HIGH TENSION LINES
MINIMISING DANGER FROM FALL Br Telegraph.—Press Association Hamilton, January 18. A device for minimising the danger from fallen electric wires was demonstrated by the Central Electric Power Board. A short length of fence five miles away was "livened,” by being connected with a 3000-volt line, and the slight leakage of the current from the fence to the ground was sufficient to operate a circuit breaker at the substation within a couple of seconds, and cut off the power from that area. Six of the devices, which are the invention of the board’s engineer, Air. J. R. Ellis, have been installed, and protect all the 3000-volt lines in the board’s district. Owing to the larger leakage of current, 11,000-volt lines can be protected more easily. The advantages of the new installation are its almost negligible cost nnd the small leakage of current ’’ceded to operate it.
