Megger 6220-484 Pair of Spherical Electrodes for Oil Testing (OTS)
What are the Megger 6220-484 Spherical Electrodes?
The Megger 6220-484 Spherical Electrodes are designed for UK HV maintenance technicians and electrical engineers performing transformer oil testing using Megger OTS AF and PB series oil test sets. These precision spherical electrodes create the correct geometry for breakdown voltage measurements ensuring reliable and repeatable results when assessing insulating oil condition.
They are ideal for substation testing teams, transformer service engineers and technicians responsible for oil quality assessments in industrial and utility environments.
Why do spherical electrodes matter during oil testing?
Spherical electrodes help maintain a uniform electric field within the oil sample which improves measurement consistency and reduces the effect of surface imperfections. This leads to more repeatable breakdown voltage readings and helps technicians verify whether transformer oil meets safety and performance standards during routine maintenance.
