Normal Voltage And Frequency Fluctuation Range Of Diesel Generator Set

For many new users who purchase diesel generator sets, they may encounter this problem. When you receive and open the diesel generator set, you will find that the picture shows the voltage as 430V and the frequency as 52.5HZ. The frequency is higher than 50HZ? And the voltage is also higher than 400V? In fact, this is a normal fluctuation range. Because the unit has no load, the frequency and voltage will increase somewhat. After being loaded, it will decrease. Therefore, this voltage frequency is within the normal range and there is no need to worry.

In view of this phenomenon, the diesel generator manufacturer Dingbo Power hereby summarizes and shares with customers some allowable variation ranges of the unit for reference:

1.The diesel generator set can run continuously at full load for 12 hours, and its overload capacity for 1 hour is 110%. The generator has an over - current capacity of 1.5 times for 15 seconds, and it is allowed to repeat this operation mode after a period of time;

2.Under any steady - state load condition, maintain the voltage within ±1% and the frequency within ±0.5% of the rated value deviation;

3.In the transient state of sudden start - up with load, the voltage is not less than 90%, the frequency is not less than 95%, and the recovery time is within 7 seconds. The transient process is due to the unit carrying loads in batches from no - load;

4.If the motor starts directly, the current is considered to be 6.5 times. It can start automatically within 7 - 10S after the power is cut off, and establish the voltage frequency to reach the rated value. The diesel generator can carry 50% of the starting load of the rated capacity, of which the maximum starting load is allowed to supplement 20% of the rated capacity of the generator. Full load can be carried after 5S;

5.The voltage regulation range is ±5%, and the frequency regulation range is ±2.5%;

6.The diesel generator set can reach the rated speed and rated voltage within 15S after receiving the starting signal, and has the full - load condition.
