Defender 3kVA Portable Transformer 110V 3000W (E203010)

Product Information

The calculation for a three-phase transformer kVA is a little different from the calculation for a single-phase kVA. transformers are often favoured as it's a lower voltage that reduces the risk of harm if a cable is accidentally cut or damaged.

Ventilated:A three-phase ventilated transformer is useful for many types of general indoor and outdoor loads, both industrial and commercial, including lighting applications. The electrical load that connects to the secondary winding requires a particular input voltage, or load voltage.Blakley Electrics designs and manufactures wide range of power transformers in ratings ranging from 100VA to 250kVA and in voltages from 12 volts to 3300 volts. You can determine that primary voltageby using the ratios of current and voltage from the transformer’s primary and secondary coils. Once you’ve located or calculated these two figures, you can use them to figure out the load’s power requirements in kilowatts. A 3kVA 110v Portable Transformer featuring 2 x 16A outlets designed for use with corded products such as drills, grinders, saws, lighting products, heating and ventilation products.

If you use a chart, you’ll locate your system’s voltage and amperage in the rows and columns and then find the kVA listed where your chosen row and column intersect.So if you’re working with a three-phase transformer, instead of multiplying the voltage by the amperage and dividing by 1,000 to get the kVA, you’ll multiply the voltage by the amperage by 1.

To use their transformers effectively, businesses need to know how much power their particular transformers can give them. Plugging these numbers into the equation given above yields 300/150 = 10/t 2, so you know t 2, the voltage drop through the secondary coil, is 5 volts.

Our transformer technicians drive us to the forefront of transformer design and manufacturing in the UK. The kVA rating will also be affected by the application of the load, for example motors may need an increased kVA rating.

Totally enclosed non-ventilated:As with single-phase units, these three-phase systems are ideal for environments that contain high volumes of dirt and debris. When you’re doing calculations with three-phase transformers, you’ll need to include a constant to make sure your work comes out correctly.

In the guide to transformer kVA ratings below, we’ll explain in more detail how to calculate the required capacity kVA rating. I bought a 5kva transformer and needed it within 3 days as my other one had stopped working and I had an important task to complete. If you can’t locate the required current flow, you can calculate it by dividing the input voltage by the input resistance. In that case, you’ll probably need to replace your transformer, and when you do, you’ll need to select one with the correct kVA for your needs.
