Installation of Current
Transformer Barrier Figure 42 - Current Transformer Barrier
Hi-Pot and Megger Test Insulation integrity should be checked before energizing medium voltage
electrical equipment. Use a high voltage AC insulation tester or a Megger for this
test. If a Megger is used, a 5000 volt type is recommended.
ATTENTION: Ensure current transformer barrier is installed before
re-energizing the equipment. Failure to do so may result in electrical faults and
cause damage to equipment or serious injury to personnel.

ATTENTION: Exercise caution when performing high voltage tests on the
equipment. Failure to do so may result in electric shock causing severe burns,
injury or death
ATTENTION: Disconnect power factor correction capacitors (if so equipped)
before performing the Hi-Pot test. Failure to do so may result in personal injury
or damage to the equipment. See Power Lock-out Procedure (refer to
Power
Lock-out Procedure on page 47 of Chapter 5 ) for information on dissipating any
stored power in the capacitors.
