Oil analysis keeps power flowing

Regular oil and fluid analysis is not only vital for monitoring the condition of engines and hydraulic equipment, it is also an important tool in effective maintenance of transformers, turbines and other equipment used in generation and distribution of electricity.

Techenomics International provides fully independent, state-of-the-art, accurate testing and analysis of transformer oils used to insulate many transformers and other electrical distribution equipment, and turbine oils, which are used extensively in the power generation industry.

Techenomics’ CEO Chris Adsett says power generation is an integral component supporting the development of emerging economies. “Without power many countries in Asia, Africa and Latin America will not sustain their ongoing growth. While renewable energy has an increasing role to play, it is impossible to achieve the projected power needs of these nations without further development of coal-fired power stations.”

However, he says it is important that existing and new coal-fired plants, as well as other power generation sources, be run as efficiently and environmentally-friendly as possible and Techenomics’ innovative total fluid management solutions have a role to play in this process.

“Dielectric analysis of transformer oil is an essential part of a cost-effective maintenance program that can predict issues before they lead to breakdown or failure. The analysis of insulating oils provides information about the oil, but also enables detection of other possible problems, including contact arcing, aging insulating paper and other latent faults.

“The dielectric strength of transformer oil is defined as the maximum voltage that can be applied across the fluid without electrical breakdown,” Chris Adsett says.

“Because transformer oils are designed to provide electrical insulation under high electrical fields, any significant reduction in dielectric strength may indicate that the oil is no longer capable of performing this vital function.”

Some of the things that can result in a reduction in dielectric strength include polar contaminants, such as water, oil degradation by-products and cellulose paper breakdown.

Chris Adsett says turbines are the lifeblood of power generation operations and turbine oils play an important role in keeping turbines running effectively. “Techenomics turbine oil analysis packages are designed to identify the core functions of the oil and to monitor the operating conditions.

“Analysis enables operators to schedule proactive maintenance procedures and carry out meaningful programs to protect the systems.”

Turbine oils need to be free of water and contaminants; have the thermal ability to withstand high operating temperatures; the ability to combat the by-products associated with oxidation and acid build-up; and most importantly, lubricate the necessary internal components while having the capability to resist against shear stress.

Through its extensive network of accredited laboratories and fully qualified staff, Techenomics provides in-depth analysis of lubricant properties, wear and contamination affecting turbine performance and suitability of oil life.
