SITRAM H2Guard Lite
SITRAM H2Guard Lite enables asset managers to check the
hydrogen health condition of the transformer’s insulating
liquid continuously. This provides the advantage of
trending Hydrogen creation / evolution based on historical
and present operating conditions.
The actual miniature sensing element is located in the
sensor tube which is installed on any suitable valve in
either the liquid phase or gas phase (headspace) of a liquid
filled transformer tank or the pipe system.
SITRAM H2Guard Lite can be easily integrated into superior
monitoring platforms using a standard protocol communication
interface.
