Function	Integrated Energy‑measuring Meter	CM1 + Transformer + Multi‑function Meter
Accuracy	Voltage & current: Class 0.2; Active energy: Class 0.5	Voltage & current: Class 1; Measurement accuracy: Class 2 or none
Real‑time Monitoring Function	Built‑in sensors and monitoring modules for real‑time collection of electrical parameters including voltage, current, power, temperature and leakage current. Data can be transmitted to cloud or management platform via communication module for remote viewing and analysis.	No monitoring function. Protection actions are triggered only upon faults. Grid operating status data is not available.
Protection Function	Integrated protection functions including over‑current, short‑circuit, overload, over‑voltage, under‑voltage, over‑temperature and earth‑leakage. Flexible protection parameter configuration is mostly supported.	Generally only basic over‑current and short‑circuit protection. Limited protection scope with non‑adjustable parameters.
Remote Control & Management	Remote switch on/off, parameter configuration and event log query are available via RS‑485, 4G and other communication interfaces, which greatly improves O&M efficiency and flexibility.	Only local manual operation supported. No remote control function, resulting in low operation efficiency.
Event Log & Data Analysis	Event recording function stores historical data such as alarms and trips to facilitate fast fault location. It also provides energy statistics and trend analysis for energy‑efficiency optimization.	No fault or power‑consumption data recording. Manual troubleshooting is required after faults, which is time‑consuming and labor‑intensive.
