Acceptance and initial inspection
Each capacitor switch is completely assembled, inspected,
tested, and adjusted at the factory. It is in good condition
when accepted by the carrier for shipment. Upon receipt of
a capacitor switch, inspect the capacitor switch thoroughly
for damage and loss of parts incurred during shipment. If
damage or loss is discovered, file a claim with the carrier
immediately.
Handling and storage
If the capacitor switch is to be stored for an appreciable
time before installation, provide a clean, dry storage area.
Locate the capacitor switch so as to minimize the possibility
of mechanical damage.
When transporting or storing the switch, the contacts
should be kept in the closed position to avoid damage to
the vacuum bottle contacts.
Standards
TriSync capacitor switches are designed and tested in
accordance with IEEE Std C37.66™ standard.

Description of operation
The TriSync vacuum capacitor switch is a Three phase,
Solenoid-operated vacuum switch. The solid polymer
insulation system does not rely on gas, foam, or liquid
dielectrics. Highly resistant to ozone, oxygen, moisture,
contamination, and ultraviolet light, it is an environmentally
safe capacitor switch. The TriSync capacitor switch has
polymer bushings and is suitable for operation through a
temperature range as shown in Table 1.
