FAQ
Q:How to select RTU Communication Panel？
A:How to choose a communication panel? Here are my personal opinions. It is advisable to select products from the same manufacturer for the communication panel, relay protection panels and the entire relay protection system of the power station, facilitating subsequent commissioning. Strictly follow technical documents, as specifications and configurations of communication panels vary by technical requirements. Blind selection may cause operational troubles in later use.
Q:What communication interfaces does the RTU communication panel support?
A: It is equipped with RS485, Ethernet and optical port, compatible with IEC60870-5-101, IEC60870-5-104 protocols to realize data interaction between field devices and master station.
Q: How does the RTU Communication Panel ensure stable data transmission under harsh on-site environment?
A: With optimized anti-electromagnetic interference design, it effectively resists substation field surge interference and guarantees continuous, error-free remote data uploading.
Q: What is an RTU Communication Panel?
A: It is a centralized cabinet integrating RTU main unit, switches, optical transceivers, power supply and terminal blocks. It converges field device signals and uniformly realizes data upload to the SCADA master station.
Q: Main functions of this panel
A: Concentrate telemetry/tele-signal/remote control data, realize redundant network communication, convert optical fiber and electrical signals, provide stable power distribution and signal isolation for all substation front-end acquisition equipment.
Q: Standard internal components
A: RTU module, industrial Ethernet switch, fiber media converter, DC power supply unit, lightning protection modules, terminal rows, air breakers, grounding busbar.
Q: Why configure dual-switch and dual-network redundancy?
A: If one network channel or switch fails, the other path automatically takes over transmission, avoiding total communication interruption and improving system reliability for unattended substations.
Q: Supported mainstream communication protocols
A: IEC 60870-5-101 / 104, Modbus RTU/TCP, DNP3, IEC 61850; it connects protection relays, measuring instruments and box transformer RTUs via RS485 and Ethernet.
Q: What transmission modes are available?
A: Optical fiber long-distance transmission, Ethernet wired networking, and optional 4G/5G wireless module for backup communication.
Q: Key wiring requirements
A: Signal cables use shielded wires with single-point grounding; power lines and weak current communication lines are routed separately; all secondary circuits are equipped with surge protection devices.
Q: Grounding rules for the whole panel
A: The cabinet shell, shielding layer and lightning protection module are connected to the station’s unified grounding grid to restrain electromagnetic interference and lightning surge damage.
Q: Master station displays all devices offline
A: Check panel input power, switch running status, fiber link and IP address parameter matching; confirm no loose terminal connections or broken optical cores.
Q: Individual device data cannot be uploaded
A: Inspect the corresponding serial port or network cable, verify device address and communication baud rate, and check whether the terminal wiring is loose or reversed.
Q: Frequently communication packet loss
A: Reinforce shielding grounding, separate strong and weak current wiring, replace aging optical modules or damaged network cables.
