Frequently Asked Questions
Where should a hydrogen detector be placed?
A transformer hydrogen detector should be placed at the top valve or in a mid or bottom drain valve. Hydrogen detector placement depends on whether we are monitoring the dissolved gas hydrogen content directly in the oil, or in the gas space (nitrogen blanket). The placement should consider safety, likelihood of getting damaged by passersby, and oil flow in the transformer.
