Explanation:
heres ur answer
The fragments may cause mechanical damage to nearby Current Transformers, CVTs, Bushing etc. which is much costlier to replace. There is one another reason but most important aspect which demands periodic testing of LAs. LAs protect Transformers, Switchyard Equipment from voltage surge.
