Abstract
An Integrated Power and Signal Transmission System A system is described which links by means of a pair of lines the command signals in square waveform from a unit broadcasting such command signals to an operating unit lying a long distance sway so that since the signals are sent at a low voltage of about 36 V and a frequency of about 1 kHz, they are enough after being stored in top quality capacitors to provide power to the operating point at said operating unit, without there being any need to stop power supply when signals are being sent, as used to happen in the previous system. Such system is particularly suitable for the transmiting of operating signals and the receiving of information from a wellhead.
