FROM STUDY: It has been seen that intense corona effects are observed at a working voltage of 33 kV or above. Therefore, careful design should be made to avoid corona on the sub-stations or bus-bars rated for 33 kV and higher voltages. i) Sketch and critically analyses about corona effect in 220kV line. i) Sketch and discuss how to minimize the corona in 132kV line.
