ZXBLQ-3A: Revolutionizing Three-Phase ZnO Arrester Testingwith WirelessPrecision
Introduction
Zinc Oxide (ZnO) surge arresters are critical guardians of electrical infrastructure, absorbing dangerous overvoltages. Ensuring their health requires precise measurement of leakage current parameters – key indicators of insulation moisture, valve aging, and imminent failure risks. The ZXBLQ-3A Three-Phase Zinc Oxide Arrester Tester emerges as a next-generation solution, combining comprehensive electrical measurement, unprecedented wireless freedom, and rugged portability to outperform conventional testers.
Beyond Conventional Limitations: Key Advantages
Traditional arrester testers often involve cumbersome cabling, limited phase measurement, and restricted operating environments. The ZXBLQ-3A addresses these challenges head-on:
True Three-Phase Synchronized Measurement: Simultaneously measures current and voltage on all three phases, providing a complete system view crucial for accurate diagnostics under actual operating conditions (energized test) or controlled settings (de-energized/lab test). Current and voltage sensors are fully isolated, ensuring safety and reliability.
Long-Range Wireless Freedom (Up to 2000m): Eliminates the hazards and logistical nightmares of long cable runs. Its wireless PT signal transmission (>400m standard, extendable to 2000m) allows safe reference voltage acquisition from distant sources, significantly enhancing flexibility during live-line testing in substations or along transmission lines.
Unmatched Versatility: Seamlessly handles de-energized (offline), energized (online), and laboratory testing scenarios with a single instrument.
Enhanced Safety & Portability: Powered by a high-energy internal lithium battery (operating voltage <12V) or an external adapter. This intrinsic safety, coupled with weak internal currents, minimizes risks. Its compact, lightweight design (Host: 36x26x14cm, 5kg; Accessories: 42x33x20cm, 9kg) and rugged, dust-proof, waterproof, anti-corrosion enclosure make it ideal for demanding field use.
Advanced Signal Acquisition & Flexibility: Offers dual voltage reference methods:
Synchronization via cable (40m, extendable).
Long-range wireless synchronization (>400m, extendable).
Supports "No Voltage" mode using software calculation for reference (where permitted by standards).
High-Fidelity Data & Comprehensive Parameters: Boasts a high sampling rate and advanced digital signal processing for exceptional accuracy (±2% reading ±1 digit for current >100µA and voltage >30V; ±5% ±1 digit wireless) and strong anti-interference. Measures critical parameters including:
Total Leakage Current Waveform (Peak, Fundamental RMS)
Resistive Leakage Current (Fundamental RMS, 3rd/5th/7th Harmonic RMS, Peak Values Ir+/Ir-)
Capacitive Leakage Current (Fundamental RMS)
Voltage/Current Phase Angle Difference
PT Voltage RMS
Arrester Power Loss
Robust Data Management & Reporting: Features a large 800x480 color LCD touchscreen, high-speed thermal printer, USB interface, and a massive 4G SD card for extensive data storage. The industrial-grade OS enables direct shutdown and powerful functions: historical data management, in-depth analysis, and automated report generation/printing.
