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 rack
• Tariffs control system (fixed voltages, optical port reader, ripple control box)
• 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 and Functions

• 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)
  • Creep test (No-load test)
  • Starting current test
  • Dial test (Register test)
  • Meter constant test
  • Influence quantity test (voltage, frequency, harmonic distortion, etc.)
  • 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
• Measuring different constants of meters synchronously.
• With the protection function of overload, short voltage circuit and open current circuit.
