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.
Claims28
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.
A system for transmitting power between a voltage source and a wireline tool, comprising:
- a first transmission loop coupled to the voltage source by way of a first transformer;
- a second transmission loop electrically independent of the first transmission loop and coupled to the voltage source by way of a second transformer;
- and
- a switch, coupled to the first transmission loop, that de-couples the first transformer from said voltage source if said first transmission loop fails.
A method of transmitting power between a power source and a wireline tool, comprising:
- transmitting power over a first transmission loop and over a second transmission loop electrically independent of the first transmission loop, the first transmission loop coupled to the power source by way of a first transformer and the second transmission loop coupled to the power source by way of a second transformer;
- monitoring said transmission loops for failure;
- and
- if said first transmission loop fails, isolating the first transformer from said power source.
A system for transmission between a power source and a wireline tool, comprising:
- first and second transmission loops, the first transmission loop coupled to the power source by way of a first transformer and the second transmission loop coupled to the power source by way of a second transformer, said second transmission loop electrically independent of the first transmission loop;
- means for monitoring said transmission loops for failure;
- and
- means for isolating the first transformer from said power source if said first transmission loop fails.
A computer-readable medium storing computer code which, when executed, causes a processor to perform a method comprising:
- transmitting power over a first transmission loop and over a second transmission loop electrically independent of the first transmission loop, the first transmission loop coupled to the power source by way of a first transformer and the second transmission loop coupled to the power source by way of a second transformer;
- monitoring said transmission loops for failure;
- and
- if said first transmission loop fails, isolating the first transformer from said power source.
