While rare, we do on occasion have transformers available in our inventory. These are typically sized on our website by kilovolt-amperes or simply “KVA”. This measurement expresses the apparent total power that is available in a system. Normally, you will see these alongside a power factor value to indicate the efficiency of power transfer.
Transformers convert AC voltage levels for transmission, distribution, or safety reasons. They are categorized first by the conversion of voltage and by their purpose. For our purposes, you will see Dry-Type transformers that are used indoors and don’t require oil for cooling. This style is considered a safer option. You may also come across Step-Up or Step-Down transformers to adjust voltage levels as needed. This allows you to increase voltage for power distribution and, likewise, decrease voltage for just an individual machine.
There are also Isolation transformers to provide galvanic isolation between circuits that require minimal electrical noise for sensitive pieces of equipment. A more specific example of this is called a Drive-Isolation transformer, which is designed explicitly for Variable Frequency Drives to isolate and handle heavier harmonic loads.
