We are installing a water jet system in the welder industrial shop, the system is a
30 hp motor starter 460 VAC, 3PH, 60A, 60 HZ, the wiring include 3 hot and a Ground
base on the area of installation, Noise sources may include welders, dielectric heaters, large current switching devices
and RF transmitters.
what would be the best way to suppress unusually high electrical noise or Harmonics in the system?

I do not understand your original post or the response.

First, consider the water jet machine as a stand alone system. It should have been designed such that it does not create any self noise or interference that would cause it to interfere with itself. This assumes no external communication such as RS232.

It is not clear whether your supply is three phase delta with an EGC (Equipment Grounding Conductor), or a three phase wye with no EGC.

Second, are you concerned that some of the other equipment in the shop will cause a malfunction of the water jet, and therefore is there a best way to wire the water jet. Again assuming no external communication to the water jet.

Third, external communication to the water jet has its own considerations.

Conduct a power quality study over time to understand the existing installation for harmonics and dynamic current behavior. This is done in the context of the new equipment requirements, and if not explicitly specified, get manufacturer approval after joint review of the study.

One example would be a FLUKE 1735 3 Phase Power Logger. The test equipment selected depends on the industrial setting.
