In this article, we answer the most common questions about VisNet® Hub: the real-time monitoring device that operates in low voltage distribution substations to provide insight into substation efficiency and optimisation. How complicated is the VisNet® Hub to install? Providing you can answer these simple questions, installation is easy: Where will the VisNet be mounted? Where … 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
Countless specifications and strategies are being explored and adopted by electricity companies world wide based on the outcomes of trials and tests of low voltage (LV) network monitoring. It’s no small challenge: most electricity companies have significant numbers of secondary substations, and of these tens of thousands of substations, most have been installed in the … 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
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
