Generator Operation
If you have a standby power generator that you plan to use in case the power goes out, it's important to frequently check that your generator is running properly and ready for emergencies. Your check of the equipment should include the actual connection and running of your generator to assure it is in proper working order. This test will also familiarize you with the proper operation under nonemergency conditions.
Standby generators must have a double-throw switch. The safe and proper connection of your generator requires a transfer switch to completely disconnect the generator from the cooperative's electric system. This switch prevents the flow of current into the utility’s lines, which could electrocute line workers who are working to restore power or could present a hazard to people or livestock near downed power lines. The switch also protects the generator from potential damage when regular electric service is restored. The transfer switch is typically owned by the consumer and must be installed by a licensed electrician.
Before transferring the electric load, the generator must be brought up to speed. Once up to speed and generating the right voltage, the load can be switched to the generator. During this test, run your generator under load for an hour. This polishes any brush connections in the generator, plus it will dry out any moisture that has accumulated since you last used the unit.
Establish a periodic starting schedule to exercise the generator. Some manufacturers suggest operating a tractordriven generator at least one hour every three months. Engine-driven units should be operated more frequently to check battery charge levels and other starting components.
Also, use the generator every so often with a typical electric load to ensure that it can carry the load. Over the years, you may have added electric loads that weren’t taken into consideration when you bought the generator. Remember, your standby generator is like an insurance policy. It isn’t much good if it's not kept up-to-date. If you need assistance determining which generator will fit your home, farm or ranch needs, contact your local electric cooperative.
One final reminder: the quality of electricity generated by standby generators may damage sensitive electronic equipment such as home electronics and computers. Use a quality surge protector to protect your equipment or simply unplug the devices while operating the generator. Before operating your generator, read and follow your generator’s instruction manual.
Make sure the generator is brought up to speed and operating at the proper voltage before connecting any load to the generator. Failure to do this may damage your equipment.
