Eaton's Cooper Power series S.T.A.R. Test Point Reset (TPR) faulted circuit indicators are designed to quickly and easily locate faulted sections of underground cable systems. These faulted circuit indicators (FCIs) can be used on both 200 A separable connectors and 600 A terminators with a voltage test point. The removable sleeve allows for use on major manufacturers’ loadbreak elbows. S.T.A.R. TPR FCIs feature a stored energy design that utilizes the capacitively coupled voltage present at the elbow test point. This design ensures fast, reliable and accurate operation.

Design Features

  • An inrush restraint feature eliminates false tripping and is standard on all units. The S.T.A.R. faulted circuit indicator will ignore inrush currents caused by reclosing operations of protective devices on the system. A dead time of 200 ms will activate the inrush restraint feature.
  • A low pass filter, also a standard feature, will prevent the S.T.A.R. faulted circuit indicator from tripping on high frequency transients like those caused by cable capacitive discharges.

  • In addition, the S.T.A.R. faulted circuit indicator is equipped with temperature compensation circuitry to assure accurate reliable performance over the entire specified temperature range.

  • The quick response time of the S.T.A.R. test point reset faulted circuit indicator allows easy coordination with currentlimiting fuses. This unique combination of standard features makes the S.T.A.R. faulted circuit indicator extremely reliable.
