It’s here! The much anticipated next generation of the electricity distribution ‘Common Network Asset Indices Methodology’ also known by the catchy acronym CNAIM. Developed for the assessment, forecasting and regulatory reporting of asset risk in Great Britain, this methodology is based on more than 20 years of development and experience. This new version replaces its 2016 predecessor, for … Read more
The final part of the basic oil quality assessment trio (along with Moisture & Acidity) is the Breakdown Voltage Strength otherwise known as the BDV. The BDV is an important factor in understanding the quality of the oil and is affected in many ways. Often there is a direct correlation between a high moisture content … Read more
The next assessment which forms part of the basic oil quality assessment on any insulating medium (along with Moisture & BDV) is the acidity content of the oil. The acidity content of a mineral oil should be determined in accordance with the IEC 62021: Insulating liquids. Determination of acidity. Automatic potentiometric titration methodology. The standard covers multiple fluid mediums and fluids such … Read more
6 signs you need predictive maintenance Predictive maintenance (PdM) – using equipment monitoring and data analysis tools and techniques to spot problems in processes and defects in equipment to predict when remedial work will be needed – isn’t a new concept. It’s all about minimising the risk of asset failure. If you’re thinking about the … Read more
Our next blog takes us onto moisture content, which forms part of the basic oil quality assessment (along with acidity & BDV) on any insulating medium such as mineral oil. The moisture content of an oil should be determined in accordance with the IEC 60814: Insulating liquids. Oil-impregnated paper and pressboard. Determination of water by automatic coulometric Karl Fischer titration methodology by use … Read more
The world of Dissolved Gas Analysis (DGA) is a complex place and although we cannot cover everything in this blog, we will try and provide you with a basic understanding. Why carry out DGA on oil samples? DGA is the only way to understand the operational condition of any oil filled electrical asset. When an asset suffers a thermal fault … Read more
