Wind Farm Favorite—Determine fault location and restore operations in wind farm collector systems. Wind turbine outputs are fed through a transformer and distributed overhead or underground to a collector substation. The voltage will then be stepped up by the collector substation transformer to the utility transmission voltage. A single fault can disable from one to an entire line of turbines. SEL fault indicators help operations personnel quickly determine the location of the fault, isolate the faulted section, and restore the balance of the wind farm. Apply the 3VR Three-Phase Voltage Reset to a 600 A class basic insulating plug that has capacitive test points.
Low Load Current—Install 3VRs where there is insufficient load current to power a current reset fault indicator. These sensors use voltage for power and reset.
