Advanced Portable Power Analysis: The ZXBX-12 Recorder

In the field of electrical power system testing and maintenance, portable recording analyzers are essential for capturing transient events, validating protection systems, and performing generator acceptance tests. Among the available options, the ZXBX-12 Portable Electricity Recording Analyzer stands out due to its integrated testing templates, flexible analysis features, and robust technical design—making it a valuable tool for technicians and engineers.

Unlike conventional power quality analyzers or basic oscilloscopes, the ZXBX-12 is specifically designed for comprehensive electrical testing, including generator commissioning, protection tests, and harmonic analysis. Its combination of hardware capability and dedicated software templates offers a level of integration not always present in generic field recorders.

Key Features and Capabilities

The ZXBX-12 is preloaded with test templates for common power system applications, allowing users to perform tests such as:

1.Generator short-circuit and no-load characteristic tests

2.Excitation system disturbance and 10% step tests

3.De-excitation constant measurement

4.Load rejection tests

5.Synchronization device verification

The software supports real-time graphing with zoom and positioning tools, spectral analysis up to the 1024th harmonic, phasor diagram plotting, and symmetrical component analysis. It also includes mathematical tools for combining signals (addition, subtraction, multiplication, division, integration), simplifying derived quantity calculations. A significant productivity feature is its ability to automatically generate Word and Excel test reports with annotated curves.

Technical Performance

The instrument offers 12 analog input channels with selectable ranges:

1.Voltage: ±10V, ±200V, ±400V

2.Current: ±20mA

3.One additional channel supports ±100mV inputs (suitable for shunts or specific sensors).

Accuracy is well-specified for field measurements:

1.±0.5V on the ±400V range

2.±0.2V on the ±200V range

3.±0.01V on the ±10V range

4.±0.02mA on the 20mA range

5.±0.2mV on the 100mV range

It also includes 12 digital inputs for status or event recording (compatible with 12–220VDC) and three relay outputs (rated 220VAC/1A) for controlling external devices or triggering tests.

Comparison with Conventional Equipment

Many portable power analyzers focus primarily on power quality (e.g., harmonics, flicker, sags/swells). The ZXBX-12 includes these functions but extends further into generation and protection testing. In contrast, typical power analyzers lack built-in templates for generator no-load/short-circuit tests or automatic report generation with curve annotations.

Compared to using separate devices—an oscilloscope for transients, a power meter for energy, and a data logger for trends—the ZXBX-12 integrates these into one system. Its 12.1-inch touchscreen, onboard 8GB storage, and USB ports improve usability in field environments. The split-chassis design offers operational flexibility, allowing the user interface to be positioned independently from signal connections.

Conclusion：

The ZXBX-12 Portable Electricity Recording Analyzer is a versatile and capable instrument tailored for electrical testing applications, especially in generation and protection. Its combination of accurate signal acquisition, dedicated analysis functions, and automated reporting makes it a superior choice for technicians and engineers who require depth and efficiency in field measurements. For utility, industrial, or commissioning engineers, this device represents a significant step up from general-purpose power analyzers.
