YC-1893D series three‑phase energy meter calibration system with ICTs is designed for high‑efficiency, high‑precision verification of three‑phase three‑wire / four‑wire multi‑function, electronic, mechanical, and electromechanical meters. It supports 24 meter positions and integrates full‑featured testing with intelligent management.
Core advantages:
Full electrical parameter verification: active/reactive power & energy, starting, creeping, error analysis, and influence tests (voltage, frequency, 2–21st harmonics, phase sequence)
Advanced special functions: four‑quadrant reactive testing, prepaid meter verification, daily time error calibration, communication test & broadcast timing
High stability output: voltage 40–450 V, current 1 mA–120 A (up to 230 A optional), distortion ≤0.3%, stability 0.02%/120s
Smart operation: auto/manual modes, barcode input, PC‑based data processing, report printing, and current open / voltage short protection
Widely used in power utilities, meter manufacturers, metrology centers, and industrial enterprises.
