited to two-wires single-phase systems. Additionally, this protection relay is designed for use in transformer protection, generator protection, and line protection circuits. The 1820DBX is typically used in systems of up to 30 kW of reverse power. This reverse power relay also features an adjustable manual/auto mode and can be remotely adjusted for optimization in low-power applications, or for greater protection in heavy-duty applications. The 1820DBX protection relay features a wide range of protective functions and also includes support for Auto Recloser control. The main features of the 1820DBX include protective functions such as Reverse Power Protection, Overload Protection, Directional Protection and Automatic Recloser Control. Additionally, the 1820DBX is equipped with sensitivity adjustment software, which allows the user to optimize the protection setting based on the application.The 1820DBX uses an AC power measuring circuit to sense the amount of power flowing in both directions through the system. This circuit helps to detect any imbalance in the amount of positive and negative power being used in the system. When an imbalance is detected, the protection relay triggers and shuts down the system to prevent any further damage. The 1820DBX includes a sensitivity adjustment feature, which allows the user to lower or raise the sensitivity of the protection relay based on the application. Additionally, the Auto Recloser control feature helps to limit the number of system shutdowns and reduces the overall downtime of the system.Overall, the 1820DBX protection relay is a reliable and effective option for reverse power protection systems. It is able to provide efficient protection against reverse power flow, overloading, and directional protection. The 1820DBX is an easy to use, reliable, and versatile system that can be used in a variety of applications, including single-phase generator systems, transformer systems, and single-circuit lines. It is also compatible with existing relaying systems and can be remotely adjusted for optimization in low-power applications, or for greater protection in heavy-duty applications.
