AutoLink PortfolioOverview

AutoLink is an electronic sectionalizer, for use on outdoor medium voltage overhead lines.

Single-phase or Three-phase opening for overhead line isolation and protection.

The use of AutoLink in branches, allows better coordination in the event of faults.

This results in a decrease in both operating costs and the number of power outages.

AutoLink Electronic SectionalizerTechnical Information

Tested according to ANSI C37.63

Operates in conjunction with an upstream recloser or recloser switch

Prevents temporary faults from causing unnecessary outages

Detects and discriminates inrush current

Field configurable between 6 and 215A, and from 1 to 4 counts

Independent of time-current curve

Does not require any power sources

Eliminates emission of sparks and fuselink debris during tripping operation, reducing risk of fire


AutoLink Operation

The AutoLink is inactive under normal load conditions.

The electronic circuit senses the current and detects if it is a fault current.

The electronic circuit counts the opening operations of the upstream recloser

When the sectionalizer reaches the preset number of counts (1 to 4 opening operations of the recloser), the AutoLink opens during zero current and it drops open like a standard fuse cutout.

The circuit is reestablished by manual replacement of the tube.

The electronic circuit also performs spectral analysis of the current waveform and discriminates between a transformer inrush current and a fault current.

AutoLink featuresProper Setting

Setting

AutoLink’s actuating current must be set below the recloser’s actuating current

AutoLink’s actuating current must be set between the circuit rated current and the short circuit current

AutoLink’s actuating current must be set 10% below of the fault current of the circuit

AutoLink counts must be set at least one less than the upstream recloser

ExampleA recloser having a minimum trip current of 20 A and 4 trips to lockoutThe sectionalizer immediately downstream from the recloser is then set at 16A with 3 counts to trip

Three-Phase AutoLink ApplicationCoordination with Recloser

A

C

Assume a single permanent line to ground fault occurs on Phase B - (recloser is set to 3 trips to lockout and ABB AutoLink is set at 2 counts)

Recloser performs its first open operationSectionalizer will “count” 1, then recloser will closeRecloser performs its second open operationSectionalizer will “count” 2, then physically the three sectionalizers open before the recloser closes for the second timeThe three phases are isolated
