Question 1

How much power can a 350kVA generator actually deliver?

Accepted Answer

A 350kVA generator typically delivers approximately 280 kilowatts (kW) of active power. This calculation assumes a standard industrial power factor of 0.8 lagging. hw-adv-ta-r20-350kva

Question 2

What is the difference between Prime and Standby power ratings on this unit?

Accepted Answer

• Prime Power (PRP): The maximum capacity available for continuous use under variable loads with unlimited annual running hours.
• Standby Power (ESP): The maximum available power output for emergency backup use during a mains failure, typically limited to under 200 hours per year.

Question 3

How much diesel does a 350kVA generator consume per hour?

Accepted Answer

Fuel consumption depends heavily on the load placed on the system:
• At 100% load, it consumes roughly 70 to 80 liters per hour.
• At 75% load, consumption drops to around 50 to 55 liters per hour.

Question 4

How long can it run continuously before needing a refill?

Accepted Answer

With a standard integrated tank (such as a 1,000-liter or 1,300-liter base tank found on premium platforms), it can run continuously for 18 to 24 hours at 75% load. Connecting an external bulk day tank can extend this runtime to 48 hours or longer.

Question 5

Can a 350kVA system provide three-phase power?

Accepted Answer

Yes. A 350kVA industrial generator outputs standard three-phase electricity (typically 400V to 415V at 50Hz or 480V at 60Hz). This makes it perfectly suited to handle heavy industrial machinery, large commercial buildings, and factories.

Question 6

What standard maintenance schedule should be followed?

Accepted Answer

To keep the engine operating efficiently, adhere to the following maintenance routine:
• Every 250 Hours / 6 Months: Change the engine oil and primary oil filters.
• Every 500 Hours / Annually: Replace the air filter and fuel filters.
• Monthly: Conduct a routine load bank test if the unit is primarily used as an emergency standby backup.

Question 7

What is an Automatic Transfer Switch (ATS) and do I need one?

Accepted Answer

An ATS panel automatically detects a power failure from the main electrical grid. Within seconds, it signals the 350kVA generator to start up and flips the electrical load over to the generator. When grid power is restored, it seamlessly switches back and shuts the unit down safely.

Question 8

Can I run multiple 350kVA generators in parallel?

Accepted Answer

Yes. Using advanced digital controllers (such as Deep Sea or ComAp modules), up to 10 units can be synchronized to run in parallel. This setup is ideal for achieving N+1 power redundancy or scaling up capacity as your facility grows.

Question 9

How loud is a 350kVA generator during operation?

Accepted Answer

An open-frame model can be extremely loud, but when enclosed in a sound-attenuated canopy, the noise level is reduced to about 68 to 75 dB(A) at a distance of 7 meters. This is roughly equivalent to the noise level of standard curbside traffic.

Question 10

What type of facilities use a 350kVA generator?

Accepted Answer

Because of its high output capacity, it is heavily relied upon by:
• Mid-to-large manufacturing factories
• Data centers and telecommunication hubs
• Hospitals and medical facilities
• Large-scale construction infrastructure sites
