You could either:

1: Change the frequency of the phased conductive pipe at the sending (power source) end to an unused number when the machines at the receiving end are not in use.

or

2: Temporarily remove the phased conductive pipe from the sending end of the system until it's needed.

Either option should stop the power drain from your system.
