Patent abstract

A transmission system between a voltage source and a wireline tool comprising a first loop to transmit a signal between the voltage source and the wireline tool. The first loop has a first transformer coupled to the voltage source. The system also comprises a second loop, electrically independent of the first loop, to transmit the signal between the voltage source and the wireline tool. The second loop has a second transformer coupled to the voltage source. If the first loop fails, the first transformer is isolated from the voltage source.
