HOW TO SIZE A GENERATOR – AUSGEN

Posted on 01 April 2013

Selecting a generator that can handle all of your power generation needs is one of the most important aspects of the purchasing decision. Whether you are interested in prime, temporary or standby power, if your new generator can’t meet your specific requirements then it simply won’t be doing you any good because it can put undue stress on the Generator and even damage some of the equipment connected to it. Unfortunately, determining exactly what size of generator to purchase is often very difficult and involves a number of factors and considerations.

Making a choice amongst single phase, three phase, kW, KVA, welder, standby or motor starting generators can be confusing. To prevent such confusion, Australian Generators has written this article to help you get a better idea of how the sizing process works and some key things to keep in mind. This is not a substitute for a certified electrician, which we always suggest talking to before Purchasing (Australian Generators can assist you here), but it should provide you with enough information to get an understanding of some of the key factors that are involved.

Generator Size Variations: With the latest advancements in the field of power generation, Australian generators are now available in a wide range of sizes. Australian Generators with power supply capacities of 1Kva to 80Kva are readily available for the home use, while Australian industrial generators are anywhere from 50Kva to over 3 Megawatts. Australian Generators can build multi set applications where up to 32 generators can be synchronized to work as 1 (96 Megawatts). Portable Generators are available for homes, caravans and small offices, but larger businesses, data centers, buildings, and mining applications need to use a much larger sized Australian Diesel generator / generators to meet their power requirements.

Australian Generator Sizing: Many people believe smaller generators can be used for standby power because they are not running all the time. This is not only wrong but can actually be very damaging. Unfortunately, generator under sizing is one of the most common mistakes committed by purchasers. Not only does it involve the risks of damaging your new generator, but it can also damage other assets connected to it, create hazardous situations, and even limit the overall efficiency of the unit and/or the business relying on it. If nothing else, the key thing to remember here is that more is always better than less.

How to Determine the Right Australian Generator: While there is no substitute for the services of a qualified electrician (Australian Generators can assist you here) the following information will allow you to make a more qualified decision with a better understanding for choosing the right generator for your application:

Know You’re Requirements: Going to an auction site or a dealer and buying the cheapest or the best (so they say) is not the option.

- Make a list of the items that need to be powered by the generator

– Make a note of the starting and running Current of the respective items

– Calculate the total power requirements in KVA or KW

– Phone or Email Australian Generators and one of our technical representatives will be able to assist you.

How to Find the Starting and Running Current: Getting the right starting and running current of the devise you require to run is very important, these can be found on the manufacturer’s plate or in the hand book provided with the item. If these cannot be found call Australian Generators and we will be able to assist you.

Power Requirement Charting: It often happens that you lose the owner’s manual or for some reason can’t find the power requirement specification of the tools and/or other electrical devices you’re running. Below is an Ausgen sample power consumption chart.
