Page 30 • Fault directionality Fault Locator The M-7679 R-PAC Fault Locator feature can reduce the time required to restore service due to a distribution system fault by providing an accurate estimate of the fault’s location, even during periods of high customer load.
Page 31 M‑7679 R‑PAC – Specification Recloser/Breaker Wear Monitor The M-7679 R-PAC control records the amount of current carried in each phase each time the recloser trips. The control’s operational logic employs an algorithm integrating the amount of unfiltered AC current at the time of each trip and the number of operations (close to open) as a method of calculating wear.
Page 32 The S-7600 IPScom Communications Software enables local or remote communication between a Windows ® based computer and the M-7679 R-PAC. It is a Windows application, which allows the user to interact with software modules in different languages. The S-7600 IPScom Communications Software makes efficient use of object-oriented programming, achieving a smooth and scalable design, and has an open data structure that allows maintenance and the incorporation of new functions.
Page 33 The M-7679 R-PAC provides a choice of two main power supply input ranges: a low voltage range of 18 to 60 Vdc and a high range of 90 to 280 Vac or 90 to 315 Vdc. The M-7679 R-PAC also features a backup power supply input of 11 to 14 Vdc, that allows continued operation in case of main power supply loss.

I2/I1 is a relatively constant value for any load variation on three phases. However, when there is a broken conductor, this ratio increases very quickly.
Page 139: 47 Negative-Sequence Overvoltage
System Application & Function Setpoints – 3 47 NEGATIVE-SEQUENCE OVERVOLTAGE The Negative-Sequence Overvoltage function provides protection for voltage unbalance and reverse phase sequence.

M‑7679 R‑PAC Instruction Book 50BF BREAKER FAILURE NOTE: The term breaker is used interchangeably with recloser. The control closes an output contact to trip the recloser when it detects a fault or other abnormal condition. Breaker failure protection provides another level of protection should the recloser fail to open. For example the control can send a direct transfer trip command to the first upstream switch that can break fault current should the recloser fail.
