Isolation transformer mainly works as an AC electricity supplier from the power source to the power device. The isolation barrier of this transformer control unexpected power that can harm the appliance or the entire circuit.
Isolation transformer circuit designed with phase, neutral and ground wire connection. Let’s check the Isolation Transformer circuit diagram.
Circuit Diagram of Isolation Transformer
First needs to know the equation of the isolation transformer. We know the secondary winding turns are more significant than the primary winding turns in the step-up transformer, and the step-down transformer is the opposite of this system. But the isolation transformers’ turn numbers are the same on both the primary and secondary sides.
- Step-up transformer: N1 < N2, V1 < V2, and I1 > I2
- Step-down transformer: N1 > N2, V1 > V2, and I1 < I2
- Isolation transformer: N1 = N2, V1 = V2, and I1 = I1
Here is the meaning of N, V, and I are:
- N= The number of turns of the coil
- V= Voltage
- I= Current flow
Isolation Transformer Circuit:
The circuit diagram of the isolation transformer is elementary. Isolation transformer has primary and secondary winding with live, neutral, and ground connections. The inductance and capacitance between the two terminals control the power frequency. The below picture will help you better understand the Isolation Transformer circuit diagram:
Transformers are also used for power supply. Isolation transformers supply power to radio frequency antennas, air-traffic control warning lights, and many others that work not at ground potential.
