Overhead Fault Location—Apply AR360 or AR-OH Overhead AutoRANGERs across your entire overhead system as an economical means to reduce fault-finding time and improve reliability metrics. The AutoRANGER logic automatically selects the best trip threshold based on sampled load current and takes the guesswork out of coordinating with various protection schemes. The AR360’s bright LED display provides higher 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-OH are equipped with simple-to-interpret displays that provide distinct flash patterns for both permanent and self-clearing faults.
Distribution Circuits—Deploy the AR360 on distribution circuits up to 34.5 kV and the AR-OH on distribution circuits up to 69 kV.
Six ultrabright, wide-angle LEDs provide overlapping fields of light that collectively yield nearly the same light intensity regardless of the observer's viewing angle. The LED flashing sequence provides a distinctive rotational motion effect that enhances permanent fault display visibility.
Momentary and Permanent Fault Identification
Distinct momentary (amber) and permanent (red and amber) fault indication patterns provide the flexibility of locating the cause of permanent and self-clearing faults.
Auto-Adjusting Trip Threshold Selection
AR360 Fault Indicators dynamically optimize sensitivity and security based on measurements of load. They can detect faults with as little as 50 A of current when loads are light and automatically step up their trip threshold to remain secure for 1200 A loads.
