⚡ Transformer Testing Services
Transformers are the critical heart of transmission networks and industrial distribution infrastructure. Unexpected transformer downtime can stall factory production or plunge electrical grids into sudden blackouts, costing immense resources in emergency repairs.
Our advanced diagnostics laboratory delivers full-spectrum transformer testing designed to detect structural weaknesses, insulation decay, and winding faults early. We blend field-proven electrical measurements with sophisticated chemical fluid testing to provide absolute equipment health profiles.
🔬 Core Testing Methodologies
- Dielectric Strength & Insulation Profiling: Utilizing micro-ampere leakage detection to map the integrity of winding insulation layers and phase-to-phase spacing under high-voltage stresses.
- Winding Resistance & Turns Ratio Evaluation: High-precision low-resistance tracking across all tap-changer positions to detect localized hot spots or loose internal joints.
- Dissolved Gas Analysis (DGA): Advanced gas chromatography tracking of insulating oil to identify molecular ppm spikes in hydrogen, methane, or acetylene.
- Frequency Response Analysis (SFRA): Mechanical core footprint validation utilizing low-voltage swept frequencies to pinpoint winding shifts or coil geometry warping.
