Generator sets play a vital role in ensuring uninterrupted power supply in a variety of areas, from hospitals and data centers to construction sites and remote industrial projects. However, to maintain long-term reliability and protect your investment, AGG recommends equipping generator sets with critical protection systems. These systems not only protect the generator set and extend its lifespan, but also help avoid costly failures and safety risks. Below are five key protection systems that every generator set needs:
1. Low Oil Pressure Protection
One of the most important protection systems in a generator set is the low oil pressure sensor. Oil is used to lubricate engine parts, reducing friction and preventing overheating. When oil is low, engine parts may rub against each other and cause wear and malfunction. The low oil pressure protection system automatically shuts down the generator set when the oil pressure is too low, preventing wear and alerting the operator to check the system.
Why it matters: If the generator set oil pressure is insufficient, the engine may be damaged within minutes of operation. All types of generator sets must be equipped with this basic protection device.
2. High Coolant Temperature Protection
Engines generate a lot of heat during operation, and the cooling system is responsible for cooling the equipment to maintain optimal operating temperatures. If the coolant temperature becomes too high due to system failure, insufficient coolant or extreme external conditions, the engine may overheat and cause potential damage. High coolant temperature protection monitors this parameter and initiates a shutdown or alarm if necessary to avoid equipment damage.
Why it matters: Overheating is a major cause of engine failure. The protection system maintains normal operating temperatures and ensures that the generator set does not operate beyond its thermal limits.
3. Overload and Overcurrent Protection
Electrical overload and overcurrent conditions can seriously damage a generator set's alternator, wiring and connected equipment. These conditions usually occur when the output of the generator set exceeds its rated power or when there is a fault in the electrical system. Overload protection ensures that the generator set shuts down or restricts power delivery to prevent damage.
Why it matters: Overloading can affect the life of the generator set and create a fire risk. Proper overcurrent protection protects the equipment and the operator.
4. Under/Over Voltage Protection
Voltage fluctuations can affect the performance of generator sets and the equipment they supply. Undervoltage can cause connected equipment to malfunction, while overvoltage can damage sensitive electronic equipment. Generator sets equipped with an integrated voltage monitoring system can detect abnormal voltage levels and take corrective action or initiate a shutdown function to avoid equipment failure or damage.
Why it matters: For sensitive applications such as data centers and medical centers, a stable voltage is essential to ensure safe and consistent power output.
5. Fuel System Protection
The fuel system is critical to the continued operation of the generator set, and any interruption could result in generator set failure. The fuel protection system monitors the fuel level, detects water contamination in the diesel fuel, and checks for abnormal pressure. Advanced systems can detect fuel theft or leakage, which is especially important for generator sets operating in remote or unsafe areas.
Why it matters: Protecting the fuel system ensures efficient, safe and uninterrupted operation while reducing the risk of environmental hazards and economic losses from leaks or spills.
