The importance of ZX-1600 microcomputer relay protection tester
The ZX-1600 Microcomputer-Based Relay Protection Test System is a state-of-the-art device designed to meet comprehensive testing requirements for both traditional relays and modern microprocessor-based protection systems. With its advanced features and high precision, it stands out as a versatile tool for power system professionals. This article explores its technical capabilities and compares it with conventional test systems.
Key Features and Advantages
Multi-Channel Output The ZX-1600 offers six-phase voltage and six-phase current outputs, enabling simultaneous testing of complex protection schemes like transformer differential protection and auto-reclosing devices. In contrast, older test systems often lack sufficient channels, requiring multiple devices or sequential testing.
High Precision and Waveform Quality Equipped with a DSP+FPGA architecture and 16-bit DAC, the ZX-1600 generates 2,000-point sinusoidal waveforms per cycle, ensuring superior accuracy (±0.2% for current/voltage). Traditional testers with lower DAC resolution (e.g., 12-bit) struggle to match this fidelity, especially for harmonic testing (2nd–20th harmonics).
User-Friendly Interface The Windows XP embedded OS with a 10.4-inch TFT display provides an intuitive workflow, while legacy devices often rely on proprietary software or limited interfaces. The inclusion of USB/network connectivity simplifies data transfer and GPS-synchronized testing—a rare feature in older models.
Robust Power Output
Current Source: 6×40A (240A parallel, 10s pulse) vs. typical 3×30A systems.
Voltage Source: 0–120V/phase (75VA) and ±160V DC, outperforming lower-capacity competitors. The high-fidelity linear amplifier ensures stability across small-current (5mA resolution) and high-current (240A) ranges.
Integrated DC Auxiliary Supply Built-in 110V/220V DC outputs eliminate the need for external power sources during relay testing—a convenience absent in many conventional testers.
Technical Comparison
Parameter | ZX-1600 | Conventional Testers |
Output Channels | 6-phase voltage/current | Typically 3–4 phases |
Current Accuracy | ±0.2% (±5mA) | ±0.5% (±10mA) |
Waveform Density | 2,000 points/cycle | ≤1,024 points/cycle |
Harmonic Generation | 2–20 orders | Often limited to 10–15 orders |
GPS Synchronization | Supported (optional) | Rarely available |
DC Auxiliary Output | 110V/1A, 220V/0.6A | Not integrated |
Applications
The ZX-1600 excels in:
Differential Protection Testing: Simulates unbalanced currents with precision.
Automated Relay Calibration: Self-calibration software avoids manual potentiometer adjustments.
Time-Critical Tests: 1ms–9,999s timing accuracy for fault scenarios.
The ZX-1600 sets a new benchmark for relay testing, combining high accuracy, multi-functionality, and user-centric design. Its advantages over conventional systems—especially in channel capacity, waveform quality, and integrated features—make it indispensable for modern power grid maintenance.
