Page 3: Linetroll 110E/110Eµr Overview
LINETROLL 110Er provides fast fault 1. LINETROLL 110E/110Eµr location enabling reduction in outage times. This represents enhanced service to OVERVIEW the customers thereby improving the utilities image. LINETROLL 110E (110E) is a line mounted fault indicator for local Another important aspect of using fault indication. -

Sensors In order to avoid activating the indicator due to the magnetising inrush current of the line, it's di/dt sensor is blocked for 5 The magnetic field generated by the line sec. upon re-energising of the line. While current induces a signal in the indicator the blocking time elapses, the line current pickup coil. -

4. APPLICATION NOTES The aim of this section is to describe how the LINETROLL 110E indicator behaves in different service situations and network events. 4.1. Energising a healthy line As the magnetising inrush current of a line Figure 6: Delayed reset of flashing. can be very high, the indicator is provided with a 5 seconds blocking which prevents 4.2. -

Defective Transient fault cleared within the last network components may burn or break automatic reclosing, will be detected by the due to the electro-dynamic force of the green LED. The LED will flash for 24 fault current and cause a second fault. -

DIMENSIONS Fix the indicator to the hot-stick and raise/lift it to the line as shown 158 mm in fig 14. Pull the stick downwards and against the line, until the line is in correct position, see fig 15. Release the grip-all stick.

After 2 sec the indicator will respond by flashing the LED’s, see § 10. Flashing sequences -Test/Reset. During the last few months of the battery’s life, an yellow LED with a low flashing frequency (1/10 Hz) will indicate that less than 20% of capacity remains and that Figure 17: Opening/ closing the LINETROLL...

Flashing sequences: Transient fault: Permanent fault: Transient fault followed by a permanent fault Flashing frequency for main flash (red) is 1/3s, 1/10s after 12 hours. For the transient indication (green) the frequency is 1/5s (1/10s after 12 hours).
