“The camera as an aid to electrical and mechanical testing”

When Mr. Wood worth presented his interesting paper before the Institute last February, it was mentioned that the Victoria Falls and Transvaal Power Co., Ltd., were utilising Mr. Woodworth's scheme for the purpose of the investigation of fault conditions on its Witwatersrand electric power supply system. It was realised that the cinematograph offered possibilities of obtaining fault records which would be of value in verifying the operation of the automatic, devices, the behaviour of generating plant and the performance of switchgear.
