Detects early signs of insulation breakdown or overheating before major failures occur.
Ensures transformers operate safely under load with optimal performance.
Avoids costly failures and unplanned downtime through preventive maintenance.
Meets IS, IEC, and CEA requirements for periodic transformer testing.
Extends transformer life through timely maintenance and oil management.
Our state-of-the-art laboratory is equipped with the latest technology for precise mineral oil analysis and quality control.
Our in-house lab conducts a complete suite of tests in line with IS 335, IS 1866, IS 9434, IEC 60296, and ASTM D3487 standards.
Purpose: Measures dielectric strength to withstand high voltages without failure.
Benefit: Low BDV indicates presence of moisture or contamination.
Method: Karl Fischer Titration for accurate moisture measurement.
Impact: High moisture reduces insulation strength significantly.
Purpose: Detects gases indicating electrical faults, overheating, or arcing.
Interpretation: Each gas pattern corresponds to specific fault types.
Purpose: Measures acid content formed due to oil oxidation.
Impact: High acidity corrodes internal parts and accelerates aging.
Purpose: Assesses oil's resistance to current flow.
Result: Higher resistivity indicates better insulation properties.
Purpose: Indicates presence of polar contaminants in oil.
Analysis: Low IFT suggests oil deterioration.
