While standing a generator watch, you must be alert and respond quickly when you recognize a problem. You might not have control of every situation but at least you can secure the generator and prevent serious problems.
Your primary purpose is to produce power in a safe and responsible manner. You may notice maintenance or repair actions that need to be rectified but do not require immediate attention and do not affect your watch Make note of these problems so that they will be taken care of by the repair crew. In addition, concentrate on doing your job properly, and your efforts will pay off.
A generator watch involves performing operator maintenance, maintaining the operator's log, operating a single generator, or operating paralleled generators.
Operator maintenance generally includes whatever you have to do to start the generator set and keep it running smoothly and safely. Equipment must be inspected systematically so that defects can be discovered before a serious failure occurs. Operator maintenance includes both prestart checks and operating checks.
When starting the generator set and preparing to put it on line, you expect everything to go well. A systematic inspection before start-up will help ensure that the generator will operate properly. To do a prestart checkonthe generator, make the following inspections:
1. Ground cable. See that the cable is intact and that the connections are tight.
2. Engine. Compare the actual lube oil level to the appropriate markings (running level or stopped level) on the dipstick. The stopped level is, of course, appropriate for prestart checks. Add oil as required.
Check the engine for loose connections; free action of all moving parts, such as the throttle linkage and the emergency shut-off lever; and for leaking oil, fuel, or coolant.
3. Coolant system. Check that the coolant is at the required level. Add coolant as required. Using an antifreeze solution tester, check that the antifreezeContinue Reading
