Core Technologies | TRIPOD Corporation

TRIPOD assesses equipment condition using Electrical Signature Analysis (ESA), vibration analysis, oil and grease analysis, and video-based vibration visualization. We combine the findings to investigate anomaly signatures and their possible causes.

Conceptual comparison of equipment diagnostics with medical examinations and a deterioration trend over time.

Electrical Signature Analysis (ESA)

ESA analyzes current and voltage from operating motors and generators to assess electrical and mechanical anomalies, including those in connected machinery. It originated in nuclear power plant valve research at Oak Ridge National Laboratory (ORNL) in the 1980s. The technology was licensed to Framatome (Nuclear Parts Center), which developed an industrial diagnostic platform. MotorDoc extended its use to wind turbines in the 2000s.

How It Works

Source: Framatome / Nuclear Parts Center, EMPATH™

We collect current and voltage at the control panel during operation and analyze their frequency components. We compare the results with equipment structure and operating conditions to assess motors, generators and connected pumps or fans. Measurement points, connections and applicability are checked for each installation.

EMPATH™

“Walkaround” Model

Framatome’s portable system assesses equipment condition using three-phase current and voltage.

EMPATH CMS™

Continuous Monitoring Model

Framatome’s permanent monitoring system acquires and analyzes data at configured intervals to track changes in equipment condition.

E-Plug™

Permanent Install

Framatome’s measurement connection module enables signal acquisition without opening the cabinet door after initial installation.

EMPOWER™

MCSA Diagnostic Model

MotorDoc’s compact instrument assesses equipment condition through MCSA using single-phase current.

Wind Turbine Applications

We combine current and voltage analysis with wind-condition and SCADA data to assess drivetrain health from the blades through to the generator. Where the required signals are available at the tower-base control panel, measurement can reduce the need for tower climbs.

EMPATH™ completes data acquisition and automated preliminary analysis within 60 seconds. This excludes connection setup, engineer-led analysis for the final assessment, and reporting.

Vibration Analysis

We assess imbalance, misalignment, resonance and loose mountings from vibration levels and frequency components. We compare these findings with ESA results to investigate possible causes.

Tribology Diagnostics

Tribology concerns friction, wear and lubrication. We analyze oil and grease for bearing and gearbox wear, contamination and lubricant degradation, and compare the findings with ESA and vibration results.

Motion Amplification (MA Camera)

Motion Amplification makes small movements in video visible. It helps identify where equipment moves and investigate resonance, looseness and vibration transmission. TRIPOD provides this diagnostic service with partner companies.

Data Analysis & Consulting Services

We listen to your challenges regarding equipment condition monitoring and maintenance, providing support for data analysis and operational improvements. We also offer diagnostic equipment implementation and paid training courses for ESA.

Maintenance cycle showing monitoring and prediction, diagnostics and risk assessment, failure analysis, and repair and replacement.

Research & Academic Collaboration

We actively engage in academic and applied research on ESA and machinery condition monitoring technologies.

ESA application research for generators and wind turbines
Development of diagnostic methods for low-speed and multi-pole machines

We promote joint research, academic publication, and technology dissemination through industry-academia collaboration.

We guide you to the optimal diagnostic methods for your target equipment.

Please provide details regarding your equipment type, ratings, operating conditions, and any specific symptoms of concern. We will verify the applicability of ESA and, if necessary, propose an integrated diagnostic approach combining vibration analysis and lubricant testing.
