Applications
Hydrogen cooled synchronous
compensators
Analysers available for CO2 or N2
purging
katharometer sensor, based on Hitech’s
proven thermal conductivity technology, is
calibrated over the three ranges. The inherent
stability of this system means infrequent
calibration and a low cost of ownership.
There are no consumables and no spares are
required for the first two years of operation.
The K6050AP analyser has three ranges
to monitor the hydrogen purity and the
two stage gas-purge cycles. A single
Hydrogen cooled turbo-generators
The K6050AP analyser has been
designed specifically for use in power
stations. Modern turbo-generators produce
a great amount of heat and the most efficient
way of removing this heat is by enveloping
the parts in hydrogen, because hydrogen
has seven times the cooling capacity of air.
It is possible for air to leak into the system,
so it is essential to monitor the hydrogen
purity for both efficiency and safety - as a
hydrogen/air mixture will produce a potentially
explosive atmosphere. When maintenance
needs to be carried out, the atmosphere
inside the turbo-generator has to be replaced
with air. This cannot be a direct replacement
because of the explosive mixture that would
be produced in the process. Instead, an inert
gas, usually carbon dioxide, is used to purge
the hydrogen, then air is introduced to purge
the carbon dioxide. The same procedure must
be followed in reverse when replacing the
hydrogen atmosphere.

experts.

The K6050AP portable analyser is a
complete instrument in a rugged case. It
is the portable equivalent of our fixed version
K1650AP analyser, having rechargeable
batteries (supplied) capable of lasting for
a full purge cycle. A sample pump, 0 to 1V
recording output, a flowmeter and needle
valve are all included as standard.
Sample conditioning filters are available,
if required, to remove potential oil mist and
water vapour from the sample prior to analysis.
For sites using nitrogen as the purge gas
(instead of CO2) please contact Hitech for an
alternative solution.
