What to Know Before Renting a Generator?
Several factors influence the selection of the size of a generator set. Among them, the characteristics of the system's electrical load are a significant factor. Before renting a diesel generator set, users should carefully consider the following points:
Is it for a regular power generator set or a backup generator set?
b. Considering the increased electricity consumption for future system enhancements
c. Voltage drop permitted by the system
d. Motor startup conditions
2. Engine Power Calibration
Our standard diesel generator sets, designed for general user needs, are capable of supplying power continuously for 12 hours at rated power (with the ability to operate at 110% of rated power for 1 hour). In cases where power outages are infrequent and of short duration, users can opt for generator sets that are rated as backup units. These units operate at an average of 80% power for no more than 200 hours annually, with the total runtime at full power not exceeding 25 hours per year.
3. Issues to Be Aware of When Matching Generator Sets with Three-Phase Motors
Three-phase AC induction motors are commonly used in mechanical engineering. Due to their starting characteristics, these motors are directly connected to the power supply system. Direct online startup would generate surge currents up to six times the motor's rated current. With a soft start device in place, the startup current is very smooth and will not cause a shock to the generator set. When matching the generator set with the capacity of a three-phase motor, it is recommended to consider a safety factor of 1.5, which is 1.5 times the motor capacity (must be soft start).
