Factory Acceptance Testing

Factory Acceptance Testing

See for yourself why your Cat® generator won’t let you down in the field. Every Cat generator set undergoes a rigorous series of factory tests, and this is no different for a customised solutions package. Over twenty test cells are dedicated to special testing, with the capacity to test open, canopied, and containerised generator sets at both inductive and resistive loads.

Using up to 12 MW resistive capacity, a 3 MVAr inductive capacity and a 750 kVAr capacitive capacity, we can test low and high voltage generator sets and multiple units synchronised together, simulating site conditions and installations.  


Test Procedure 

We begin by testing the impact load acceptance to demonstrate that the response of the generator to load meets the specified limits of rated voltage, frequency, and recovery time. You can monitor the transient graphs for voltage and frequency in real time. 

During the second stage, we prove the full functionality of the generator by simulating the protection alarms and shutdowns, so you can visualise the operation and safety of your generator set, giving you total confidence that it won’t let you down in the field.  

The final stage is the load-proving test. We demonstrate the capability of your generator to continuously carry rated load for a period of time, depending on the required continuous or standby ratings. Key parameter readings are taken at regular intervals specific to your requirements. 

Why not come and see our industry-leading facilities and witness your generator package being tested?

Gen sets provide temporary power for the USS Midway museum

With a power system designed to provide temporary electricity for an 11-day span, the USS Midway was able to upgrade its entire electrical infrastructure without having to close to the public for a single day. As a trusted solutions provider, Hawthorne also provided 25 ekW and 35 ekW rental generator sets to various parts of the ship at four other special events throughout the year.
