The IMPM-1V01 intelligent protection and measurement device integrates protection, control, monitoring, measurement, and recording. It adopts a large capacity and resource redundancy design, with a plug-in and plug-in structure, suitable for the protection, control, measurement, and monitoring of various voltage levels of power systems. It can be configured for various distribution feeders, transformers, capacitors, incoming/bus tie backup automatic switching, motors, and other protections. Users can choose different models according to their on-site needs and apply them to different objects. They can be used for different main wiring methods, such as single bus, double bus, and multi bus wiring. The protection function also supports different types of power grids, such as neutral ungrounded systems, arc suppression coil grounded systems, and low resistance grounded systems. In addition, IMPM-1V10 can store 4 sets of protection settings, and the group switching function enables it to quickly and conveniently adapt to multiple operating modes. IRIG-B time synchronization, event reporting, waveform capture, reduce fault diagnosis time, and lower maintenance costs. IMPM-1V01 supports RS485 bus and Ethernet communication network forms to meet the communication and network structure requirements of different users, industrial sites, network environments, and systems of different scales. And it supports dual network mode, working in parallel or as a hot standby mode. This further improves the reliability of communication. Communication with upper layer devices can be achieved using Modbus RTU, Modbus TCP, IEC60870-5-103, and Profibus DP protocols.
