Generator Inspection & Electrical Testing

The TDS Mechanical Services Team Disassembles Generators, Inspects Mechanical Components, and Reassembles the Generators. Our Specialists Conduct Assessments of Generators, Electrical Systems, Windings, Support Structures, and High-Voltage Testing.

Inspection & Testing

TDS Disassembles and Inspects Generator Components, Including the Starter, Field, and Excitation System. After Testing, We Realign and Reassemble the Unit to Ensure Operational Readiness.

Advanced Electrical Testing

We Perform Megger and HiPot Tests to Assess Insulation Health and Stress Limits. Advanced Diagnostic Flux Probes and Rolling Impedance Help Identify Field Faults and Speed-Related Issues.

Winding & Insulation

Our Engineers Evaluate Winding Supports, Detect EMF Damage, and Address Core Looseness. We Follow Proper Repair Procedures for All Stator Insulation Types, Including Air, Hydrogen, and Water-Cooled Systems.

Generator Testing Details:
