HY661 Six Phase Universal Relay Test Set

Engineered in strict accordance with the DL/T 624-2010 standard, our latest miniaturized relay protection tester incorporates extensive user feedback and a rigorous analysis of existing market solutions. By leveraging cutting-edge microelectronics, we have developed a high-performance, compact system that redefines field testing.

The device features an intuitive HMI (Human-Machine Interface) based on a familiar Windows operating environment, ensuring a seamless and efficient user experience. It is equipped with a high-performance embedded industrial computer and an 8.4-inch TFT true-color display (800×600), providing comprehensive visual data, real-time status updates, and integrated help documentation.

A standout feature is the intelligent software-based self-calibration. This eliminates the need for manual hardware adjustments or opening the chassis, significantly enhancing accuracy, stability, and long-term reliability.

1. Comprehensive Testing Versatility Capable of testing both traditional electromagnetic relays and modern microcomputer-based protection systems. It is specifically optimized for complex applications such as transformer differential protection and automatic busbar transfer (ATS) equipment.

2. Full Standard Compliance: Strictly engineered to meet and exceed the DL/T 624-2010 technical specifications (Technical Conditions for Microcomputer Relay Protection Test Equipment).

3. Intuitive HMI & Visual Telemetry Features a stable Windows-embedded operating environment with a user-friendly Human-Machine Interface (HMI). The 8.4-inch TFT true-color display (800×600) provides rich visual data, including real-time operational status and integrated interactive help documentation.

4. Industrial-Grade Control Interface Equipped with a robust, integrated metal industrial keyboard and a high-precision touchpad. This allows for full operational control in harsh field environments without the need for an external mouse.

5. Simplified PC Connectivity: Utilizes a standard USB interface for direct high-speed communication with a PC. No proprietary conversion cables or specialized adapters are required, ensuring "plug-and-play" simplicity.

6. High-Fidelity Linear Power Amplification The output stage features high-fidelity linear power amplifiers, ensuring exceptional precision for low-current signals while maintaining rock-solid stability during high-current injection.

7. Intelligent Self-Protection & Diagnostics incorporates advanced thermal management and a high-efficiency heat dissipation structure. Features include power soft-start, comprehensive fault self-diagnosis, and an automatic lockout/blocking function to prevent hardware damage.

8. Flexible Operation Modes: Supports standalone operation or control via an external laptop (optional). Both the host unit and external PC use the same software architecture, eliminating the learning curve for users switching between modes.

9. Dedicated DC Auxiliary Power Supply Includes an independent DC voltage source with dual outputs: 110V (1A) and 220V (0.6A). This provides reliable power for relays or protective devices requiring external DC excitation during testing.

10. Smart Digital Self-Calibration Integrated software-based self-calibration ensures long-term measurement stability. It eliminates the need for manual relay adjustments or opening the chassis, maintaining factory-grade accuracy in the field.

Q1: We are moving toward fiber-optic substations. Can I still use my traditional tester?

A: Only if it has Optical Digital Communication capabilities.
• Traditional: Uses copper wires to send analog 100V/5A signals.
• IEC 61850 (Digital): Replaces copper with fiber optics. The tester must output Sampled Values (SV) and receive GOOSE messages.
• Future-Proofing: Our high-end series acts as both an analog and digital tester. It can send virtual messages to a digital relay while simultaneously outputting analog signals, allowing you to bridge the gap during the industry's transition to smart grids.

Q2: I see testers with 3 current channels and others with 6. When is the 6-phase version mandatory?

A: It depends on the complexity of the protection logic you are testing.
• 3-Phase Testers: Ideal for standard overcurrent, distance, and directional relays. It covers about 80% of routine maintenance tasks.
• 6-Phase Testers: Essential for Transformer Differential Protection. To test differential relays effectively, you need to simulate currents on both the high-voltage and low-voltage sides simultaneously (3 phases each).
• The Recommendation: If your work involves power transformers, busbar protection, or complex automatic bus-transfer (ATS) schemes, a 6-phase tester is the industry gold standard.

Q3: Some testers are very light, but the more expensive ones are heavier. Is there a technical reason for this?

A: Yes, it is the difference between Linear and switching amplifiers.
• Switching Amplifiers: Light and portable, but they generate high-frequency switching noise, which can interfere with sensitive microcomputer relays.
• Linear Amplifiers (The Pro Choice): Though heavier, they provide "High Fidelity" output. They produce pure sinusoidal waves with nearly zero harmonic distortion.
• The Impact: In low-current testing (e.g., sensitive ground fault relays at 0.01A), linear amplifiers maintain incredible precision where switching types often fluctuate.
