Product Details
The Cooper Power Systems (Eaton) VFI Vacuum Fault Interrupter Tester is a current injection device designed to simulate Fault Current for verification of minimum trip values and time current characteristics of Tri-Phase and TPG electronic control boards utilized in VFI pad-mounted switchgear.
Three internal flux-shift trippers enable confirmation of the presence of sufficient levels of energy upon the control board for operation of pad-mounted VFI flux-shift trippers. The on-board flux-shift trippers also enable self-checking of the VFI tester prior to general control testing. Further flux-shift tripper capability enables verification of operation of the flux-shift trippers within the VFI unit under test, external to the Cooper VFI tester.
The Cooper Power Systems (Eaton) VFI Vacuum Fault Interrupter Tester has the capability to perform the following operational tests:
- Minimum-Trip Tests
- Time Current Curve Characteristic Tests
- Control Operation Test • Instantaneous Trip Test
- Time-Current Curve Characteristics Modifier
- Limited Testing of SCADA accessory board functions including verification of the minimum trip multiplier function and inrush restraint feature.
- Battery Test
- Flux-Shift Tripper Tests
