Extreme Performance Stability Three-Phase Stationary Meter Test Bench to Calibrate Smart Meter

Stationary Three Phase Meter Test Bench

The YC1893D meter test system is a full-automatic test system for testing and calibration of both single-phase and three-phase electric energy meters, which composes of:

• Three-phase Power source

• Three-phase Reference standard meter

• Meter suspension test racks for testing of both 1-phase/3-phase meters

• Smart meter function test system (fixed voltages, optical probe, relay control test and ripple control box as option)

• Other necessary parts

• PC and software controlling the whole system

The YC1893D meter test system is fully compliant with the IEC 60736 standard and is suitable for testing meters according to the following standards:

• IEC 62052-11 and IEC 62053-11, -21, -22, -23, -24

• IEC 62056

• EN 50470-1, EN 50470-2, EN-50470-3

• IEC 61010

Features

• The meter test system can measure mechanical meters, electronic mechanical meters and electronic meter by the way of automatic, semi-automatic or manual operation.

• Aluminium alloy material, light and strong and corrosion resistant.

• Automatic positioning rotor mark of disc of mechanical meter, with more efficiency.

• The swing together of the scanning heads simplifies the control.

• Fully automatic completion of the following tests:

  • Accuracy test in all four quadrants (active, reactive and apparent energy)

  • Repeatability of error test

  • Creep test (No-load test)

  • Starting current test

  • Dial test (Register test)

  • Meter constant test

  • Influence quantity test (voltage, voltage unbalance, frequency, harmonic distortion, reverse phase sequence.)

  • Calibration of reference standard meter having lower accuracy than the employed reference standard

  • Pre-warming

  • Dips and Interruptions

  • Testing single-phase meters under tampered conditions

  • Sub Harmonics as per IEC standards

  • Odd Harmonics as per IEC standards

  
  

• Measuring different constants of meters synchronously.

• With the protection function of overload, short voltage circuit and open current circuit.
