Generator Installation & Repair

Looking for generator repairs or replacements? Call (516) 671-3232 and be prepared for the unexpected.

Don’t get caught without power when you need it the most. If your generator isn’t working, make sure to have it inspected and repaired or replaced. How do you know when the time is right to install a new generator? One sign is if the maintenance calls become more frequent. For replacements or repairs, look to Maccarone Plumbing for immediate service in Long Island and Five Boroughs.

How Long Do Generators Last?

Many of the larger industrial generators are capable of lasting for decades. Your generator’s lifespan will depend on how it’s powered. Diesel-driven generators last the longest. It can operate anywhere between 12,000 and 30,000 hours. Once a diesel generator reaches this usage range, it will likely need significant maintenance.

A gasoline generator tends to last around 6,000 to 11,000 usage hours before maintenance is required. So, you’ll need to replace a gasoline generator sooner than a diesel one.

What Causes Generator Problems?

Overheating: If your required capacity increases, this will overburden your existing generator unless it was designed for such use. Increases in capacity intake occur when you move to a larger space that requires the use of more kilowatts, or when new electronic equipment is added, which increases your power usage. If your generator exceeds its proper ratio of frequency to voltage, it can easily overheat.

Overheating can also occur when there are unbalanced currents. Various system fault imbalances and other conditions will cause what’s known as “negative phase sequences,” which refer to unbalanced currents. This will cause the rotor’s double frequency currents to overheat, damaging the generator to the extent that it might need to be replaced.

Under voltage issues: When the AC voltage has less than 80% to 90% of its power frequency, it will operate at low power for at least one minute and lead to under voltage issues. If your system operates this way for an extended period of time, a brownout will occur, which can seriously damage the generator.

Over frequency: Another common generator problem is over frequency. Various generator faults cause the segregation of power into distinct parts. Consequently, there is an excess of power due to an imbalance between the generator’s load and available power. When a load is denied, the generator speeds up. The result is over frequency. Maintenance will have to be performed to decrease the generator’s frequency and speed.

A generator can also suffer from a “loss of synchronism protection.” This phenomenon occurs when the generator’s power systems are out of sync, causing significant changes in currents and voltages. When power systems are out of sync, the currents are at a maximum while voltages are at a minimum. This problem will require professional maintenance service and eventually a generator upgrade.
