3ASC25H214 DATX130
The 3ASC25H214 DATX130 simplifies transformer control with integrated tap changer automation, automatically adjusting voltage levels to maintain grid stability during load fluctuations. For example, in a renewable energy substation with intermittent solar or wind power, the module optimizes transformer tap positions to ensure consistent voltage supply to the grid. Its winding temperature monitoring feature uses thermal modeling to predict hotspots, triggering alarms before overheating occurs—a critical advantage in preventing transformer failures that could lead to widespread outages.
Engineered with secure boot and AES-128 encryption, the module complies with IEC 62443 cybersecurity standards, protecting against unauthorized access and data tampering in smart grid applications. The dual power supply inputs and hardened electronic design (surge protection up to 4 kV) ensure reliable operation in harsh environments, such as outdoor substations exposed to lightning or voltage spikes. The module’s self-diagnostic functions (e.g., watchdog timer, memory parity checks) reduce mean time to detect (MTTD) faults by 50%, enabling proactive maintenance and minimizing downtime.
The DATX130’s IEC 61850 compatibility enables seamless integration with ABB’s RELION® 600 series protection relays and Ventyx energy management systems, creating a unified platform for substation automation. In a modern utility substation, the module transmits real-time transformer data to a cloud-based analytics tool, allowing engineers to optimize asset utilization and schedule maintenance based on actual wear and tear rather than fixed intervals. This predictive approach reduces maintenance costs by 30% and extends transformer life by up to 10 years.
The ABB 3ASC25H214 DATX130 is indispensable in industries requiring precise transformer control and grid stability:
- Power Utilities: Manages power transformers in transmission and distribution substations, ensuring reliable voltage regulation for residential and commercial consumers. In a regional grid, the module coordinates tap changers across multiple transformers to balance load and reduce energy losses.
- Industrial Manufacturing: Monitors transformers in steel mills, chemical plants, and automotive factories, where stable power is critical for high-energy processes like welding or distillation. The module’s fast data update rate (<100 ms) enables real-time adjustment to sudden load changes from large motors.
- Renewable Energy: Supports transformer management in solar farms, wind parks, and microgrids, addressing the challenges of intermittent power generation. For a wind farm with variable wind speeds, the DATX130 optimizes transformer tap positions to maintain grid compliance and maximize energy export.
- Critical Infrastructure: Protects transformers in data centers, hospitals, and airports, where uninterrupted power is non-negotiable. The module’s redundant power supplies and cybersecurity features ensure reliable operation during power surges or cyber threats.

Pre-installation preparation: Mount the 3ASC25H214 DATX130 on a substation control panel or DIN rail, ensuring proper grounding and separation from high-voltage cables. Connect VT/CT signals using shielded twisted-pair wiring, and terminate power inputs with surge protection devices. Configure communication parameters (IP address, protocol, security settings) via ABB’s RELION® Configurer software, verifying connectivity with the substation’s IEC 61850 network.
Maintenance recommendations: Perform quarterly visual inspections of the module’s status LEDs and terminal connections, tightening any loose wires (torque: 2.5 N·m). Use ABB’s Transformer Health Monitor software monthly to analyze trends in winding temperature, tap changer operations, and load profiles. Annually, update firmware to incorporate new cybersecurity patches or feature enhancements, and test the module’s self-diagnostic functions to ensure reliability. In harsh environments (e.g., coastal substations), clean the module’s ventilation slots every six months to prevent corrosion from salt or dust.
