Transformer Oil Testing Lab

Service Overview

A Transformer Oil Testing Lab is a specialized facility that evaluates the quality, purity, and performance of insulating oil used in electrical transformers and related equipment. Transformer oil serves as both an insulating and cooling medium, and its condition directly affects the reliability and lifespan of the transformer. Regular testing helps detect moisture, oxidation, contamination, and dielectric breakdown, ensuring the transformer operates safely, efficiently, and without unexpected failures. The testing process follows international standards such as IEC, ASTM, and IS, providing accurate diagnostics for preventive maintenance and performance optimization.

Our Process

1

Sample Collection

Collect transformer oil samples in clean, moisture-free containers following standard procedures (IS 9434).

2

Visual Inspection

Check for clarity, color, and presence of sediments or suspended particles.

3

Testing Phase

Perform tests such as: BDV, Moisture Content (ppm), Acidity (mg KOH/g), DGA, Resistivity and Tan Delta

4

Data Analysis & Interpretation

Compare results with standard values and past trends.

5

Report Generation

Issue certified test reports with recommendations for maintenance or oil replacement.
