Energy metering and efficiency analysis
The SimtoLink energy monitoring terminal reads three-phase and single-phase energy, power, power factor, and harmonics. It follows GB/T 17215 and IEC 62052, and it is used for energy metering and efficiency analysis in buildings, factories, and data centers. Protocols include Modbus and DL/T 645.
Accuracy is Class 0.5 or Class 1, which covers energy audits and carbon accounting. The SimtoLink energy monitoring setup is already in hundreds of office buildings, factories, data centers, and hospitals, and it supports finer energy management and retrofit work.
Parameters and what the terminal measures
SimtoLink energy monitoring terminals come in several builds, by phase count, connection method, and measurement depth, so the same family covers different metering jobs. The table is a typical reference:
| Type | Typical specification | Typical use |
|---|---|---|
| Three-phase | 3×220/380 V, 5 A–6000 A (with CT) | Factories, distribution rooms, main meters |
| Single-phase | 220 V, direct connection or with a CT | Lighting, outlets, sub-metering |
| Multi-circuit | 3–12 circuits per unit | HVAC, lighting, and power sub-metering |
| Power quality | Harmonics, voltage deviation, three-phase unbalance | Precision loads, data centers |
The terminal measures active and reactive energy, power, power factor, frequency, demand, and maximum demand. It analyzes harmonics from the 2nd through the 31st order. Communications are RS485, Modbus, and 4G, and energy-quality analysis software is included. Figures above are typical for standard models. The product specification governs.
Typical sites and what they delivered
From office-building sub-metering to data-center PUE analysis and hospital retrofits, the terminal covers finer energy control across several industries. Typical jobs and what they delivered:
Office-building sub-metering and retrofit
An office building installed 80 energy monitoring terminals and sub-metered HVAC, lighting, and outlets. After the high-use zones were identified and the retrofit was done, energy use fell by 22%.
Data-center PUE in finer detail
A data center meters each rack row and breaks PUE (Power Usage Effectiveness) down far enough to guide efficiency decisions.
Hospital metering and savings
A hospital meters energy by department and by equipment. That data supported a retrofit that cut annual energy use by 15%.
Workshop efficiency and demand control
A factory distribution room meters energy at workshop and production-line level, with demand alarms and over-demand control, so demand penalties are avoided.
Integration and the platform
- Platform: Connect to the SimtoLink energy management platform or a third-party BMS (Building Management System). A main-meter and sub-meter hierarchy is supported.
- Alarms: Set thresholds for over-demand and abnormal power. Act on an over-demand alarm quickly to avoid a penalty.
- Analysis: Export history and reports. A baseline makes the savings easier to see.
- Carbon accounting: Feed energy and carbon data into a carbon-accounting system for carbon-peak and carbon-neutrality reporting.
- Diagnosis: SimtoLink supplies the energy platform and a diagnosis service, and recommends retrofits from the monitored data.
How a project usually runs
A practical sequence for an energy monitoring project:
Export energy reports on a schedule and look for trends and anomalies. SimtoLink provides efficiency analysis, retrofit advice, and carbon accounting.
Support
SimtoLink helps select the terminal and supplies an energy management platform for sub-metering and efficiency analysis, plus diagnosis and retrofit advice. Manuals and quotations are available.
