Product Introduction

Digital Energy Meter Calibration Platform Series Products Designed according to standards such as "GB/T 37006-2018 Digital Energy Meter Inspection Device", used for laboratory batch verification of digital energy meters compliant with IEC61850 standard, supporting virtual verification and virtual load verification methods.
 

Features

• Dual Verification Modes: Supports laboratory verification of digital energy meters using virtual load verification mode with real-time analog sampling or virtual verification mode with digital fitting.
• Comprehensive Test Items: Supports tests including basic energy error, energy meter pulse constant test, daily timing error test, voltage influence test, frequency influence test, harmonic influence test, phase sequence influence test, voltage asymmetry influence test, start-up test, creeping test, and more.
• Protocol Testing: Supports IEC61850-9-1, IEC61850-9-2, IEC61850-9-2LE protocols, with flexible configuration of communication parameters such as ASDU unit count, sampling points, SVID, APPID, MAC address, and channel number. Supports protocol tests for event recording, sampling value consistency, channel anomalies, sampling rate impact, and network anomalies of digital energy meters.
• IR46 Waveform Support: In virtual verification mode, supports output of various test waveforms including 5th harmonic, flat-top wave, sharp-top wave, interharmonic pulse train trigger wave, odd harmonics, and half sine wave.
• Event Simulation: Supports communication fault simulation tests such as frame loss, communication delay, and channel anomalies, comprehensively assessing the communication functions and fault tolerance of digital energy meters.
• Modular Design: Adopts modular design with 8 meter positions per rack, freely expandable to 8, 16, 24, 48 meter positions, etc.
• SCL File Parsing: Supports SCL configuration file parsing, directly configuring corresponding SVID, APPID, sampling points, ASDU count, channel configuration, and other information based on selected MU.
• Traceable Simulation System: Models with analog input modules can also use standard energy meters (such as COM3000) for accuracy verification and value transfer.
• Multi-gear Automatic: Analog sampling adopts multi-gear automatic switching and FIR filters to improve dynamic range and reduce signal-to-noise ratio. Uses 24-bit AD chip and 512x oversampling technology to greatly expand bandwidth and improve accuracy.
• Automatic Verification System: Equipped with automatic verification system, capable of fully automatic verification of all verification points of digital energy meters according to edited verification plans. Features report template editing and generation, supports data storage management, data viewing, and searching.
