The ABB PPD113B01-25-111000 3BHE023784R2530 is a highly advanced, fully configured Feeder Protection and Control Relay from ABB’s flagship Relion® 670 series, specifically the RED670 model tailored for line differential protection applications. This device represents the pinnacle of protection technology for high-voltage and extra-high-voltage transmission lines, integrating comprehensive primary and backup protection, advanced automation, precise measurement, and extensive communication capabilities into a single, robust unit. The core function of this specific configuration is to provide ultra-fast and selective current differential protection (87L) for transmission lines, which works by comparing the current entering and leaving the protected line segment in real-time via high-speed communication channels (typically fiber optic). Any imbalance indicates an internal fault, triggering an instantaneous trip, typically within one cycle (20ms or less), to isolate the fault and maintain power system stability.
The suffix codes PPD113B01-25-111000detail its exact hardware configuration, indicating specific options such as current/voltage input ranges (e.g., 1A or 5A CT inputs, voltage inputs), binary I/O count, communication interfaces (including dual-redundant Ethernet ports for IEC 61850 and differential protection channels), and possibly integrated arc protection sensors. The part number 3BHE023784R2530is the unique order code. Beyond differential protection, the relay includes a full suite of backup functions: distance protection (21), directional/non-directional overcurrent and earth-fault protection, auto-reclosing (79), breaker failure protection (50BF), and power swing detection. For transmission system operators, this relay is a critical asset that ensures grid reliability, minimizes fault damage, enables adaptive grid automation, and provides deep diagnostic insights for condition-based maintenance.
ABB RED670 PPD113B01-25-111000 is distinguished by its unsurpassed speed and selectivity in primary protection. The current differential principle provides absolute «unit protection,» operating only for faults within its defined zone, eliminating the need for time grading with downstream devices. This enables tripping times of less than 20ms, which is critical for maintaining transient stability of the power grid, especially on critical transmission corridors. The support for redundant, high-availability communication channels for differential protection ensures system reliability even if one channel fails.

Multifunctional integration and grid support features are central to its value. It consolidates all necessary line protection, control (auto-reclosing, synchrocheck), and monitoring functions into one device, reducing panel space, wiring, and lifecycle costs. Advanced functions like adaptive auto-reclosing (single-/multi-phase, with dead time control) and power swing detection and blocking enhance grid resilience and prevent unnecessary trips. Native support for IEC 61850 (including GOOSE for fast interlocking and Sampled Values for process bus) makes it a cornerstone of the digital substation, enabling significant reductions in copper wiring and enhanced interoperability.
Superior diagnostic capabilities and user-centric design ensure operational excellence. The relay features comprehensive self-diagnostics and monitoring of its health, communication links, and CT/VT circuits. The powerful disturbance recorder with detailed pre- and post-fault waveforms and sequence of events (SOE) is invaluable for rapid fault analysis and root-cause determination. Configuration and maintenance are simplified through the intuitive local HMI and the powerful PCM600 engineering software. For asset managers, this relay not only provides the fastest possible protection but also delivers deep operational intelligence, enabling predictive maintenance strategies and seamless integration into modern grid management systems.
Application Areas
The ABB RED670 (PPD113B01-25-111000) is exclusively designed for the protection and control of high-voltage and extra-high-voltage transmission lines in utility and industrial power networks.
Its primary application is as the main and backup protection for two-terminal or multi-terminal transmission lines in voltage levels from 110 kV to 765 kV and above. This includes:
Transmission Grid Interconnectors and Backbone Lines: Protecting critical lines that transfer bulk power between regions, ensuring grid stability and reliability.
Renewable Energy Integration: Protecting lines connecting large-scale wind farms, solar PV plants, and other renewable generation facilities to the main grid.
Industrial Infeed Lines: Protecting dedicated high-voltage feeder lines supplying large industrial complexes (e.g., smelters, chemical plants, data centers).
Substation Configuration: Ideally suited for breaker-and-a-half, double-busbar, and other complex substation configurations where its multiple protection functions and extensive I/O handle complex bay control and breaker failure logic.
It is also applied in systems requiring phase comparison or current differential protection for short lines where distance protection may be challenged. Essentially, wherever fast, selective, and ultra-reliable line protection is paramount for grid security, the RED670 is the technology of choice.
