Isolation Transformer Voltage

Isolation Transformer Voltage Study

We will study Isolation Transformer voltage in this article. Michael Faraday invented the transformer in 1831. After a long time, in 1886, William Stanley made a commercial transformer. For many of them, the isolation transformer is one. Basically, it uses to maintain voltage levels between primary and secondary terminals.

The transformer is designed to transmit AC from one terminal to another terminal without changing voltage, power, frequency, or other things. It works on the principle of EMF (electromagnetic force) induction.

Understanding Isolation Transformer Voltage

An isolation transformer is a device that transmits AC from one terminal to another terminal with the same level of voltage, current, and frequency. This transformer’s primary and secondary windings turn number is the same, and it also sustains the same power, voltage, and current. Isolation Transformer low voltage (3.3 to 24 V) supplies up to 7.2 Watts isolated DC-DC power.

Difference Between Primary and Secondary Terminal

What is the difference between the primary and secondary terminals in the Isolation Transformer? Well, let’s get started. Isolation transformer’s primary and secondary windings turn numbers are the same. The turn ratio between the terminal is Np: Ns =1.

The transformer is used to receive step-up and step-down current—isolation transformer used in high voltage transmission line. Isolation transformers have sustained the same voltage level between primary and secondary terminals. An isolation transformer is also called a 1:1 ratio transformer.

Isolation Transformer Voltage Measurement

Isolation transformer used in safety issues. If the voltage in the primary terminal unexpectedly rises, it may damage the secondary terminals substation equipment. For stoping this from happening, an isolation transformer connected a transmission line between the primary and secondary terminals. It hampers to transmit the extra rising voltage to the secondary terminals.

Assume, primary terminal’s current rises to 200A. The secondary terminal flows it 5A of the step-down process through an isolation transformer because primary and secondary turns numbers are equal both the site.

Ep(volts) Es(volts) = NpNs

Ep= Primary voltage.
Es= Secondary voltage.
Np= number of turns in the primary terminal.
Ns= number of turns in the second terminal.

Note : NpNs=a, EpEs=a, the transformation ratio is, a : a =1:1

It is very important to control voltage levels in the transmission line. An isolation transformer helps to sustain the level. So, the transformer is very efficient for the power generation and distribution system.
