Product Introduction

◉ Suitable for conducting calibration work on three-phase standard energy meters or standard power sources that meet R46 instructions at 0.01 level and below.
The accuracy of the three-phase power source itself reaches level 0.02. When it is disconnected from the standard meter (sent for inspection), it can also be used to calibrate three-phase standard energy meters that meet R46 instructions at level 0.05 or below.
Suitable for establishing high-level single/three-phase power energy measurement standards in various fields such as metrology, electricity, military industry, manufacturing, and scientific research.
Reference standards: GB/T 17215.701-2011 "Standard Electric Energy Meter", JJG 1085-2013 "Verification Regulations for Standard Electric Energy Meters", etc.

Functional Features

Maximum output/measurement: Voltage up to 576 V (customized for a wider range of voltages), current up to 120 A, ensuring stable output under full load conditions.
Minimum output/measurement: The current output and measurement have a minimum limit of 0.25 mA, which is the basis for the starting test of the tested standard energy meter.
◉ Fundamental frequency range: 45 Hz to 400 Hz (output), 45 Hz to 1 kHz (standard meter), both output and measurement bandwidths are better than the bandwidth of the fundamental and third harmonics of the electric current.
Harmonic output/measurement: Both hold the 2nd to 127th harmonics, suitable for verifying standard harmonic energy meters or analyzing the harmonic content and total harmonic distortion of the source being tested.
Complex waveform test: Built in commonly used waveforms such as high-frequency waves, peak waves, subharmonics, and odd harmonics, as well as other complex waveforms defined by oneself for impact testing.
Half wave rectification test: equipped with TD3410 half wave rectification waveform test box to complete DC/even harmonic (half wave) test.
Other testing functions: oscilloscope, phasor graph display, harmonic bar chart, power stability testing, trend change curve, data statistical analysis, etc.
◉ Mobile measurement and control platform: It can observe or control the output of measurement values through its LCD touch screen, and can be used manually to check the meter or source.
◉ Specialized verification software: Full automatic or full automatic calibration of the verified table, data recording, analysis, management, and certificate export.
◉ Multi meter calibration table: Three meter positions can be selected, and the table is equipped with interfaces for power output, light/electric pulse, communication, etc. It can calibrate three standard energy meters at the same time.
◉ Specialized verification software: The table library has strong functions and supports communication with the vast majority of verified standard tables/sources, enabling full or semi automatic verification.
◉ It has complete data management functions, including printing and sealing of certificates, retrieval of historical certificates, storage of historical data, and analysis of holding year errors.
The software also supports error correction configuration, device stability testing, uncertainty analysis, etc. for high-level three-phase standard meters, regularly verifies device accuracy, and records error comparison curves.
