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. Over twenty test cells are dedicated to special testing, with the capacity to test open, canopied, and containerized 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 synchronized together, simulating site conditions and installations.
