Fuel pressures for gaseous generator systems is critical when it comes to proper operation of the engines used in generator sets.
While unfortunate, inadequate fuel plumbing conditions are very common.
Some generators can consume in excess of 1,000,000 BTU's per hour so properly sized fuel plumbing at the correct pressure is a must.
To observe fuel pressure correctly, attachment of a manometer and connection of an external load bank to the generator is necessary. This will allow for observations of the fuel pressure at different load stages.
Although this is one of the most important steps for a generator installation, the procedure is rarely done by companies. Without observing gas pressure, while stressing the unit to the maximum output capacity, a true picture will not be possible.
If fuel pressures are not correct engine damage will occur, and voltage transients combined with low voltage conditions will exist. Due to the poor power quality damage will also occur to any electrical device attached to the system.
