Dingbo Power Takes You to Know the Knowledge of Diesel Generator

Nowadays, with the increase in electricity consumption in various industries, generators have become the preferred backup power equipment for various industries, and are indispensable power equipment for enterprises in their production and operation processes. Then Dingbo Power will take you to learn more about diesel genset. We hope these contents will help you.

What is power factor?

Power factor (pf) is usually defined as the ratio between kilowatts (kW) and kilovolt amperes (kVa) extracted from electrical loads. It is determined by the load connected to the generator. The pf on the generator nameplate relates kVa to the kW rating (see formula above). Generators with higher power factors are more effective in transmitting energy to connected loads, while generators with lower power factors have lower efficiency and result in increased power costs. The standard power factor of a three-phase generator is 0.8.

What is the difference between standby, continuous, and primary rated power?

Backup generators are most commonly used in emergency situations, such as during power outages. It is very suitable for applications with other reliable continuous power sources, such as public power sources. It is recommended to use only during power outages and regular testing and maintenance.

The main power rating can be defined as having "unlimited operating time", or is essentially a diesel generator that will be used as the main power source rather than just a backup or standby power source. The main rated power generator can supply power without grid power, which is often seen in industrial applications, such as mining or oil and gas operations located in remote areas without access to the grid.

Continuous power is similar to main power, but has a basic rated load. It can provide continuous power supply for constant loads, but does not have the ability to handle overload conditions or work under variable loads. The main difference between primary and continuous ratings is that the primary generator set is set to provide maximum power for unlimited hours under variable loads, and they typically include a short-term overload capacity of around 10%.

What is the function of an automatic transfer switch?

When a standard power supply fails, an automatic transfer switch (ATS) transfers power from the grid power supply to an emergency power source (such as a generator). ATS senses a power outage on the line and sends a start signal to the engine panel. When the standard power supply is restored to normal power, the ATS transfers the power back to the standard power supply and shuts down the generator. Automatic transfer switches are typically used in high availability environments, such as data centers, manufacturing plans, telecommunications networks, etc.

Can the generator I am looking for be connected in parallel with a generator I already own?

Diesel generator sets can be connected in parallel to meet redundancy or capacity requirements. Parallel generators allow you to electrically connect them to combine their power output. Parallel connection of identical generators will not be a problem, but the overall design should be considered extensively based on the main purpose of the system. If you try to connect different generators in parallel, the design and installation may become more complex, and it is important to keep in mind the impact of engine configuration, generator design, and regulator design.

Can a 60Hz generator be converted to 50Hz?

Generally speaking, most commercial generators can convert from 60Hz to 50Hz. The general rule of thumb is that a 60Hz machine runs at 1800Rpm, while a 50Hz generator runs at 1500Rpm. Most generators only need to lower the engine speed to change frequency. In some cases, it may be necessary to replace parts or make further modifications. Larger machines or machines that have already been set to low speeds are different and should always be evaluated based on the specific situation.
