for the specific kV rating unit requested, and shall allow convenient ground level
access to the control components. 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 circuit switcher. The
manufacturer shall determine anchor bolt sizing and anchor bolt plan details
when providing the anchor bolts.
5.0 DESIGN TESTS
The circuit 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, and short time withstand.
6.0 PRODUCTION TESTS
Each circuit 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
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.
6.02 Leak Test
An SF

leak test shall be performed to confirm the leak rate is less than 0.5% per
year.
6.03 Resistance Tests
6.03.01 Current Path Resistance Test
A terminal-to-terminal micro-ohm resistance check shall be performed on
each interrupter using a 100 A DC source and the values shall be
recorded.
6.03.02 Heater, Coil, and Relay Resistance Test
The resistance of each heater, coil, and relay shall be confirmed to be
within specifications and the value(s) shall be recorded.
6.04 Dielectric Tests
6.04.01 Control Circuit Dielectric Test
The completely assembled and wired operator control circuit shall pass a
dielectric test of 1500 V for 1 minute.
