Factory Acceptance Checks for a 90 kW Diesel Generator Set
Buyers should turn the 90 kW prime and 100 kW standby ratings into pass or fail checks that can be witnessed at the factory acceptance test.
A buyer ordering a 90 kW prime / 100 kW standby diesel generator set should decide before the factory acceptance test which results will count as pass or fail, rather than accepting a general demonstration. Start with the ratings: will the unit be run at 90 kW prime output and at 100 kW standby output, and for how long, with what load steps, and at 60 Hz and 1,800 rpm? Ask the supplier to state the acceptance criteria for each point in the request for quotation.
Practical checks can include whether frequency and engine speed hold within limits the buyer sets, how load steps are applied, and what records are issued. A buyer might ask: is the test witnessed, which instruments are used, and are results recorded per load point? Treat catalog values such as 90 kW, 100 kW, 60 Hz, and 1,800 rpm as reference values, not as proof that a supplied model will meet them.
Before requesting a quote, confirm with the supplier which tests are included, who witnesses them, what pass or fail criteria apply, and what documentation is provided.
