LINAM AR360 and LINAM AR

Overhead AutoRANGER Fault Indicators

The LINAM AR360 and LINAM AR are self-adjusting fault indicators for overhead lines. They automatically select trip thresholds based on sampled load current and improve system reliability and restoration speed by indicating momentary faults before they become permanent outages. The indicators separately identify permanent and momentary faults using red and amber LEDs and flash patterns. You can apply the AR360 on distribution systems up to 34.5 kV and the AR on systems up to 69 kV.

The AR360 and AR are quick and easy to install with one hot stick. There are no clamps to disassemble. No extra hardware is needed.

Overhead Fault Location—Apply AR360 or AR indicators across your entire overhead system as a single economical solution to reduce fault-finding time and improve reliability metrics. The AutoRANGER logic automatically selects the best trip threshold based on sampled load current and reduces the effort of coordinating fault indicators with various protection schemes. The bright LED display provides high-visibility fault indication, day or night.

Momentary Fault Detection—Improve system reliability by tracking down momentary faults before they become permanent outages. The AR360 and AR are equipped with simple-to-interpret displays that provide distinct flash patterns for permanent and momentary faults.

Distribution Circuit Reliability Improvement—Deploy the AR360 on distribution circuits up to 34.5 kV and the AR on distribution circuits up to 69 kV.

Details

Self-adjusting trip thresholds adjust based on the load current and eliminate the need to specify a trip threshold. This feature reduces engineering time and inventory by allowing you to use one device model across your entire system.
Distinct momentary and permanent fault indications help you locate permanent and momentary faults.
Battery-saving technology maximizes product and battery life with more than 2,500 flash-hours for the AR and more than 1,800 flash-hours for the AR360.
An intelligent energy-saving LED display provides the appropriate level of intensity for ambient lighting conditions.

Patented Ramp-Down Restraint feature prevents false activation after extended circuit lockout and provides trip-threshold memory.
Rugged construction ensures a long product life.
Installation is quick and simple.
- Installs with a single hot stick—no extra clamps or screws.
- Requires zero maintenance.
- Allows testing, activation, and manual clearing with the CRSRTT tool.

Some configurations, such as those with an LED or timed-reset feature, may contain a battery. For configurations with a battery, please see the lithium metal battery warning.
