Sel Cable Fault Indicator

In the years since we have grown and developed a complete line of products and services for the protection monitoring control automation and metering of electric power systems.

Sel cable fault indicator.

The sel cr is ideal for installation in pad mounted equipment without elbow test points. Installation on low voltage secondary lines provides an ideal fault finding solution in industrial environments. It replaces the protective cap on capacitive test points acting as the new cap with the added benefit of providing fault indication. Test and reset tools for fault indicators.

The ar urd uses sel autoranger technology to automatically configure a trip threshold based on the magnitude of the load current flowing in the conductor. Sel tpr underground test point reset fault indicator underground cable fault indicator installation made simple fast fault location leads line crews straight to the fault and reduces the outage duration. Paper insulated lead cable pilc fault indicator find faults faster on paper insulated lead cable pilc. If a fault causes a feeder fuse to operate the indicators upstream of the fault trip and the indicators after the fault remain.

Submersible separable core current transformer. Sel introduced the world s first digital relay in 1984 revolutionizing the power protection industry by offering fault locating and other features for a fraction of the cost of earlier systems. Compact self contained and line powered design eliminates cable neutral positioning concerns. Test and reset tools for fault indicators.

The sel underground autoranger fault indicator ar urd is an underground fci that helps alleviate the challenges of applying fcis with fixed trip ratings. Underground paper insulated lead covered cable fault indicator. Install the fault indicator outside of the influence of the ground return path of the cable s concentric neutral. Fiber optic adapter for sel 300 series relays.

The sel pilc fault indicator fits on 2 2 to 4 64 diameter single phase triplexed and three phase sector or round pilcs. Sel provides complete power system protection control monitoring automation and integration for utilities and industries worldwide. Fault indicators and sensors find faults faster with sel fault indicators and sensors making electric power safer more reliable and more economical underground fault indicators are placed on each primary cable. The sel tpr is an underground faulted circuit indicator fci that attaches to capacitive test points in single or three phase systems.

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.
