Transformer Oil Testing | BDV Test Explained | Live Sample Process In this video, we are showing the Transformer Oil BDV Test Process with live backside sample testing. Transformer oil testing is very important to check: Dielectric Strength Moisture Content Insulation Quality 👉 Normal BDV Value: 60–70 kV (New Oil) 👉 Minimum Acceptable Value: 30 kV If BDV comes below 30 kV, then transformer oil must be filtered or replaced to ensure safe and reliable operation. #TransformerOil #BDVTest #Electri

Live Transformer Oil Filtration at Substation. “Transformer oil filtration improves insulation strength, removes moisture, and increases the life of the transformer. Regular filtration keeps your transformer healthy and fault-free.” #TransformerOilFiltration #PowerTransformer #ElectricalEngineer #SubstationWork #Maintenance #66kV | Er Muhammad Miyaji
