operating mechanism. The base frame shall be ANSI 70 gray painted steel with
phase spacing as shown in the following table.
Maximum kV Rating Phase Spacing (inches)
38, 48.3, or 72.5 48
123, 145, or 170 84
4.03 Support Structure
Each 38 kV through 72.5 kV capacitor switcher shall be provided with a
manufacturer supplied support structure consisting of one hot dipped galvanized
tubular steel 12” x 8” vertical column (mounting pedestal) 46-¾” tall with a 1”
thick base plate measuring 24” x 24” with a 4 hole bolt pattern on 20” x 20”
centers and furnished for use with 1” x 2’-9” “J” type anchor bolts.
Each 123 kV through 170 kV capacitor switcher shall be provided with a
manufacturer supplied support structure consisting of two hot dipped galvanized
tubular steel 12” X 8” vertical columns (mounting pedestals) 83-¼” tall with a 1”
thick base plate measuring 24” x 24” with a 4 hole bolt pattern on 20” x 20”
centers and furnished for use with 1” x 2’-9” “J” type anchor bolts.
Unless otherwise specified in the quotation request anchor bolts will be provided
by the purchaser. All anchor bolts shall be sized as required for the operational
loads generated by the capacitor switcher. The manufacturer shall determine
anchor bolt sizing and anchor bolt plan details when providing the anchor bolts.
5.0 DESIGN TESTS
The capacitor switcher shall be design tested in accordance with ANSI C37.09-2001.
The testing shall include a dielectric test, a power test, a continuous current test, and a
mechanical endurance test. The dielectric test shall include 60 Hz power frequency,
lighting impulse withstand, and visual corona. The power test shall include short circuit
interrupting, fault closing, short time withstand, resistor fault closing, and shunt capacitor
bank switching.
6.0 PRODUCTION TESTS
Each capacitor switcher shall be fully assembled as a three-phase unit at the factory,
adjusted, tested, and timed per ANSI C37.09 section 5. The tests shall include:
6.01 Mechanical Operation Tests
There shall be at least 50 mechanical operations performed at the factory.
Timing tests, opening and closing operations at minimum and maximum
operating voltage, and spring recharge time shall be recorded.
