HVS' patented second generation nitrogen generator system was designed for use on transformer main tanks, tap changers, breakers and any other electrical device requiring a nitrogen gas-blanketed enclosure. This robust system offers a controlled environment to ensure consistent nitrogen purity and supplies compressed nitrogen gas at a much lower psi than traditional bottle pressures to significantly reduce the possibility of system leaks.
Other benefits include the following:
• Eliminates the need to lift and risks of replacing
nitrogen bottles
• Four non-powered alarm contacts monitor
condition of the nitrogen generator system
externally
• Industry standard lockable cabinet fits same
footprint as fully-enclosed inert air system, and
nitrogen gas line exiting the enclosure is in a
standard location to make installation easy,
especially in retrofit applications
• Positive pressure nitrogen gas regulation system
maintains transformer tank pressure between
0.2 and 5.5 psi to protect transformer oil from
oxidation and moisture absorption
High purity nitrogen gas is generated as needed and stored in a tank to provide a reserve supply of nitrogen in the event of power failure. Included SCADA output terminals monitor low/high transformer pressure, low storage tank pressure and control system temperature alarm. A coalescing filter assembly protects hollow fiber nitrogen membrane from particle contamination, while a climate control module regulates system temperature for optimum nitrogen purity (99% to 99.5%).
