Proving a Natural Gas Generator Set With Your Own Load
For a 400 kW, 500 kVA, 50 Hz natural gas generator set, the demonstration should use the buyer's actual load profile and gas supply, not a generic test bench.
Ask the supplier to demonstrate the natural gas generator set against your own load profile rather than a generic resistive bank. Because the reference unit is rated 400 kW prime output at 500 kVA and 50 Hz, the demonstration should show how it behaves under your real mix of motor starting, steady resistive load, and step changes, and on your actual gas supply conditions.
In the request for quotation, ask what load bank or facility the supplier will use, whether your load can be connected directly, and how the test will record voltage and frequency response at each step. For an acceptance test, agree in advance which load steps count as pass or fail, how long each step is held, and who supplies and pays for the test gas.
Treat the catalog figures as reference values for the model family, not as guarantees for the unit you receive. Ask the supplier to state the conditions behind any performance figure it quotes.
Before requesting a quote, confirm with the supplier what demonstration load it can accept, whether your gas composition and pressure are within its test setup, what instrumentation and records you will receive, and which acceptance criteria will be written into the contract.
