Transformer Testing & Preventive Maintenance

Dissolved Gas Analysis (DGA), Insulation Resistance, & Oil Filtration

Protect utility and industrial substation transformers from catastrophic faults. Our testing technicians carry out diagnostic sweeps, execute oil sampling, measure winding ratios, and perform online filtration loops to scrub carbon and moisture from dielectric fluids.

Core Capabilities

Insulation Power Factor testing and turns-ratio verification (TTR).

Dissolved Gas Analysis (DGA) for tracking internal arc indicators.

Transformer oil filtration, dehydration, and degassing.

Winding resistance and sweep frequency response analysis (SFRA).

Architecture Summary

Diagnostic instruments sweep frequency responses and analyze fluid compositions, comparing baseline curves to detect winding displacement or insulation deterioration before faults trigger.
