Put our VA transformer experience to work for you. Call today at 510-490-2187. Understanding VA Transformer SizingA VA transformer is a terminology used in sizing the transformer. To understand the term you need to understand the abbreviation. VA stands for V = Voltage Calculation VA Transformer PowerIf a VA transformer is rated at 120VA it means that it can handle 120 volts at 1-ampere or 1 amp of current. The VA is short for volt-ampere which is a designation of power. All electrical devices come with a VA rated nameplate on them with power usage. When you use a transformer to change voltage for electrical equipment or for electric motors you need to take in consideration the VA of the equipment. The load amps are always calculated after the device is started and running. Most equipment has a starting current, which is usually higher than the running mode. When figuring the size of transformer you will need to multiply the voltage times the load current and then multiply by 125 percent at start up to factor in the load. Always use a little higher VA capacity in the VA transformer that you select, never go with a lower capacity VA transformer or you could damage your equipment. Sizing An Industrial Control VA TransformerWhen sizing an industrial
control transformer three characteristics of the load must be
determined in addition to the minimum voltage required to operate the
circuit. They are: 2.) Sealed VA – Total steady state sealed VA is the volt-amperes that the VA transformer must deliver to the load for a extended period of time. 3.) Inrush Load Power Factor – This is difficult to determine without detailed vector analysis of all of the load components, which such a analysis is often not feasible. A safe assumption is 40% power factor. Twenty percent was commonly used for transformer calculations but, recently tests conducted on major brands of control devices indicated that it needed to be higher.
