Schneider SEP363 Digital Protection Relay

• Rich protection functions: Equipped with phase current short-circuit protection, which can be set with definite time delays and multiple standard inverse time curves, capable of dealing with different types of overcurrent faults. The ground protection function is similar to phase current protection, with corresponding setting values and optional curves. It also has functions such as transformer power-on stability protection, negative sequence unbalance protection, and equipment overload protection, providing all-round protection for power equipment.
• Temperature monitoring function: Can work with the MET148-2 temperature sensing module to detect the temperature of 8 devices, and can monitor the internal temperature of equipment such as transformers, motors, or generators in real-time. The preset temperature range for alarm and trip is 0 to 180℃, which helps prevent equipment failures caused by excessive temperature.
• Display and communication functions: Equipped with an advanced user-machine interface with a display resolution of 128×64 pixels, which can clearly display various operating parameters and fault information. It supports communication protocols such as Modbus RTU, facilitating data interaction with other devices or systems to realize remote monitoring and management.
• Flexible setting of parameters: The setting values and delays of various protection functions can be set according to the actual needs of the power system, which can adapt to different operating scenarios and protection requirements.

• Power substations: Can be used for the protection of various electrical equipment in substations, such as transformers and transmission lines, to ensure the reliable operation of substations and the normal distribution and transmission of electricity.
• Industrial fields: Suitable for various industrial enterprises, protecting equipment such as motors and frequency converters in factories, preventing production interruptions caused by electrical faults, and improving the continuity and stability of industrial production.
• Commercial and civil buildings: In large commercial buildings, office buildings, hospitals and other places, it can ensure the safety of their power distribution systems, provide reliable power protection for lighting, air conditioning, elevators and other equipment, ensure stable power supply in the buildings, and meet people’s daily needs.
• Infrastructure: Can be applied to transportation infrastructure such as airports, railway stations, and subway stations, as well as municipal infrastructure such as water supply and gas supply, to safeguard the power systems of these important places and ensure the normal operation of infrastructure.
