Description

The test point reset indicator is a one-piece housing that can be easily installed with a shotgun stick using the pulling-eye. The sensor is designed to minimize proximity effect described as the sensitivity of FCIs to fault currents on other phases of a three-phase installation. The TPR FCI indicates the passage of fault current by showing a “fault” flag in the window of the display. The standard display consists of a highly visible orange fluorescent flag to designate a fault and a black flag to designate a normal condition.The polycarbonate display is made of Lexan® giving the exposed flag window tamperproof and scratch-resistant protection. When the system is re-energized, the indicator resets automatically.

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 (see Figure 4). This unique combination of standard features makes the S.T.A.R. faulted circuit indicator extremely reliable.

manufacturer's commentCooper Power Systems 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. All FCI units are shipped to the customer in the tripped position. The magnetically latched target will not change status as a result of mechanical shock or vibration. After the unit is installed,the energized system will reset the flag from the tripped position to the normal position.
Operating Temperature -40°C to +85°C
Trip Current LevelFactory Preset (High and Low)
Trip Accuracy±10%
Fault Withstand25 kA for 10 cycles per ANSI/IEEE 495-1986
optionsAuxiliary Contacts
Auxiliary contacts can be added to the standard unit and would provide an additional data collection point when used on circuits connected to a SCADA system. The magnetic latchingcircuit that operates the auxiliary contact ensures a reliable indication.
Remote FISHEYE™ Display
The Cooper Power Systems remoteFISHEYE display provides 180°visual indication of FCI operation. This unique orange reflective target fits a standard remote indicator window that exists in many padmount transformer specifications.
Small Remote Display
The Cooper Power Systems’ TPR FCI is also available with a small remote flip-target display. This display can be easily retrofitted for padmount cabinets with a single hole installation.Refer to S320-40-1 for installation details.
