Why Do Diesel Generators Need False Load

As the emergency standby power supply after power failure, diesel generator set is in standby state most of the time. Once power failure or power failure occurs, the standby diesel generator set plays a vital role.However, we often find that the performance of diesel generator set has problems after the power supply failure, which shows that many users do not pay enough attention to the knowledge of AC false load for diesel generator set detection and maintenance.

1、 Why do we need AC false load for diesel generator set inspection and maintenance.

(1) Test diesel generator set.

By detecting the AC false load of diesel generator set for maintenance, the unbalanced load capacity of diesel generator set can be detected to ensure the steady-state voltage regulation rate, steady-state frequency regulation rate, transient voltage regulation frequency, voltage recovery time, transient frequency regulation rate, frequency recovery time and continuous operation detection of diesel generator set.

(2) Test UPS.

Output voltage unbalance, output voltage stabilization accuracy, overload capacity, dynamic voltage transient range, battery switching time, backup time, bypass inverter switching time.

2、 Main functions of AC false load for diesel generator set detection and maintenance.

(1) Query function.

Query the diesel generator set, search the abnormal record, query the diesel generator set detection data.

(2) Online communication.

The detector can be connected with upper computer through RS232 / RS485 interface.

3. Intelligent control and data processing function.

Data transfer: after testing, the collected data can be transferred to U disk.

Online monitoring of the electrical parameters of the tested equipment.

Data processing software function: the data processing software is used with the detector. The detection parameters can be set to analyze and deal with the electrical parameters, operation status and abnormal records detected by the detector; Intelligent query, display and print chart.

Automatic detection can be realized by setting parameters of detection equipment.

4. Parallel function.

The equipment is equipped with RS485 digital parallel interface, which is controlled by the host and records the detection process.

5. Shutdown protection function.

On the basis of general AC false load and load box, an intelligent control system is added to detect and maintain the AC false load of diesel generator set, which can set the protection of phase loss, overvoltage and undervoltage. Once the parameters detected by the equipment exceed the set parameters, the equipment will give an audible alarm and automatically shut down for protection.

To sum up, in order to effectively avoid the occurrence of accidents, users should strengthen the daily detection and maintenance of  power generator, establish perfect detection and maintenance procedures of diesel generator set, and regularly maintain the diesel generator set.If you want to know more, please contact us by email dingbo@dieselgeneratortech.com.
