Test tap
The bushing has a test tap that is connected to the outermost conductive layer of the condenser core. The test
tap is used to measure the bushing insulation by capacitance and dissipation factor. The cover connects the
outermost conductive layer to ground, and must always be installed when the bushing is energized.
The maximum one minute test voltage for this test tap is 20 kV
rms
. The test tap can be used as a power
source, if it is connected to an external capacitance. The operating voltage is limited to 6 kV.
CAUTION!
Do not energize the bushing without a test adapter or the cover installed. The bushing is grounded
through the cover to prevent damage to the bushing.
