Wtat is mean by GHOAST VOLTAGE?..

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.
