Closing the recloser during testing
Electrical closing – solenoid-operated reclosers
Line voltage is required for automatic recloser operation during
testing of reclosers equipped with a closing solenoid (except
for reclosers equipped with the low voltage closing accessory).
For on-line testing, bypass the recloser, open the load-side
disconnects and keep the source-side disconnects closed.
This will remove the recloser from service, but will keep line
voltage supplied to the closing solenoid (Figure 38).
For shop testing, the closing solenoid voltage is supplied
by back-feeding a transformer with a low-side rating equal to
the voltage rating of an available power source, and a high-
side rating equal to the voltage rating of the recloser (Figure
40). A 75 kA transformer of the proper voltage rating with
an impedance drop of approximately 3% is satisfactory. The
AC source must have a comparable impedance drop.
WARNING
Hazardous voltage. Interconnect source leads X and Y
and ground solidly to the recloser tank (Figure40).
Do not connect lead Z to any other phase or mechanical
ground. Dangerous voltages to ground exist on
the phase connected to lead Z. Solidly ground all
equipment. Failure to comply can result in severe
personal injury and/or equipment damage.
T224.1
WARNING
Hazardous voltage. The switchgear (apparatus and
control) and high-voltage transformer must be in a test
cage or similar protected area to prevent accidental
contact with the high-voltage parts.
Solidly ground all equipment. Failure to comply
can result in death, severe personal injury, and
equipmentdamage.
T221.5
A test circuit for these solenoid-closed reclosers is shown
in Figure 40. The following equipment is required for the
recommended shop testing setup:
ote:N Solenoid-closed reclosers equipped with a 120- or
240- VAC low-voltage closing coil accessory can be
tested as shown in Figure 41.

Variable Autotransformer T1, 230 Volts, 20 Amps.

Low-Voltage transformer T2 to simulate fault conditions.
Ratio and size will depend upon the maximum current
to be used. The recloser presents a low impedance to
the transformer, so secondary voltage must be only
high enough to force the required current through the
secondary of the transformer and the recloser.
ote:N An alternative method of providing the necessary
current through the transformer is shown in Figure 39.

High-Voltage T3 to operate the closing solenoid.
The closing coil requirement is approximately 200 kVA
during the two-to-three cycle closing operation. The
solenoid coil operating voltage must be maintained at the
recloser bushings during the cycle interval the closing
coil is energized. This procedure is not used on reclosers
equipped with the low-voltage closing accessory.

Ammeter with a rating based on the level of test
current.

Current-actuated timer.
