This transformer uses the real cable otherwise bus-bar of the major network like the primary winding, which is equal to an only twist. We hope that you might have gained some valuable insights and concepts out of this transformer article, after thoroughly reading it. PORTB pins RB2-RB7 are used and these lines declare pins. PWMx_Init(long frequency) function used to set/declare frequency of signal. Similarly, if a signal stays high for a longer period of time than it stays low, the signal will have a duty cycle greater than 50%. The main purpose of this transformer is to isolate securely the secondary winding once the primary winding has high voltage & current supply so that the energy meters, relays, or measuring instruments are allied toward the secondary winding of the transformer which will not get injured.
