Sel designs and manufactures fault indicators and sensors supplying utilities around the world with products that help reduce fault finding time so that power can be restored quickly after a fault occurs.

Underground cable fault indicators. If a fault causes a feeder fuse to operate the indicators upstream of the fault trip and the indicators after the fault remain untripped. They are designed for a variety of underground applications and can be paired with a range of display options. Nearby capacitor banks on the overhead system can make outrush worse. This catalog describes features and ordering information for eaton s cooper power series s t a r.

Pathfinder variable trip test point faulted circuit indicators fci which quickly and easily locate faulted sections of underground cable systems. Sel underground autoranger fault indicators are reliable self adjusting settings free faulted circuit indicators suitable for applications with fault current ranging from 50 a to greater than 1 200 a. Underground fault indicators are placed on each primary cable. Line fault indicators consist of a solid state current sensor connected to a faulted circuit display.

Underground faulted circuit indicators specifications trip point 50 a 5 100 a 1 200 a 2 300 a 3 400 a 4 450 a 4 5 500 a 5 600 a 6 800 a 8. Overview of fault indicators. Faulted circuit indicators are attached to underground cable accessories such as 200 a and 600 a elbows and indicate the passage of fault current by showing an orange reflective target in its fisheye display. Faulted circuit indicators can also be installed on cable terminations connected to pad mounted distribution transformers and switchgear.

Sel is the electric power industry s leader in fault indicator technology producing the widest variety of fault indicator products. The utility can easily identify the faulted cable section without a time consuming re fuse. Cabletroll 2300 series fault indicators is a complete system for indication of phase to ground and phase to phase faults in underground 6 36 kv mv cable networks with multi core cables where sensors can be mounted in a safe area on the cable termination. Elastimold underground cable accessories.

Downstream of a fault the stored charge in the cable will rush into the fault possibly tripping fault indicators. Some units will give separate indication for short cir. Fault indicators can be installed on transformers switchgear sectionalizing cabinets bushing terminators overhead lines and underground cable. The cabletroll indicators are fault current detectors for the underground medium voltage distri bution network 6 36kv.
