Chem-TechTM Laboratories is a leading provider for Transformer Oil analysis Services. Transformer oil is required to be checked for monitoring their insulating properties.
Testing of transformer oils is very essential, as Transformer oils are subjected to electrical and mechanical stresses while the equipment is in operation. Due to these stresses, contamination may take place as a result of chemical interactions with windings and other solid insulations used. Transformer oil testing is carried out to determine these contaminants and analyse the amount of chemical degradation of Oil.
Transformer oil degradation occurs mainly due to water ingress & liberation of gases due degradation of insulation materials. Monitoring Water levels and Dissolved Gas analysis of Transformer oil forms the basis of predictive maintenance of Transformers.
Predictive maintenance of Transformers helps in:
Chem-TechTM carries out testing of Transformer oil as per internationally accepted ASTM, ISO & IS Test Standards.

Kinematic Viscosity is a measurement of the resistance of the oil to flow through a capillary tube of the viscometer. It is the most fundamental property of a lubricant. Viscosity of lubricants is measured in case of fresh oils to check the Grade of the oil . in case of used oils it gives idea about change in physical properties due to oxidation, dilution or any external contamination. It is the most fundamental property for testing of any lubricant or petroleum product.
Methods Adopted by Chem-Tech for Viscosity Determination:
Total Acid Number determines the amount of acid present in the lubricant. Acidity of the lubricant increases due to the stresses or environmental factors affecting the lubricant. Excess amount of acid in the lubricant will lead to corrosion or failure of equipment.
Methods adopted by Chem-Tech Laboratories for Acid Number Analysis:
Water or Moisture is the most common contaminant in any lubricant or petroleum product. Monitoring the level water in sample is of prime importance to avoid malfunctioning of the equipment or machine.
Water content in petroleum products can be determined by following 4 test methods:
Methods Adopted by Chem-Tech for Water / Moisture Content Determination:
Density is fundamental characteristic of any petroleum product. It is the measurement of weight per volume of the sample.
It is measured by:
Methods Adopted by Chem-Tech for Density Determination:
Flash Point is the lowest temperature at which the vapours of the petroleum product catches fire momentarily in presence of air when an ignition source is applied to the sample.
Flash point are normally conducted by three methods:
Methods Adopted by Chem-Tech for Flash Point Determination:
This test determines the total sediments present in petroleum . This is a Chem-Tech Laboratories validated method, It is modification of ASTM D 893 for determination of Total Insoluble content in Toluene. It is a centrifugal method for determination of Insoluble content.
It determines wear metals, dirt dust and debris present in petroleum products & Lubricants.
