Service Requirements
The Kyle Type VCS-1SX switch has been designed with
a minimum mechanical life of 15,000 operations. The
switch requires routine inspection to check for physical
damage and to verify operation.
Frequency of Inspection
Because these switches are applied under widely varying
operation and climatic conditions, service intervals are
best determined by the user based upon actual operating
experience.
High Potential Withstand Testing
Use the following procedures to perform high-potential
withstand tests at 75% of the rated 60 Hz withstand volt-
age for one minute. See Table 4.
Closed Contacts Test
1. Close the switch contacts.
2. Ground the switch.
3. Apply proper test voltage to one of the bushing
terminals. The switch should withstand the test volt-
age for 60 seconds.
Open Contacts Test
1. Open the switch contacts.
2. Ground the switch.
3. Ground the bushing terminal on one side of the switch.
4. Apply proper test voltage to the ungrounded bushing
terminal. The switch should withstand the test voltage
for 60 seconds.
5. Reverse the test and ground connections to the bush-
ing terminals.
6. Apply proper test voltage to the ungrounded bushing
terminal. The switch should withstand the voltage for
60 seconds.
Withstand Test Results
The high potential withstand tests provide information on
the dielectric condition of the switch.
If the switch passes the closed-contacts test and fails the
open-contacts test, the cause is likely to be in the inter-
rupter assembly.
If the switch fails the closed-contacts test, the cause is
likely to be a diminished electrical clearance or failed insu-
lation.
Replacement Parts
Replacement parts for Kyle switches are available
through the factory service department. Only factory
authorized parts are to be used. Contact your Cooper
Power Systems representative for additional information
and ordering procedures.
Factory-Authorized Service
Centers
Factory-authorized service centers are located through-
out North America to provide maintenance, repair and
testing services for Kyle switches. For further information,

WARNING:
Hazardous voltage. The switchgear
and high voltage transformer must be in a test
cage or similar protective device to prevent accidental
contact with high voltage parts. Solidly ground all equip-
ment. Failure to comply can result in death, severe per-
sonal injury, and equipment damage.

CAUTION:
Radiation. At voltages up to the
specified test voltages, the radiation emitted by
the vacuum interrupter is negligible. However, above
these voltages, radiation injurious to personnel can be
emitted. See Service Information S280-90-1, Vacuum
Interrupter Withstand Test Voltage Ratings Information
for further information.
