The Effect of Moisture Sensor Location on Reliable Transformer Oil Monitoring
Study of Water Diffusion in Stagnant Oil
Power transformers are among the most valuable and important assets in electrical power networks, and moisture is one of the key factors impacting the operational performance of transformer oil.
Traditionally, the moisture content of oil has been determined using laboratory analysis of oil samples, but on-line monitoring is becoming increasingly popular. This is due to the fact that it provides realtime data that enables early fault detection, allowing the operator to take timely corrective actions before a problem can escalate.
