Product Overview

The MCG-300S digital multimeter is a dedicated testing tool launched by Hubei MECI Electric Power Equipment Co., Ltd. for the network communication process of digital/intelligent substations. It automatically detects and parses process-level communication message information, presenting it to users in an intuitive manner through various methods such as RMS value, phase, waveform, and switch status, while also performing classified statistics on messages. In addition, it supports message-sending tests and provides multiple protection verification modules, making it an essential tool for the installation, commissioning, operation, and maintenance of digital/intelligent substations.

Product Features

  1. Features a 5.7-inch true-color LCD display with a resolution of 640×480 pixels, supporting both touchscreen and keyboard control modes.
  2. Features two pairs of optical Ethernet ports, two pairs of optical serial ports, and one IRIG-B synchronization port.
  3. It can simulate the output of IEC 61850-9-1/2 optical digital messages from a merging unit (MU) to test optical digital relay protection devices.
  4. Supports the import of SCL files (such as SCD, ICD, and CID) to extract the required device instance configuration information and complete test configuration.
  5. Supports network packet sniffing and automatically matches packets against SCL files, flagging any mismatches.
  6. Supports voltage and current output testing; six voltage channels and six current channels can be mapped to multiple sampling-value control block outputs.
  7. Supports state-sequence output testing and features short-circuit fault calculation.
  8. Supports GPS-triggered output of sampled values, enabling multi-unit synchronous output testing.
  9. The optical serial IEC 60044-8 message transmission rate is selectable between 2.0 Mbps and 10.0 Mbps.
  10. Supports SV message output time uniformity and rated delay monitoring;
  11. Supports optical port traffic monitoring;
  12. Supports GOOSE transmission mechanism monitoring;
  13. It features polarity verification and phase-checking functions for optical digital SV control blocks.
  14. It features optical-port data forwarding and can be used for serial packet inspection;
  15. Supports single-fiber network connection (no Link mode);
  16. Supports monitoring of SV, GOOSE, and IEEE 1588 messages, and provides multiple data visualization modes, including waveforms, amplitudes, phases, frequencies, harmonics, dispersion metrics, abnormal message detection, and event sequence recording.
  17. Supports SV message resampling;
  18. Powered by a built-in 11,000 mAh rechargeable lithium battery, with a continuous operating time of ≥6 hours.

 

Professional Version:

  1. Supports VLAN testing for switches;
  2. Supports MMS message sending and receiving testing;
  3. Supports PCAP data playback testing;
  4. Supports SOE response time testing for smart terminals;
  5. Supports network stress output testing;
  6. Supports simulated output testing of abnormal messages;
  7. Supports a variety of protection verification and testing functions, including setpoint verification, differential testing, harmonic output testing, and more.
  8. Supports network packet capture and analysis testing.
