CapSwitcher
Vertical Interrupter Style Capacitor Switcher
1.0 SCOPE
This specification covers the design, manufacture, and testing of three pole, gang
operated vertical interrupter outdoor capacitor switchers available with or without
integrated transient over-voltage control and inrush current mitigation.
2.0 STANDARDS
All outdoor capacitor switchers shall be designed, manufactured, assembled, and tested
in accordance with the latest applicable ANSI, NEMA, and ASTM standards and
guidelines. If there are any conflicts between the ANSI, NEMA, or ASTM standards and
this specification the specification shall govern.
3.0 DESIGN REQUIREMENTS
3.01 Service Conditions
The capacitor switcher shall be suitable for outdoor installation in electric power
substations under the following conditions:

3.01.01 Temperature
3.01.02 Altitude
3.01.03 Seismic
3.01.04 Wind Loading
3.01.05 Additional Requirements
3.02 Ratings
The capacitor switcher shall perform in an ambient temperature range of
-40oC through +50oC.
The capacitor switcher shall perform at elevations up to 3,300 feet.
The capacitor switcher shall be capable of withstanding seismic loading
of 0.2 g ground acceleration in any direction when installed on the
manufacturer’s furnished support structure and anchor bolts and with
flexible connections to the terminal pads. The device shall perform its
specified functions during and after the seismic event.
The capacitor switcher shall be capable of withstanding wind loads up to
90 mph without loss of function.
If any site-specific service conditions not covered in sections 3.01.01
through 3.01.04 exist (e.g. extreme cold temperature installation,
corrosive environment, high altitude installation, etc.) they will be defined
in the quotation request.
