Our smart meter applications include:
- Manufacturing plants, processing workshops, and heavy industrial bases. These customers use three-phase 400V or higher voltage systems and require accurate monitoring of energy consumption, load, power factor, and peak electricity consumption.
- Commercial and building facilities/multi-tenant buildings. Commercial buildings such as office buildings, shopping malls, hotels, data centers, and retail chains have three-phase loads, complex equipment, and high electricity consumption.
- Multi-tenant buildings may also use three-phase meters for sub-metering to allocate electricity costs among tenants and manage electricity usage.
- In the EU, green building standards and energy monitoring are implemented.
- Power distribution companies, electricity service providers, and smart grid projects also purchase three-phase meters in large quantities for use in substations, distribution networks, substations, and public infrastructure.
