Figure38. Suggested test circuit for high voltage “shop-testing” solenoid-closing reclosers
Electrical closing – motor-operated
low voltage closing solenoid / auxiliary-powered
NOVA reclosers
WARNING
Hazardous voltage. Solidly ground all equipment.
Failure to comply can result in death, severe personal
injury, and equipment damage. T223.2
High-voltage is not required for reclosers utilizing a
motor-operated closing mechanism, low voltage closing,
or Auxiliary-Powered NOVA recloser. For information on
energizing the recloser, refer to the appropriate recloser
installation manual. Low voltage supply can use either 120
or 240 VAC for input power. Check the name plate on the
recloser to verify the correct closing power requirements.
Figure39 shows a test circuit for motor-operated,
low-voltage solenoid-closing, and Auxiliary-Powered NOVA
reclosers. Since these reclosers require only a low voltage
source for closing, high-voltage transformer T3 and its
protective cage is eliminated. All other equipment is the
same as the test equipment shown in Figure38.
