LineTroll 110Eμr Fault Passage Indicator for overhead lines (6-69 [kV])

Product Nr.: 04-1200-05

A cluster of red LED's for permanent fault and one green LED for transient fault. In addition a single LED will give indication on low battery status. High visibility.

Features:

• Programmable operating parameters.
• High visibility ( > 12 lumens) 360 degrees.
• Usable on all Medium Voltage distribution networks 6-69 [kV].
• Usable on multi circuit systems.
• Voltage or current as start criteria (programmable) = inrush blocking.
• Dual indication, permanent and transient faults.
• Resistant to tough weather conditions.
• Battery capacity monitoring.

Functional description:

LineTroll 110Eμ continuously monitors the line voltage and phase current, the sources of information it needs to operate. The unit is fully self-contained, no external transformers or connections is required. During normal line conditions, LineTroll 110Eμ remains extinguished.

The indicator is looking for a specific sequence of line conditions to happen before it starts flashing. The general sequence is as follows:

A. The line should be energised (voltage or current present) for a minimum of 5 seconds.

B. Di/Dt : The line current should increase rapidly by the amount of a user set value (the step level). Treshold, the line current exceeding a present current level.

C. The line should be de-energised. (Voltage or current not present).

The user may program the criteria for operation to suit his local requirements by manipulating a bank of micro-switches inside the indicator.

Note: Voltage or current as start and stop criteria is user programmable.
