GE’s Advanced Methods for Non-Intrusive Inspection
Advisory for Method Selection
GE provides assistance in method selection. Depending on the asset, the component to assess and the type of defect to detect, one or more complementary methods of non-intrusive inspections could be recommended.
The selection of methods will take into account the application, the criticality, the history and events occurred. If the inspection requires the use of several advanced non-intrusive methods, they can be performed during the same short planned outage when mandatory.
Expert Diagnosis
In case of defect, the diagnosis can be generated remotely in a few hours by the GE expert. High quality measurement and data generated provides conclusive results which are compared to models created to evaluate the acceptable limits. Those models are developed by GE matter experts from R&D and manufacturing, this expertise in diagnosis is built on 125 years of experience in high voltage equipment engineering.
Maintenance Recommendation
As part of the service, GE provides a comprehensive inspection report including the results, the diagnosis, the expected remaining lifetime of the devices, and a detailed recommendation to plan the necessary maintenance or replacement actions.
Advanced non-intrusive inspection enables deployment of Asset Performance Management (APM) on a fleet of circuit breakers.

Digital X - Ray
Internal component image is printed on a flexible plate and runs through a high resolution (~40µm) laser scanner which reads and digitizes the film. The digital X-ray image produced is viewed and enhanced using powerful image processing software. Contrast, brightness, filtration and zoom can be customized.
Default Detection
Digital X-Ray inspection is suitable to evaluate the condition of aluminum, porcelain or polymer main, arcing and moving components. The defects that can be detected include:
Dynamic Contact Resistance Measurement
Dynamic Contact Resistance Measurement (DCRM) is conducted by injecting a Direct Current through the breaker. The voltage drop is measured when the breaker operates a close-open cycle at rated speed. The acquisition unit then calculates the resistance value. During a phase of the motion, arcing contacts are the only parts which touch, the condition of these contacts can be assess.
Default Detection
The comparison between the pattern reference and the measurement curve supports the condition of the arcing contacts and the breaker chamber moving parts assessment. Any change in dynamic/frictional characteristics of the circuit breaker immediately reflects as a change in the dynamic resistance signature.
DCRM fingerprint deviation indicates various defects including:
Vibration Monitoring
Any mechanical movement in equipment produces sounds and/or vibrations. The resulting signals are propagated to the external structure via various parts of the mechanism and through the interrupting medium. The accelerometers positioned on the external structure of the circuit breaker measure the vibration bursts. As the vibration fingerprints is highly repeatable for a healthy circuit-breaker, a change in dynamic/frictional characteristics immediately reflects a change in the vibration pattern and thus highlights a defect.
Mechanical Fault Detection
The main characteristic of vibration diagnostics is the detection of a change between a vibration fingerprints recorded during operation and the reference.
Typical problems indicated by deviation in the vibration pattern include:
Ultra High Frequency (UHF) Analysis
The monitoring of the Gas-Insulated Substation (GIS) insulation health through measurement of partial discharge is the most efficient and competitive solution to prevent potential high repair cost and long downtime.
Principal
Partial discharge is the source of electromagnetic waves in the range of ultra high frequency from 300 to 2000MHz. The signal goes along the GIS and is easily captured by the antenna. Both UHF internal or external sensors can be installed on any type of GIS up to 800kV. The system can monitor SF6 and g³ filled equipment. The frequency spectrum and time analysis of the UHF signal assist supervision of commissioning, operation and maintenance.
The pattern shape supports accurate identification of default type including:
