Solving the Discontinued Hardware Crisis

The GE MTM-120(S-A20-120VA) is a metering module commonly integrated into GE Multilin protection and control platforms, as well as broader GE Power Management relay systems deployed across utilities, substations, industrial plants, and heavy manufacturing facilities. These platforms were engineered for 20–30 year operational lifespans, and many remain in active service today — long after GE ceased production of the associated hardware.

The core problem facing plant engineers and maintenance managers is straightforward: the control architecture is deeply embedded, the re-engineering cost is prohibitive, and the OEM no longer supports the hardware. A single failed metering module can take a protection relay offline, triggering either an unplanned outage or a forced bypass of protection logic — both of which carry serious operational and safety consequences.

Condition & Reliability Assurance

Sourcing obsolete hardware from secondary markets carries real risk. DriveKNMS applies a structured 5-step QA process to every discontinued module before it is offered for sale or shipped to a customer:

• Step 1 – Visual & Physical Inspection: Full external inspection for mechanical damage, label integrity, and connector condition. Pins are examined for corrosion, oxidation, and deformation.
• Step 2 – Electrolytic Capacitor Assessment: Aging electrolytic capacitors are a primary failure mode in legacy electronics. Each unit is assessed for capacitor bulging, leakage, and ESR deviation.
• Step 3 – Firmware & Revision Verification: Where applicable, firmware version and hardware revision are documented and cross-referenced against known compatibility matrices for the target platform.
• Step 4 – Functional Bench Test: Units are powered and tested under controlled conditions to verify basic operational integrity prior to shipment.
• Step 5 – Packaging & ESD Protection: All units are packaged in anti-static materials with desiccant to prevent moisture ingress during international transit.
