Description

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.

Protection Relay Test System

Myriad Industrial Solutions LLP offers professional-grade protection relay test systems engineered for electrical substation commissioning, industrial maintenance, and relay testing across India. As an authorized direct distributor, we provide high-tech alternatives to expensive legacy international platforms, delivering localized support, calibration compliance, and domestic procurement advantages. Our product lineup is split into two specialized engineering categories to match your technical requirements: the high-power TESIENT MP3000 Series and the ultra-high accuracy CROXS Platform. 1. TESIENT MP3000 Series (Models: MP3000A, MP3000F, MP3000A1) The TESIENT series serves as a high-power workhorse testing system designed to deliver high Volt-Ampere (VA) output capacity. This makes it suitable for testing legacy, high-burden electromechanical relays, directional overcurrent, distance, and heavy-duty current injection schemes where raw power delivery is required. - Hardware Features: Standard configurations provide up to 6 independent current sources (maximum 30A per channel) and 4 independent voltage sources (maximum 300V per channel). - Amplifier Design: Built using high-fidelity linear amplifiers to isolate testing channels and completely bypass standard harmonic noise injection. - Transient Simulation: Capable of generating transient fault signals up to 5 kHz for dynamic protective testing. - Digital Integration: Built-in capabilities support automated protection relay testing architectures and native IEC 61850 substation testing functions. 2. CROXS Advanced Testing Platform The CROXS platform is engineered as an ultra-high-precision asset for modern numerical testing environments. While it features a lower VA power capacity compared to the TESIENT series, it delivers superior measurement and injection accuracy. - Application: Optimized for testing highly sensitive numerical relays, multi-function microprocessor protection schemes, precision metering verification, and advanced digital substations. - Digital Substation Excellence: Native handling of IEC 61850 GOOSE messaging, Sampled Values (SV), and process/station bus validation parameters. - Accuracy Tier: High-precision signal generation ensures exact validation of trip curves and fine-grained protection thresholds without distortion. Software Workflow and XRIO Compatibility: Both the TESIENT and CROXS platforms natively support direct XRIO file imports. In the global protective relay testing market, raw XRIO files act as structured parameter text documents containing specific relay setting points. Note that no software on the market maps a raw XRIO file into a graphical trip curve automatically without an underlying model template. Our systems execute this industrial workflow smoothly. By utilizing pre-configured relay model templates matching major international manufacturers, engineers can import a standard XRIO file to automatically populate all settings, parameters, and fields. The underlying software then reads these data points to plot coordinates, map multi-section coordinated curves, and reconstruct exact multi-phase relay characteristics (such as overcurrent, differential, or Z-plane impedance trajectories). Commercial and Procurement Advantages for Indian Industries: Purchasing high-ticket test sets through third-party directory aggregators often clusters advanced technology with basic manual injection boxes. Buying directly from Myriad Industrial Solutions LLP ensures direct technical alignment with your project specification criteria. - Complete regulatory transparency as an official importer and distributor. - Localized physical calibration services matching national compliance metrics. - Direct GST-compliant commercial invoicing. - Accessible on-site technical field support and rapid domestic shipping across industrial zones. For formal technical documentation, catalog files, compliance certifications, or to request an official commercial quote (RFQ) tailored to your testing criteria, contact Myriad Industrial Solutions LLP directly through our verified channels.
