1. 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, said first loop having a first transformer coupled to said voltage source; and
a second loop, electrically independent of the first loop, to transmit the signal between the voltage source and the wireline tool, said second loop having a second transformer coupled to said voltage source;
wherein, if the first loop fails, the first transformer is isolated from the voltage source.

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.
