GridscanTM
H2 sensors for In-situ Dissolved Gas
Analysis with New DGA Technology
GridscanTM chip-based technology
uses palladium-nickel alloys
with an advanced proprietary
materials coating to protect the
sensor and enable it to measure
hydrogen in both gas and oil
phases of power transformers
and ancillary equipment.
This solid-state sensing element is
hydrogen specific and insensitive
to other transformer gases. It
may be immersed directly in the
transformer oil during normal
operation and measure hydrogen
levels continuously. The GridscanTM
platform has no consumable
components or any degradation
of the sensor, does not require
carrier or calibration gases to
maintain accuracy and has a
theoretically unlimited useful life.
