PRS-7367 provides fast and selective protection, monitoring and control for feeders and capacitors. The relay can operate correctly over a wide frequency range in order to accommodate power system frequency variations during disturbances.
This relay can sample the analog values from the traditional instrument transformers, or receive the sampled values from the electronic current and voltage transformers (via a merging unit). The binary inputs and outputs of this relay can be configured according to the demands of a practical engineering through the PRS IED Studio configuration tool auxiliary software, which can meet some special requirements of protection and control functions.
This relay can fully support the IEC61850 communication protocol and GOOSE function, and can completely meet the demands of a modern digitalized substation.
The device integrates core protection functions such as non-directional/voltage-controlled directional phase overcurrent, ground overcurrent, over/under voltage, over/under frequency, and auto-reclosing. It supports multiple standard functional models including IEC 61850, IEC 60617, and ANSI, providing reliable security for feeders, capacitors, transformers, and other equipment.
Fully supports mainstream protocols such as IEC 61850 (including MMS, GOOSE, SCL), IEC 60870-5-103, DNP3.0, and ModBus, with multiple Ethernet ports (including PRP/HSR topologies), enabling seamless integration with station control, process, and SCADA systems.
Innovatively combines six functions—protection, measurement, control, remote signaling, merging unit, and remote module—into a single device, simplifying system architecture and enhancing overall reliability.
Built on a 32-bit high-performance dual-core processor, internal high-speed bus, and intelligent I/O ports. Its modular hardware design allows flexible configuration, strong interchangeability, and easy expansion and maintenance. Equipped with the powerful PRS IED Studio configuration software, it allows flexible setup of protection logic, setting groups, binary I/O, etc., meeting highly customized requirements.
Supports multiple GPS time synchronization methods, including SNTP, PPS, and IRIG-B, ensuring precise time-stamping for event records and system coordination under all conditions.
Features a high-resolution LCD display (HMI) and menu navigation keys for real-time monitoring of device status, event information, and measurements, as well as for modifying protection settings and configurations with ease. All functions are designed to be user-friendly.
