Advanced Motor Monitoring & Diagnostics

Integrated, cost effective monitoring and diagnostic features that leverage existing relay data without the need for additional devices or sensors to detect electrical, thermal or mechanical abnormalities before they become critical motor failures.

Electrical
Abnormalities

If undetected, insulation failure can evolve into phase or ground faults, causing equipment damage or loss, and significant unplanned downtime. The 869’s advanced motor monitoring and trending capabilities provide identification of critical electrical conditions.

Thermal
Abnormalities

The 869 continuously and proactively monitors the motor for Thermal Capacity Used (TCU) to provide early warning of thermal stresses.

Mechanical
Abnormalities

Without the need for additional sensors or probes, the 869 utilizes GE's patented Electrical Signature Analysis (ESA) / Motor Current Signature Analysis (MCSA) to identify mechanical abnormalities in the motor.
