Page 5: Section C: Operation Of The Autolink
1YSA160003-EN - Rev. 5 5 / 19 Section C: Operation of the AutoLink C.1. General The AutoLink Electronic Sectionalizer is a protection device that operates at a permanent fault in the distribution line. It must be used together with an upstream recloser or circuit breaker with reclosure capability. Please take note that the AutoLink is not a fuse tripping device, therefore it cannot be used as a protection device by itself. -
Page 6: Operating Under Permanent Fault Conditions
1YSA160003-EN - Rev. 5 6 / 19 Figure 2. C.2.2. Operating Under Permanent Fault Conditions The remaining 10-20% of faults in distribution overhead lines are considered permanent. During these faults, the continuous cycling of the recloser does not clear the fault. .The AutoLink will pickup, measure zero current and count, reaching its trip count setting. The AutoLink will trip on the last open cycle of the recloser, isolating the permanent fault in its branch and allowing the recloser to close prior to going to lockout and maintain power to the unaffected branches. -
Page 7: Minimum Autoreclosing Operating Time Required For Autolink Operation
1YSA160003-EN - Rev. 5 7 / 19 Minimum Current - Time Requirement Current [A] Figure 4. C.4. Minimum Autoreclosing Operating Time required for AutoLink operation The AutoLink requires a line current greater than 5 A in order to be fully charged during at least 15 seconds. After the condition of the device is fully charged the line current can vary as low as 3A and it will continue to be operative. -

Mounting the AutoLinks in the three phase body For each AutoLink place the hookstick in the tube’s lower contact eyelet and mount in the isolating support body. Figure 17. Withdraw the pole and place it in the tube’s superior eyelet (See Figure 10). Push it until it remains in closing position. Figure 18. -
Page 17: Commissioning
1YSA160003-EN - Rev. 5 17 / 19 D.5. Commissioning D.5.1. General procedures When commissioning, all operations must be carried out by suitable qualified customer personnel with in-depth knowledge of the apparatus and the installation itself. It is not recommended to open AutoLink under charge using a common hookstick, as it could cause an arc that might damage the personnel or the equipment. -
Page 18: Section E: Maintenance
- Check the upper contact cap is correctly fastened and both the o-ring and the silicon grease are present. Test should be carried out on a laboratory with the appropriate equipment to simulate service conditions. For this operation it is recommended to contact ABB to request the testing procedure. - Page 19 Valentin Alsina (B1822CJU) Buenos Aires. Argentina.
