Portable Solar Batteries for Electric Power Supply to a Device for a Cable Fault Location

The results of the studies on the development of a portable solar battery for electric power supply to a portable device for locating a cable fault and the position of pipelines in the ground (CFL-3) are reported. The CFL-3 device is developed as two blocks: an oscillator and receiver with intrinsic autonomous solar batteries. The structure and photovoltaic characteristics of the solar batteries under full-scale operating conditions and the CFL-3 technical characteristics when operating with solar batteries are given.
