Step 1

Type of Transformer

First, you will need to decide what type of transformer you will need. Often this is decided by your environment, specs, and application. For example:

  • Are you dealing with high voltage?
  • Do you need isolation?
  • Do you need noise attenuation?
  • Do you need rectification?
  • Is this for a furnace?
  • Are you dealing with pulses?

These types of questions can help start you on the path to knowing what type of transformer you may need. We can help you spec a transformer out by either calling or emailing us, or you can discover on your own the best possible solution for you by visiting our product pages.

Step 2

Voltages

The first thing we will do is ask you what the incoming and outgoing voltages will be (often referred to as the primary and secondary voltages, respectively). These voltages can range from 1 V up to 300,000 volts depending on your application. These voltages are one-step in dictating the type of transformer you will need.

***Note: In a ground transformer (zigzag transformer) there is not a secondary, as the secondary acts as a ground.

Step 3

Current

The next thing we will ask you is for the current of the secondary voltage. This information will help us calculate the power rating of your transformer or assembly. This is important as the current can play equal parts to, or a more important, in your needs. Furthermore, understanding your current needs will help dictate the type of transformer required as well as the type of terminations options we can accommodate.

Step 4

Frequency

Next, we will ask you for the frequency of the transformer. This is important information to have as it will dictate the size (and our capabilities) in building the transformer. Frequencies of 50/60 Hz are most common. We also build to frequencies ranging from 400 Hz up to 20,000 Hz. Furthermore, pulse is an important factor. If you do have pulse requirements, please do let us know as this will heavily impact the design of the transformer.

How to Order

What You'll Need

Our engineers are well-versed and knowledgable and will be able to help guid you through the design and spec'ing process. However, even they will need to know a few parameters before they can design your transformer. Below is a list of the things they will need to know in order to design your Interphase Transformer:

  • Nominal voltage (required)
  • Current (required)
  • Current overload
  • Current imbalance

If you do not know how to necessarily spec out a transformer, or need more information, we have many ways of helping you figure it out. To start, check out our Resources Center. If that doesn't help, contact us at the phone number or email address above. One of our Technical Assistants and Engineers will be more than happy to assist you.
