a) In suspension insulator numbers of insulators are connected in series to fom a string and the line conductor is carried by the bottom most insulator. Each insulator of a suspension string is called disc insulator because of their disc like shape. Briefly describe the advantages and disadvantages of suspension insulator used in transmission lines. b) These are mainly THREE (3) main methods generally used for protection against lightning. With aid of illustration, using your own words, explain the concept and drawbacks of cach methods used for substation against lightning. c) Using your own words, briefly describe the concept, drawbacks, and ways to overcome the transient overvoltage in power system network.
