Brief Description about the division:

RTL Kolkata is set up with a view to cater to the testing certification &evaluation needs of electrical power equipment manufacturing industries, utilities of consumers in the eastern region in 2006. It also acts as a liaison Unit of CPRI with various clients in the region & coordinates their test requirements which are beyond the scope of RTL Kolkata but within the capabilities of Bangalore & other units of CPRI. The facilities available at the laboratory are also used in research & consultancy activities. CPRI Kolkata is a NABL accredited laboratory as per ISO/IEC 17025:2017.

Test facilities:

The laboratory is equipped with facilities to carry out testing & certification of insulating oils in power transformer as per IS 1866-2017/IEC 60422:2013. The dissolved gas analysis (DGA) of Power transformer, an important diagnostics tool is available at RTL Kolkata for assessing the internal condition of the transformer. The laboratory has the test facilities like DGA, Furan Analysis, Electric Strength, Titration, Flash Point, Pour Point, Water Content, Tan delta, Resistivity etc. High Performance Liquid Chromatography (HPLC) is another important diagnostic tool to evaluate Furfural Content for assessing the condition of solid Insulation in Power Transformer. 

Research capabilities / expertise:

• Advanced polymeric dielectric systems (nanocomposites, hybrid blends, and self-healing materials) with superior performance, longer lifespan, and enhanced safety for high-voltage insulation. 
• Hybrid natural esters derived from vegetable oils and modified with synthetic additives as advanced insulating fluids for power transformers and other electrical equipment.
