2.2 Scope of Instructions
The instructions are general in nature.
They cover requirements for receiving,
installation, and functional checks as
applied to ADVAC and AMVAC medium
voltage circuit breakers. These instruc-
tions do not attempt to cover all possible
issues that may arise during receiving to
commissioning of breakers.
Information on particular installations
appears in the following:
·Bills of Materials that list electrical
devices and equipment.
·Single line drawings showing power
connections.
·Elementary and schematic
diagrams.
·Connection diagrams
3Inspection, Handling and
Storage
3.1 Inspection
Before shipment, the equipment is
inspected and marked with its rating.
Breakers are shipped in the open and
discharged condition in separate crates.
Upon receipt of the equipment, use the
breaker commissioning check list in the
back of this document to examine the
shipment for damage or missing
components. Follow the procedures
outlined in the next section.
3.2 Handling
Transport breakers upright using proper
lifting equipment. Take the high center of
gravity into account. Carry out loading
operations only when it has been ensured
that all precautionary measures to protect
personnel and materials have been taken
into consideration.
3.3 Storage
For circuit breakers, store upright in their
original shipping carton oriented as
indicated on the shipping crates. See
breaker installation and operation manual
for details on breaker storage.
4Procedures
4.1 Receiving inspection
Inspect shipping crate for damages, and
note condition oftip &tell ifequipped.Check
the contents against the packing list before
discarding any packing material. Check the
consignment for completeness and lack of
any damage (e.g. moisture and its
detrimental effects). In case of doubt, the
packing must be opened and then properly
resealed, when intermediate storage is
necessary. If any quantities are short, or
defects or transport damage is noted, these
must be documented on the respective
shipping document. Notify ABB and the
carrier at once of any discrepancies. If there
is damage from improper handling, file a
claim for damages at once with the carrier
and notify ABB.

4.3 Functional Test
For operation, component identification and
locations refer to the breaker IB provided
with the breaker. ADVAC breakers refer to
IB 1VAL050503-MB, AMVAC breakersrefer
to IB 1VAL050601-MB.
With the circuit breaker either on the floor
or on a suitable work surface. Use the
breaker IB and the commissioning
checklist in the back of this document to
record any deficiencies.
Check breaker truck:
a. Truck handles move inward
with little resistance and
spring back outward (Figure
4.10).
b. Racking screw release lever
moves down with little
resistance and returns up
when released (Figure 4.8).
c. Wheels are parallel with truck
and rotate freely.
Figure 4.13 Truck wheel
Check breaker manual operation:
a. Perform a manual charge
insuring that charge indicator
changes state.
b. Perform a manual close
operation. (ADVAC only) And
insure closed indicator is
shown.
c. Perform a manual open
operation. (ADVAC only) Note
if there are any deficiencies
during the operations.
Check the breaker’s secondary power
requirements listed on the front label and
insure that the breaker is of the correct
control power of the supplying equipment
for the following tests (Figure 4.1).
Apply power to the breaker using a breaker
test cabinet (Figure 4.14) or a Switchgear
umbilical cable.

4.4 PrimaryCircuit Test
The primary circuit of the breaker has been
tested prior to shipment. Retesting prior to
energization will insure no internal
transportation damages have occurred.
Verification of vacuumcan be performed by
a low-frequency AC withstand test.
Additional a contact resistance testl by
performing a contact resistance test is
recommended.

Figure 4.15 Primary low-frequency withstand test
voltages
To verify the integrity of the vacuum
interrupters perform the following low-
frequency withstand voltage test:
1. Open the breaker (no control power
supplied to breaker)
a. Connect the high potential lead to
one terminal.
b. Ground the remaining 5 terminals
and breaker frame.
2. Start machine with output potential at 0
(zero) VAC
3. Increase the potential to the required
voltage (Figure 4.15)
4. Hold for one minute
5. Decrease potential to 0 (zero) and turn
off machine
6. Repeat for the remaining 5 terminals
A successful withstand indicates
satisfactory vacuum integrity. Remove
power from the breaker.
Contact resistance is measure at the factory
according to the ANSI 37.09 using a 200A
µohm meter. This DC resistance test should
be performed after each fault the primary
circuit, from terminal to terminal of each
pole unit, in the close position shall be
measured with at least 100 A of dc current
flowing in the circuit and shall not exceed
the limit set for the rating of the circuit
breaker by the manufacturer.
Remove lifting angles from breaker.
Note: Breaker will not fully rack in with lifting
angles installed.
CAUTION
High voltage applied across
an open gap in a vacuum can
produce X-radiation. When
the breaker is fully open the
contact spacing is such that
when tested with the voltages
specified, X-radiation at one
meter is below the level of
concern. A danger could
exist at voltages above the
dielectric test voltage or
reduced contact spacing
caused by a major internal
mechanical failure of the
breaker.
