Engineering Scope & Capabilities
Substation Quality Assurance & Electrical Safety Audits
Electrical safety, power reliability, and regulatory compliance are essential for industrial operations. Trafo Engineering provides certified Quality Management and safety audits compliant with BNBC (Bangladesh National Building Code), IEEE, and IEC standards.
Scope of Quality Assurance Services
- Radiometric Infrared Thermography: Detecting micro-ohm contact deterioration, loose busbar bolts, and overheated CT/PT terminations under peak factory load.
- Secondary Current Injection Relay Testing: Verifying tripping curves of numerical overcurrent, earth fault, and differential relays using OMICRON / SVERKER test sets.
- Power Quality & Harmonic Analysis (IEEE 519): Identifying voltage sags, harmonics, and low power factor to eliminate utility penalties.
- Earth Grid Integrity & Step/Touch Potential: 4-point Wenner soil resistivity and earth pit resistance auditing.
Step-by-Step Engineering Methodology
Preliminary Substation Inspection & Thermal Scan
Non-invasive FLIR infrared survey across all breakers, busbars, and cable terminations.
Secondary Injection Relay Calibration
Testing numerical relay trip times at 2x, 5x, and 10x rated fault currents.
Power Quality & Earth Loop Logging
48-hour continuous power logging capturing voltage dips, swells, and THD.
Engineering QA Report & Action Plan
Issuing comprehensive audit dossier with color thermal images and prioritised fix list.
