Description
Product details
The CROXS CRA160Hi-A is an automatic, secondary injection relay test system designed for digital substations, generation plants, and high-voltage transmission networks. This portable 8 kg system provides a rugged, lightweight, and highly economical alternative to heavy imported testing kits from global legacy brands like the Omicron CMC 356, Doble F6150, or Megger SMRT series. The CRA160Hi-A is natively compliant with the IEC 61850 protocol and can seamlessly handle intelligent electronic device (IED) verification, high-speed GOOSE messaging schemes, MMS automation, and Sampled Values (SV). The standout hardware feature is its specialised 4×300V voltage configuration, which delivers an extended voltage reach and a high compliance testing ceiling. This makes it especially well-suited for testing overvoltage protection elements, undervoltage logic, and complex directional relay characteristics that need inputs well beyond the standard 130V injection limits. Driven by an AC-mains architecture (100–240V), it eliminates battery maintenance overheads for central/state utilities (GENCOs, TRANSCOs, DISCOMs), Independent Power Producers (IPPs), and renewable energy (solar/wind/hydro) contractors across India. Key Technical Specifications: Outputs: 6×20A / 3×40A current; 4×300V extended voltage channel range. Smart Grid Support: Full native compliance with the complete IEC 61850 protocol suite. Connectivity: 8 optical Ethernet ports (1-Gigabit fiber port) and 4 optical serial interfaces. Control UI: Standalone local control via integrated high-resolution 9-inch touchscreen. I/O Automation: 8 isolated binary inputs (20 kHz sampling) and 4 relay binary outputs. Synchronisation: Supports local hardware port interfacing, with GPS/Beidou synchronisation available as an optional feature. Product Applications & FAQ: Digital Substations: Automated fiber-optic testing of smart grid protective relays and Merging Units (MU). Extended Voltage Relays: Calibrating utility-grade overvoltage and directional protection elements up to 300V. Q: Why choose the 4x300V setup over standard 6x130V sets? A: It provides a much higher voltage ceiling per channel, essential for testing specific directional relays used by large utility grids, generation plants, and IPP switchyards. Q: Is external battery management required? A: No. The unit operates strictly on universal AC-mains power, providing continuous all-day field testing uptime.
