Carrier-based Wireless Secondary Voltage Drop Load Tester
Product Introduction
The MOEORW-W8107 Carrier-based Wireless Secondary Voltage Drop Load Tester is the third-generation self-developed PT/CT transformer comprehensive testing equipment of our company. It strictly complies with the State Grid "On-site Operation Guidelines for Electricity Metering Devices", and is specially designed for on-site verification of power metering, PT/CT secondary circuit testing, wiring fault diagnosis and power quality analysis. Breaking the limitations of traditional wired testing equipment, it adopts exclusive secondary line carrier communication technology without temporary test cables, adapting to complex outdoor, urban and substation electromagnetic interference environments. The product supports bulk procurement for large clients, engineering supporting, dealer OEM customization, as well as single/small-batch procurement for small and medium enterprises and engineering teams. All orders follow unified factory quality inspection standards and complete technical after-sales services without downgrade, serving as a high-precision general-purpose device for power metering detection.

Lorem ipsum dolor sit amet consectetur adipisicing elit.
Kilometer-level Cable-free Carrier Communication, Anti-interference & Safer
Equipped with high-impedance carrier communication technology, the device supports three-mode synchronous sampling of carrier, wireless and cable with an effective communication distance of ≥1000m. It avoids the defects of traditional GPS wireless signals vulnerable to weather, building and electromagnetic interference. No temporary test cables are required, which will not affect grid metering accuracy and fundamentally eliminates short-circuit safety hazards caused by wiring. It simplifies on-site operation procedures and adapts to complex substation environments.
Intelligent Visual Touch Operation, Zero Threshold for Use
Adopting a 9-inch high-definition touch screen and Windows-like visual graphical interface, it supports handwriting and digital dual input with built-in intelligent operation guidance. All test data, vector waveforms and meter errors are displayed on one screen. It has passed 100,000 touch life tests for clear display in strong and weak light with extremely simple operation. It reduces operation and learning thresholds and supports standardized operation for all operators.
Full-scenario Wrong Wiring Identification, Multi-function & Cost-effective
Built-in professional wiring database accurately identifies 2256 types of 3-phase 3-wire and 18432 types of 3-phase 4-wire wrong wiring, supporting precise identification under ultra-low load (≤1mA). It automatically generates phasor diagrams and correction coefficients, realizes wrong wiring power calculation and wiring fault simulation training, and is compatible with all types of active/reactive, fundamental/harmonic meter verification. It integrates detection, calibration and training functions with strong universality.
High-precision Harmonic Analysis & Large-capacity Data Filing
Based on industrial hardware architecture of 32-bit CPU + high-speed DSP + FPGA, it supports full-dimensional accurate analysis of 1-51 harmonics, real-time monitoring of harmonic power, phase and flow direction. With dual storage backup, the built-in memory stores over 200,000 data records and U disk expands to 300,000+ records. Compatible with State Grid communication protocols, it supports one-click data export and docking with industry management systems, meeting standardized data filing and project acceptance specifications
Industrial Full-protection Design, Stable, Durable & Low Failure Rate
It supports AC30V-450V wide voltage input, built-in temperature and humidity sensor and multiple overvoltage/overcurrent protections, with optional large-capacity lithium battery. The whole machine passes 72-hour full-working-condition aging test, operating stably in all climates from -20℃ to +60℃, suitable for harsh working scenarios such as outdoor environments and substations. Its stability and durability exceed conventional industry standards.
