Answer / meenakshi

Stray or ghost voltages occur from capacitive coupling,
which takes place between energized circuits and non-
energized non-connected adjacent wiring.
practical occurance : When facilities or buildings are
built and wired, it's very common for the electricians to
pull extra wire thru the conduit for future use. These
wires are typically left unconnected until needed.at this
situation coupling effect takes place as explained above.

Answer / anoop

Ghost voltage is the voltage which is occurred due to the
long length of cable (upto 400 mtrs) which generates
induction in the cable. Suppose we use a 16 c X 2.5 Sqmm
cable at a distance of 430 mtrs there will a induction in
ideal cores of cable due to long length of cable. Which is
called the ghost voltage.

We have drive feeding an output contactor for a 5000 hp motor @ 5kV application. The motor FLA is 629amps x 1.25% service factor = 786.25 amps The cable that we current have in place between the drive and the output contactor is 350kcmil- MV-105 (parallel cables). Per the NEC table 310.60 (C) (69). This show the cable ampacity is at 615 amps per cable for a rating of 1230 amps. We have derated the cable for the cable tray and the multiple cables application and our calculations show that after the correction factor factor we are at 922amps. 1230 amps x .75% correction factor factor = 922.5 amps. The customer is driving us to then use another safety factor of .25% off of the already derated cable. Can you please provide a longhand calculation for your solution on this application?
