F5814 Recloser Interface Unit ® Typically reclosers are installed on electric utility poles closer to the power conductors while the recloser controller is located on the same pole closer to the ground. The controller is connected to the recloser via a control cable. These control cables can have various configurations such as 14, 19, 26 or 32 pins. The F5814 supports a 14 pin cabled recloser. Typical Recloser installation Recloser The use of F5814 results in an effective and efficient testing of 14 pin reclosers. In addition, the use of ProTesT macros to provide test voltages and currents yields repeatable results and a standardized test plan. Also, the report generating feature of ProTesT allows easy documentation of the test parameters and results. Recloser Controller 14 Pin Control Cable

Typical pin designations of a 14 pin control cable are as follows: A B C L M D E K P J N F H G A 24V dc B Monitored Trip Circuit Point C Trip D Monitored Trip Circuit Point E Close F Monitored Close Circuit Point G Terminal I1 Current H Terminal I2 Current J Terminal I3 Current K Residual Current Return L Not used M Recloser Ground N Not Used P Not Used The control cable brings in the three secondary phase and neutral currents from the Cts located in the recloser to the recloser controller. These secondary currents are carried by pins G, H, J, and K. Pins C and E carry the trip signals from the...

In this mode, the recloser is out of the circuit and hence the trip and close coils which are located in the recloser have to be simulated and this simulation is performed in the F5814. These simulated coils located in the F5814 react to the 24 Vdc that is provided by the recloser controller via the 14 pin control cable. The currents, which under normal operation, are fed by the CTs located at the recloser, are supplied by F6150 via F5814 during the test. The trip signals received by F5814 from the recloser controller are passed on to the logic inputs on the F6150. Hence, the F6150 supplies controlled...

LEDs to display the 52a and 52b states are provided and signal monitoring terminals provide signal access to digital voltage meters or oscilloscope. RECLOSER TEST INTERFACE UNIT fcOUlPMtNT USING For more information, contact Doble Engineering Company Doble is an ESC0 Technologies Company
