SEL-CRs can be installed on underground systems. SEL-CRs are powered by the load current present on an energized line. An SEL-CR will respond to a fault and remain in the faulted-display condition until the line is energized with normal line load; at which time, it will automatically reset.
UV-stabilized housings, stainless steel, and vinyl-coated clamping mechanisms make SEL-CRs suitable for use in the harsh environments of underground applications.
Years of Maintenance-Free Operation—Apply this energy-harvesting fault indicator in pad-mounted and underground distribution equipment without elbow test points.
Ideal Fault-Finding Solution—Apply the SEL-CR to primary 200 A-class and 600 A-class URD feeders in any medium-voltage radial distribution circuit. Install the SEL-CR on medium-voltage primary underground cable applications or on low-voltage secondary lines in industrial environments. The SEL-CR automatically resets upon restoration of load current.
Time Savings and Safety—Use remote display options, such as the RadioRANGER Underground Wireless Fault Indication System, to eliminate the need to open a pad-mounted or subsurface enclosure to determine fault status.
Report Back to SCADA—Choose the auxiliary contact option for SCADA compatibility.
