Product Overview

The MC-DLBX Power Waveform Recording and Analysis Instrument (hereinafter referred to as the MC-DLBX Analyzer) is a new-generation, high-performance waveform recording and analysis instrument developed by Hubei MECI Electric Power Equipment Co., Ltd. in response to market demand. This instrument integrates a waveform recorder, oscilloscope, multimeter, and power quality analysis function into one, featuring a portable design for convenient use.

The MC-DLBX analyzer’s hardware system employs state-of-the-art embedded technology and utilizes a 32-bit high-precision floating-point DSP for sampling. The 32-bit floating-point DSP boasts powerful data-processing capabilities and high processing speed, thereby ensuring both the sampling accuracy and sampling rate of the instrument. Moreover, the data-acquisition hardware features ultra-low power consumption, which underpins the instrument’s long-term reliable operation.

The MC-DLBX analyzer software system is composed of multiple operating systems. Under Linux, it implements data management, low-level device drivers, and external communication functions, while Windows handles the human–machine interface and data backup. The primary advantage of this architecture is its high level of data security and reliability, protection against malicious attacks, and a user-friendly human–machine interface, thereby achieving a high degree of integration between ease of use and equipment reliability.

The device fully complies with and exceeds the industry standards issued by the State Power Ministry, namely “Technical Standard for Dynamic Fault Recording in 220–500 kV Power Systems” (DL/T 553-94) and “Inspection and Testing Requirements for Dynamic Fault Recording Devices in 220–500 kV Power Systems” (DL/T 663-1999).

Product Features

  • Building on the strengths of the company’s previous two generations of waveform analyzers, the MC-DLBX analyzer further enhances performance. Its key features are as follows:

This device can operate continuously on the line for extended periods and fully implements all waveform recorder functions.
  • Multimeter functions: This high-precision, intelligent meter can measure voltage, current, high frequency, and digital signals; calculate RMS value, harmonics, phase angle, power, frequency, positive- and negative-sequence components, and generate waveform diagrams—offering far more advanced capabilities than a conventional multimeter.
  • New equipment commissioning function: establishes a closed-loop circuit with the protection tester to verify the performance of the new equipment.
  • Intelligent self-diagnosis function: continuously performs self-tests on the device’s hardware; triggers alarms upon detection of hardware faults; and provides password protection and log recording for convenient maintenance.
  • High-capacity configuration: The device offers large capacity and flexible configuration, supporting up to 16 analog channels and 12 digital input/output channels.

  • Adjustable data recording length: The waveform recording format complies with the requirements of DL/T 553-94 and DL/T 663-1999, and the recording lengths for segments A, B, C, and D can be manually set.
  • Supports multiple start-up modes: mutation, limit violation, frequency mutation, frequency limit violation, positive/negative sequence, oscillation, digital input, harmonic limit violation, remote start, and manual start, among others.
  • Comprehensive analytical capabilities: The system can perform phasor, harmonic, sequence component, frequency, power, symmetrical component, and impedance analysis, and can record daily data variations to enable trend analysis.
  • Data format conversion functionality: waveform recording data can be converted to standard COMTRADE and MOLI COMTRADE formats for use in other power analysis software; trend data can be exported in Excel format for convenient custom statistical analysis by users.
  • Multi-system technology: By leveraging multiple systems and employing multi-threading, this approach ensures real-time performance for concurrent communication, analysis, and monitoring tasks, thereby achieving a high degree of integration between user convenience and device reliability.
  • Multiple networking options: Equipped with Ethernet and serial ports to meet networking requirements across various media and protocols.
  • Multiple output modes: All computed results and data can be conveniently displayed, printed, and stored on the local backend workstation, or remotely transmitted via the system communication network, program-controlled switching network, or local area network to the dispatch center for monitoring, storage, retrieval, and analysis.
  • Supports GPS time synchronization: Offers multiple GPS time-sync methods to ensure the accuracy of the device clock.
