SPARKING INSULATORS
Sir,—Last evening, which was damp and foggy, I was strolling up a .country road and suddenly my attention was attracted by a buzzing noise. I stopped and listened, and discovered that the noise was being caused by the insulators on a nearby power pole, carrying a high voltage. From the foot of the pole I could see quite plainly a series of sparks surrounding the insulators. Is this normal, or are the insulators faulty?—Yours, etc., SPARKS. Lihcoln, September 24, 1947. [The general manager of the Municipal Electricity Department, Mr E. Hitchcock, said yesterday that the insulators on the high tension line might be in quite good condition, but in certain conditions of fog the damp coating on them might result in a slight electrical discharge. This would account for the buzzing heard by the correspondent. It might be remedied automatically when the insulators were dried by the sun or washed by rain. It might also happen to be a fault condition.]
