Alstom MPM123 Measurement & Protection Module – MiCOM Grid Automation Series
When a critical measurement or protection module fails in a substation or power distribution network, the consequences extend far beyond a single tripped breaker. Without a functioning MPM123, protection relay systems lose their ability to accurately measure electrical parameters and execute protective actions — exposing transformers, busbars, and downstream equipment to fault currents, overvoltage events, and cascading failures. Every minute of unplanned downtime in a high-voltage environment carries significant operational and financial risk.
The Alstom MPM123 is a dedicated Measurement and Protection Module engineered for integration within Alstom’s MiCOM grid automation platform. Positioned as a core functional card within the MiCOM relay family, the MPM123 handles real-time acquisition of electrical quantities and feeds protection algorithms that safeguard transmission and distribution infrastructure worldwide. Its deployment spans utilities, industrial power plants, and renewable energy substations across Europe, Asia, and the Middle East — making it one of the most widely referenced protection modules in the global grid automation market.

Frequently Asked Questions
Q: Is the Alstom MPM123 still in production?
A: Alstom’s grid automation business has transitioned to GE Grid Solutions (now GE Vernova). The MPM123 may be available as a spare part through authorized channels or the secondary market. Contact us to check current stock availability.
Q: Can the MPM123 be used as a direct replacement in an existing MiCOM relay?
A: In most cases, yes — provided the host relay chassis and firmware revision are compatible. We recommend confirming the relay model and hardware revision before ordering.
Q: Do you provide a warranty on refurbished MPM123 modules?
A: Yes. Refurbished units carry a 90-day functional warranty. Terms are confirmed in the sales quotation.
Q: What is the typical lead time for the MPM123?
A: Lead time depends on stock availability. In-stock units ship within 3–5 business days. Sourced units typically require 7–21 business days. We will confirm at the time of quotation.
Q: Can you supply multiple units for a substation retrofit project?
A: Yes. We regularly supply bulk quantities for utility and EPC project requirements. Volume pricing is available — please include your project quantity in your inquiry.
