Frequently Asked Questions

Where do you put a hydrogen sensor?

A transformer hydrogen sensor should be placed at the top valve or in a mid or bottom drain valve. Hydrogen sensor 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.

What are hydrogen sensors used for?

Transformer hydrogen sensors are used for measuring the level of dissolved hydrogen in the transformer insulating fluids (oils). This is also referred to as dissolved gas analysis or DGA. The presence of hydrogen is an early indicator of an incipient fault in a transformer.
