CRA160LHi-A Three Phase Automatic Relay Test Set (AC-Mains, Extended 4x300V Voltage) The CRA160LHi-A Protection Relay Test Set is a premium, automated secondary injection system designed for traditional and numerical substation panels, power generation plants, and heavy transmission networks. Designed as a rugged, lightweight alternative to heavy imported test kits like the Omicron CMC 356 or CMC 500, the CRA160LHi-A focuses on pure, high-precision analog injection. By omitting complex digital IEC 61850 software stacks, it delivers maximum cost-efficiency and operational reliability for field commissioning teams across India. The standout feature of this model is its specialised 4×300V voltage channel configuration, which provides a significantly extended voltage reach and a high compliance testing ceiling. This makes it uniquely suited to evaluate overvoltage protection elements, undervoltage logic, and complex directional relay characteristics that require testing inputs well beyond the standard 130V injection limits. Driven entirely by a universal 100–240V AC-mains architecture, this highly portable 8 kg system eliminates battery maintenance, charging cycles, and transit restrictions for engineering teams. Key Technical Specifications: Current Outputs: 6×20A / 3×40 A high current capability for secondary injection. Voltage Outputs: 4×300V extended voltage channel range for utility-grade relays. Output Power: Delivers 140W at 20A / 220W at 40A (current) and 90W at 300V (voltage). Power Architecture: Universal AC-mains operation (100–240V) with no battery dependencies. Binary Handling: 8 fully isolated binary inputs (20 kHz sampling accuracy) and 4 relay binary outputs. Local Control Display: Integrated high-resolution 9-inch touchscreen interface. Hardware Portability: Ultra-lightweight 8 kg rugged field enclosure. Compliance Certification: CE, EAC, and ISO-approved manufacturing standards. Primary Applications: Extended Voltage Relay Testing: Precise calibration of overvoltage, undervoltage, and directional protection elements up to 300V. Substation Grid Maintenance: Routine secondary injection testing for central and state utilities (GENCOs, TRANSCOs, DISCOMs), Independent Power Producers (IPPs), and independent transmission lines. Fixed T&C Laboratories: Dedicated calibration bench hardware for EPC contractors and industrial testing laboratories where stable AC mains is available. Frequently Asked Questions (FAQ) for Engineering Teams: Q: Does the CRA160LHi-A support digital substation IEC 61850 protocol networks? A: No. The L-Series models are focused purely on robust analog injection for static and numerical relays. By removing IEC 61850 software blocks and fiber-optic ports, it serves as a highly economical option for projects that do not require digital smart grid mapping. Q: What are the main benefits of the 4x300V setup over standard 6x130V kits? A: The 4×300V setup provides a much higher voltage ceiling per channel. This configuration is essential for testing specific directional relays and overvoltage protection schemes that are commonly used by large utility grids and IPP switchyards.
