SINGLE PHASE vs THREE PHASE vs TRIPLE/SINGLE
SINGLE PHASE Can be Hydraulic or Electronic
THREE PHASE (Gang Operated)
Three-Phase TRIPLE/SINGLE
Triple-Single Mode A: Three phase trip, three phase lockout Mode B: Single phase trip, three phase lockout Mode C: Single phase trip, single phase lockout
RECLOSER DIELECTRIC INSULATION Oil Vs Air Vs Solid Vs SF 6
Oil Dielectric
WE/VWE Closing Coil • Recloser requires voltage from source side for closing • Closing coil connected between bushings 3 & 5 • High voltage closing vs low voltage closing
Air Dielectric
Solid Dielectric
SF 6 Dielectric
Selection Factors • • • System Voltage Maximum Fault Current Maximum Load Current Minimum Fault Current Single Phase or Three Phase
Operation • In single/single mode, pulling down one yellow handle trips and locks out just that unit. • To close, push yellow handle up then hit close button in control. • Non-reclosing will cause just a faulted phase(s) to lockout. • HLT causes all phases to lockout if there is a fault.
Installation • Control runs off AC which needs to be brought into the F 6 control. • Control has a 24 V battery for backup. • Ground the F 6 control cabinet.
If Recloser Fails to Respond • Check “ALARM” functionality for problem information • Inspect for closing voltage • Check control cable connections • Verify yellow handle is up
