Transformer Oil Testing and Analysis

Dielectric Fluid Analytical Services 

Transformer oil testing and analysis is a cost-effective preventive maintenance tool for your electrical power system.

The insulating fluid in a power transformer performs two major functions:

  1. Serves as electrical insulation to withstand the high voltages inside the transformer
  2. Acts as a heat transfer medium to carry out heat generated within the transformer windings

Don’t ignore fluid testing until a failure occurs. Transformer oil maintenance is the key to transformer reliability, performance and longevity. Your transformer’s insulating oil should be free from moisture, dissolved gases and particles that accumulate as the oil ages. Even some new oils may require treatment to limit these contaminants to acceptable levels. Sampling and analysis of the fluid form the cornerstone of transformer preventive maintenance.

Our Oil Testing Services

RESA Power Service offers expert oil laboratory and field services to customers around the world. Samples can be mailed into our full service laboratory or drawn by one of our highly trained field service technicians. Your transformer fluids will then be analyzed to identify any potential or current problems with your equipment.
