Abstract

A method is provided for reducing the stray noise associated with the transmission of the electrical power between a power source and a target. The method includes the step of interconnecting the power source and the target with a conductor. A shield is positioned about the conductor to prevent electromagnetic and radio frequency interference from passing therethrough. A low impedance path is provided for the stray noise to travel between a neutral point of the power source and the isolated target.

Claims

1. A method to reduce stray noise associated with the transmission of electrical power between a power source and a target, comprising the steps:

providing a conduit having a conductor;

interconnecting the power source and the target with the conductor;

positioning a shield about the conductor to prevent electromagnetic and radio frequency interference from passing therethrough;

mounting connectors on opposite ends of the shield for interconnecting a first end of the conduit to the power source and a second end of the conduit to the target; and

providing a low impedance path for the stray noise between a neutral point in the power source and the target.

2. The method of claim 1 comprising the additional step of isolating the target from ground.

3. The method of claim 1 further comprising the additional step of interconnecting the neutral point of the power source to ground.

4. The method of claim 3 wherein the target includes a grounding block and wherein the method includes the additional step of interconnecting the grounding block of the target and the neutral point of the power source with a ground wire.

5. The method of claim 1 wherein the step of providing a low impedance path includes the steps of:

wrapping wire braiding about the shield, the wire braiding having first and second ends;

interconnecting a first end of the wire braiding to the target; and

interconnecting a second end of the wire braiding to the neutral point of the power source.

6. A method to reduce stray noise associated with the transmission of electrical power between a power source and a target, comprising the steps of:

isolating the target from ground;

providing a conduit including;

a conductor for electrically connecting the power source and the target;

a tubular core extending about the conductor and having an outer surface;

braiding wound about the outer surface of the core, the braiding having first and second opposite ends; and

a flexible outer jacket extending about the braiding, the outer jacket including first and second ends;

mounting connectors on the core adjacent corresponding ends of the outer jacket;

interconnecting a first end of the conductor to the power source and a second end of the conductor to the target; and

interconnecting the first end of the braiding to a neutral point of the power source and the second end of the braiding to a grounding block on the target.

7. The method of claim 6 further comprising the additional step of interconnecting the neutral point of the power source to ground.

8. The method of claim 6 wherein the method includes the additional step ofinterconnecting the grounding block of the target and the neutral point of the power source with a ground wire.

9. The method of claim 8 comprising the additional step of wrapping the ground wire around the conductor.

10. The method of claim 8 comprising the additional step of positioning the ground wire adjacent the conductor along the length thereof.

11. The method of claim 6 comprising the additional steps of:

providing the braiding with first and second end portions; and

extending the end portions through the outer jacket of the conduit.

12. A method to reduce stray noise associated with the transmission of electrical power between a power source and a target, comprising the steps:

interconnecting the power source and the target with a conductor such that the electrical power is transmitted thereon;

positioning a shield about the conductor to prevent electromagnetic and radio frequency interference from passing therethrough;

transmitting electrical power from the power source to the target on the conductor; and

providing a low impedance path to a neutral point of the power source for the stray noise associated with the transmission of the electrical power, the low impedance path formed by;

wrapping wire braiding about the shield, the wire braiding having first and second ends;

interconnecting a first end of the wire braiding to the target;

interconnecting a second end of the wire braiding to the neutral point of the power source; and

mounting connectors on opposite ends of the shield for connecting the shield to the power source and the target.

13. The method of claim 12 comprising the additional step of isolating the target from ground.

14. The method of claim 12 further comprising the additional step of interconnecting the neutral point of the power source to ground.

15. The method of claim 12 wherein the target includes a grounding block and wherein the method includes the additional step of interconnecting the grounding block of the target and the neutral point of the power source with a ground wire.

16. The method of claim 15 comprising the additional step of wrapping the ground wire around the conductor.
