This month’s deferred on-load generator test passed as expected.
The generator was started manually, then the mains supply to BOL1 was isolated, and the generator then ran on-load 09:01 – 12:10
This extended period of load testing covered planned upstream maintenance work by the utitlity company.
The mains supply was re-established and the generator was shut down manually in the expected timeframe.
All measured values were within their normal ranges.
