Three-Phase Meter Test Equipment for Smart Meters

The YC-1893D Series Three-Phase Energy Meter Test Equipment is widely used by power utilities, energy meter manufacturers, metrology and quality inspection institutions, as well as industrial and mining enterprises. It is designed for the calibration and verification of three-phase three-wire or three-phase four-wire multifunction energy meters, including electronic energy meters, mechanical energy meters, electromechanical energy meters, and three-phase multi-user meters.

Features and Functions

1. Active and reactive energy and power metering tests
2. Automatic calibration for starting current and no-load creep tests
3. 24-hour drift, measurement error, and deviation analysis
4. Voltage, frequency, harmonic distortion from 2nd to 21st order, and phase sequence influence testing
5. Non-disconnection testing with open-circuit and short-circuit protection
6. Simultaneous multi-channel current measurement with auto-detection optical scanning head
7. Manual and electric meter testing modes with PC-based test software and barcode data input
8. Scalable meter rack with 3 to 60 test positions for batch testing
9. Bidirectional energy error testing for both active and reactive energy
