Protection relays and systems serve as an important safety measure for power systems against disruptive elements, such as short circuits, overloads, and other out-of-bounds scenarios. Designed to detect these anomalies and immediately shut down the electrical system before they can cause any unwanted results, these protective systems form a vital part of any power grid. In this article, we’ll discuss the SE-107 application field and working principle in detail.The SE-107 is a type of magnetic field based protection relay, designed to provide robust and sensitive protection against overloads, short circuits, long delays, and other types of anomalies in power systems. It’s actively used in many large-sized industries with high-level safety requirements, such as process plants, power plants, foundries, steel mills, paper mills, petro-chemical plants, and more. The device is manufactured to meet various standards for industrial safety and system performance.The SE-107 works on the basis of magnetic field protection. Essentially, the system senses any disruptions in the magnetic field that may be caused by overloads, shorts, or other anomalies. It then sends a signal to shut down power to the affected part of the system, preventing the occurrence of any harm. The working principle behind this principle is relatively simple: the system is equipped with two electro-magnetic sensors that measure the current and voltage draw from a circuit. When any problem is detected, the system’s logic analyzes the data and then creates an alarm signal.The device is equipped with a wide range of parameters that can be adjusted to suit the user’s environment, and the typical setting is typically sufficient in most cases. For example, the SE-107 can be programmed to detect a specific range of short circuits, or mismatches in current and voltage, while also allowing for protection against long delays and other possibilities. Additionally, the device includes a “trip delay” setting that can be adjusted to delay the alarm signal for up to 3 seconds. This allows the device to be used in high-load environments, where fast shutdowns may cause more damage than good.The SE-107 also includes a wide range of features that make it a great choice for users. For instance, it can be easily integrated with existing systems, and it enjoys a notably long service life of up to 10 years, making it a wise investment that will pay off in the long run. Furthermore, it’s equipped with a “self-tuning” feature that allows the system to be quickly reconfigured to meet any changes in current or voltage measurements, making the device incredibly easy to use and maintain.In conclusion, the SE-107 magnetic field protection relay is a reliable and robust system designed to provide safe and reliable protection in a variety of power systems. Its ease of integration, high performance, long service life, and host of configurable features make it an ideal choice for any safety-critical applications.
