What is the difference between kW and kVa?
The primary difference between kW (kilowatt) and kVA (kilovolt-ampere) is the power factor. kW is the unit of real power and kVA is a unit of apparent power (or real power plus re-active power). The power factor, unless it is defined and known, is therefore an approximate value (typically 0.8), and the kVA value will always be higher than the value for kW. In relation to industrial and commercial generators, kW is most commonly used when referring to generators in the United States, and a few other countries that use 60 Hz, while the majority of the rest of the world typically uses kVa as the primary value when referencing generator sets.
How do I determine what size Generator I need?
Getting a generator that can handle all your power generation needs is one of the most critical aspects of the purchasing decision. Whether you are interested in prime or standby power, if your new generator can't meet your specific requirements then it simply won't be doing anyone any good because it can put undue stress on the unit and even damage some of the devices connected to it. Determining exactly what size of generator to get is often very difficult and involves a number of factors and considerations. Call Asgard Power for assistance on getting the perfect system suited to your needs.
What is the difference between standby, continuous, and prime power ratings?
Standby power generators are most often used in emergency situations, such as during a power outage. It is ideal for applications that have another reliable continuous power source like utility power. It’s recommend usage is most often only for the duration of a power outage and regular testing and maintenance.
Prime power ratings can be defined as having an “unlimited run time”, or essentially a generator that will be used as a primary power source and not just for standby or backup power. A prime power rated generator can supply power in a situation where there is no utility source, as is often the case in industrial applications like mining or oil & gas operations located in remote areas where the grid is not accessible.
Continuous power is similar to prime power but has a base load rating. It can supply power continuously to a constant load, but does not have the ability to handle overload conditions or work as well with variable loads. The main difference between a prime and continuous rating is that prime power gensets are set to have maximum power available at a variable load for an unlimited number of hours, and they generally include a 10% or so overload capability for short durations.
How many hours can a diesel generator run continuously?
Generally speaking, the diesel generator set can operate for 8–24 hours according to the size of fuel tank, power output and power load. This is not a problem for short power outages. However, in a long-term emergency, you may need a larger fuel tank or regular refueling.
What is the most common generator failure?
A diesel generator being out of fuel is one of the most common problems owners run into. For this reason, make sure the generator fuel level is the first thing you check if your generator won't start.
How often should a diesel generator be serviced?
Most diesel generators require a minor service every 500 hours of operation and/or every 6 months. This schedule may need to be accelerated due to environmental conditions. Each engine manufacturer has their own requirements written into their owners manual. As a rule of thumb Asgard Power would recommend servicing your diesel engine every 250 hours / 1 year to extend the life of your valuable asset.
Why Do I Need to Service My Generator?
Your generator, like any engine, needs routine service and maintenance to ensure it performs when needed. Just like your car has scheduled minor and major services based on time/mileage, generators have services based on time and number of hours of usage. If your generator is used for backup power, keeping up with your maintenance will empower your generator to be ready when it’s needed.
