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.
