L-T Isolation Transformer
L-T Isolation Transformer
Operation
Isolation transformers are a type of transformer, designed to have primary input and secondary output windings. Both these windings are separated with the help of an electric insulation barrier. Therefore, in case of any fault, the power is not transferred to next stage.
We know that switching of electrical equipment in commercial spaces breeds spikes up to 10000 Volts & high-frequency Noises. It disturbs the sine-wave output, causing the failure of Microprocessors, thrusters, or other sensitive electronic devices.
