mpparent, Laplacian, waross,
Thanks for some of your gray matter.
Mpparent,
NETA - Looking for this now.
Laplacian,
None of the piping is underground. All overhead.
waross,

This chiller plant has 3 X 500 Ton Trane Centrifugal chillers with 4160 vac compressors. Each end of the chiller condensers, compressor motors, pump motors and fan motors are grounded with straps to a common ground grid. The pump and fan motors for cooling towers are 480 VAC.

rbyrne15,
Thanks for your expertise. Will discuss this with the paper mill electricans and electrical engineers. They did not know how to perform this test.
Thank you again.

waross,
Thanks for asking. I have been in industrial water treatment 26 years and have never seen pitting corrosion so rapid and with severity in which I have encountered. I have elemined all the possibilities except for a possible electrical current leak from a chiller motor, pump motor or...
Can any one give the test procedure for testing for current leaks. This is 4160 voltage and may be causing corrosion in chiller condenser. Each condenser is grounded on each end.
