We know transformers are used to up or down the voltage and the current between the primary and secondary windings. There is a change between the primary and secondary windings of the transformer, which up or down the current or voltage. But in an isolation transformer, there is no difference between the primary and the secondary windings. It passes the same voltage, same current to the output. The question may arise in your mind then what is the use of it. This blog will describe the uses of the transformer below:
A Little Information About the Isolation Transformer
An isolation transformer is called the 1:1 equational transformer. Assume, the primary windings are Np, and the secondary windings are Ns. Then the relation of Np and Ns is Np=Ns. On the other hand, the primary voltage is Vp, and the secondary voltage is Vs. Then the relation between Vp and Vs. is Vp=Vs.
Uses of the Isolation Transformer
An isolation transformer uses for various purposes for safety issues. It saves the electrical devices from the AC source’s unwanted low or high level of current and voltage. Computer, oscilloscopes, medical devices, and some other critical electronic devices use the isolation transformer. Some important uses of isolation transformers are given below:
- Electric motor stater
- Electrical and electronic testing devices
- Circuit and rudders communication
- Stopping ground loop interference in a circuit
- Reduce electrical noise
- Reduce electrical losses
- Protect from electrical shock
Another use of isolation transformer is Pulse transformer. The windings of the isolation transformer are not connected to any physical wire. It transmits the power and voltage to the output side by the EMF. It saves the devices from the unexpected high voltage or current flow.
