Description
The ALSTOM N895313512X N95313012D SUP-AL N895313000R is a highly specialized and critical electronic printed circuit board (PCB) assembly from Alstom’s (now part of GE Grid Solutions or Hitachi Energy) protection and control systems, most likely for their MICOM or Px40 series of protective relays or associated equipment. This board functions as a core processing, power supply, or dedicated interface module, essential for the relay’s protective functions, communication, or analog signal processing.
Product Description
The ALSTOM N895313512X N95313012D SUP-AL N895313000R is a complex, multi-function printed circuit board that forms the operational heart or a vital subsystem within a larger protective relay unit. Its precise role—be it as the main CPU board, a power supply module, or a specific I/O interface—is defined by its intricate circuitry and component layout. Integrating the ALSTOM N895313512X N95313012D SUP-AL N895313000R as a replacement is a targeted repair procedure to restore a high-value protection device to full operational status. This assembly is responsible for executing protection algorithms, managing communication protocols, or conditioning critical analog signals from current and voltage transformers. For protection engineers and maintenance specialists, sourcing the ALSTOM N895313512X N95313012D SUP-AL N895313000R is a precise and cost-effective strategy to avoid replacing an entire relay. The reliability of the protection scheme depends entirely on the flawless operation of this internal component. The design and manufacturing of the ALSTOM N895313512X N95313012D SUP-AL N895313000R adhere to stringent standards for electromagnetic compatibility and long-term stability in utility substation environments.
Product Parameters
-
Manufacturer: Alstom (legacy brand, now part of GE Grid Solutions or Hitachi Energy depending on product line and timeframe).
-
Product Family: Likely associated with MICOM (e.g., Px40, Px30) or Alstom protective relay series.
-
Model: The string N895313512X N95313012D SUP-AL N895313000R represents a comprehensive part number, potentially including the main PCB code (N895313512X), a sub-assembly or variant code (N95313012D), a functional designation (SUP-AL possibly indicating a Supply or Auxiliary module), and a related reference number (N895313000R).
-
Function: Internal PCB Assembly – Specific function must be determined from relay manuals, but options include: Power Supply Board, Main Processor Board, or Communication Interface Board.
-
Compatibility: Designed exclusively for a specific relay model and hardware version (e.g., a MICOM P443 relay). It is not interchangeable across different relay types.
Advantages and Features
-
OEM-Level Repair: Enables a component-level repair of a sophisticated protective relay, preserving the original housing, wiring, and often the calibrated measurement circuits, at a fraction of the cost of a new unit.
-
Preservation of Configuration: When replacing a non-volatile board (like a power supply or I/O board), the relay’s core settings and configuration stored elsewhere may be retained, minimizing re-commissioning effort.
-
Genuine Performance Guarantee: As an original Alstom component, the ALSTOM N895313512X N95313012D SUP-AL N895313000R ensures the relay will perform exactly to its original certified specifications, maintaining all protection curves and safety ratings.
-
Extended Asset Lifecycle: Supports sustainable maintenance practices by allowing critical grid protection assets to be repaired and kept in service for decades.
-
Precision Engineering: Contains specialized components and firmware tailored for high-accuracy, high-reliability protection applications in the electrical power industry.
Application Cases in Industry
-
Electrical Transmission & Distribution Substations: Used within feeder protection relays (e.g., MICOM Px40 series) protecting overhead lines and cables from overcurrent, earth faults, and distance faults.
-
Industrial Power Distribution: Protecting incoming utility feeds and large motor circuits in heavy industry such as metals, mining, and data centers.
-
Renewable Energy Plants: Serving as a critical component in protective relays for solar inverter stations or wind farm collection systems.
-
Railway Electrification: Protecting traction power supply systems and catenary networks.
Comparison with Competing Products
Competing protection relays from Siemens (SIPROTEC), SEL (SEL-700), and ABB (REF) have their own proprietary internal boards with zero cross-compatibility. The ALSTOM N895313512X N95313012D SUP-AL N895313000R is unique to its specific Alstom relay model. Its advantage is that it is the only component that will restore the relay to its original, type-tested condition. Compared to a complete relay replacement, this spare part strategy maintains consistency across an existing fleet of relays, uses existing panel cutouts and wiring, and requires no change to protection settings philosophy or operator training.
Selection Suggestions and Precautions
-
Absolute Part Number Verification: This is a critical step. You must physically verify the exact part number printed on the failed board and match it character-for-character with the ALSTOM N895313512X N95313012D SUP-AL N895313000R. Even minor discrepancies indicate a different board with a different function.
-
Identify the Host Relay Model: Determine the exact relay model (e.g., MICOM P442, P443) and hardware version from the front plate. Cross-reference the board part number with the relay’s technical manual or parts list to confirm compatibility.
-
Firmware and Configuration Management: Determine if the new board requires firmware to be loaded or if settings need to be transferred. Always back up the relay’s complete configuration file before starting the replacement. The new board may be blank.
-
High-Voltage Safety & Procedure: Replacement must be performed by qualified personnel following strict electrical safety rules (Lock-Out Tag-Out). The entire relay and associated circuits must be fully de-energized and isolated.
-
Source from Specialized Suppliers: Given its complexity and criticality, procure the ALSTOM N895313512X N95313012D SUP-AL N895313000R only from highly reputable suppliers specializing in legacy Alstom/GE/Hitachi protection equipment. Confirm they offer testing guarantees and can provide technical documentation linking the part to your relay model.
