Generator Testing

Q: We have a generator that doesn’t meet the 30% load for the monthly run so we have to do an annual run with the load at 50% for 30 min and 75% for 60 min for a 90-minute continuous run. Our contractor did the annual run but he ran it with 52 % for 30 min , 75% for 30 min and 81% for 30 min, then he continued to run it for 2½ more hours dropping the percentages as he went for 4 continuous hours at not less than 30%. My question is does these meet the intent of the standards for both an annual and a 3-year load test?

A: Yes… I would say the test as you described meets both the annual requirements and the 3-year test requirements. The generator load testing requirements are minimum load settings, and it is permitted to exceed these minimums.
