LINAM CR

Underground Current Reset Fault Indicator

LINAM CRs can be installed on underground systems. CRs are powered by the load current present on an energized line. A 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 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 CR to primary 200 A-class and 600 A-class URD feeders in any medium-voltage radial distribution circuit. Install the CR on medium-voltage primary underground cable applications or on low-voltage secondary lines in industrial environments. The 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.

Details

  • The CR automatically resets upon restoration of load current.
  • A closed-core design provides adjacent phase immunity.
  • The CR works for single- and three-phase applications.
  • BEACON LED, target, and combination display options are available, depending on your application and operating practices.
  • The CR is ideal for installation in pad-mounted equipment without elbow test points. Install the fault indicator outside of the influence of the ground return path of the concentric neutral of the cable.
  • Installation on low-voltage secondary lines provides an ideal fault-finding solution in industrial environments.
  • The auxiliary contact option provides SCADA compatibility.
  • Fault-powered current reset models are also available for low-load current applications. Please consult SEL.

Some configurations, such as those with an LED or timed-reset feature, may contain a battery. For configurations with a battery, please see the lithium metal battery warning.
