ARCO 400 Overview | Universal Recloser Control Testing

Welcome to this overview of the ARCO 400, a universal test set designed to simplify and speed up recloser control testing in the field. In this presentation, we introduce the role of reclosers and sectionalizers in distribution systems, explain the signals exchanged between the controller and circuit breaker, and show why complete testing is essential for reliable operation. We also compare controller testing with traditional relay testing, highlight the advantages of the ARCO 400 for outdoor applications, and walk through its smart adapter ecosystem, software workflow, and advanced testing capabilities. Topics covered in this video include: • What a recloser is and how it works • Recloser vs. sectionalizer differences • Typical pole-mounted and pad-mounted applications • Why reclosers are widely used in distribution networks • Controller testing principles and signal interfaces • ARCO 400 hardware overview and field-ready design • Smart adapters, BOB2, and ISIO 200 accessories • ARCO Control and ReCoPlan software workflow • Distribution automation and DER protection testing The ARCO 400 brings a plug-and-play, rugged, and flexible approach to recloser testing, helping engineers and technicians complete testing faster, safer, and with greater confidence. 00:00 Introduction – ARCO 400 01:55 Typical Recloser Setup 03:22 Recloser vs Sectionalizer 04:18 Pole-Mounted Recloser 05:15 Pole-Mounted Sectionalizer 06:12 Pad-Mounted Recloser 06:53 Why Reclosers? 07:51 Application Example (Recloser + Sectionalizer Scheme) 09:18 Controller vs Relay Testing 10:13 Controller Testing Approach 10:58 ARCO 400 Hardware Overview 12:44 Outdoor Design & Ruggedness 13:46 Plug & Play connection 14:30 Smart Controllers Adapters Overview 17:00 Voltage Adapters Extensions 17:48 BOB2 Breakout Box 18:49 ISIO 200 (IEC 61850 I/O) 19:47 ARCO Control Workflow 21:04 ARCO Control Test Modules 22:39 Connectivity Options (USB / Ethernet / Wi-Fi) 23:14 ReCoPlan Test Plans 24:21 Distribution Automation Testing (RelaySimTest) 25:33 DER Protection Testing 26:18 Summary & Key Benefits #ARCO400 #RecloserTesting #Sectionalizer #DistributionAutomation #ProtectionTesting #OMICRON #PowerSystems
