On-site energy monitoring system Sfere3000 applies at the small industrial and commercial projects


Why need the small local EMS system?

Since the wireless data transmission technology has fast growing in recent years which makes the possibility of the cheap and reliable data transmission provide by the web serve operator comes true. In this regard, many of the Cloud base power management software or energy management software were launched in the power distribution industry. With comprehensive software design and mature communication and data acquisition devices deployment, Cloud based PMS can dramatically improve the management efficiency and reduce  human operation and maintenance costs in a long term prospect for those multi project management activities. Meanwhile, a large number of small and medium-sized enterprises and business entities may not have as much multi project management demand, and those enterprises may not be able to afford the cost of devices deployment and server installation. For those projects scale is small with less monitoring devices, and short distances, what other options can they have besides cloud based power monitoring systems? Is it possible to have an on-site rather than Cloud based power monitoring system that can be developed based on the existed software, communication, and other technologies to improve the safety, reliability, and stability of power transformation and distribution system operation. Is there a management software can meet the all-need monitoring of the environment of 35kV and below voltage level power transformation and distribution systems, accelerated the digitalize and information internal sharing of the energy consuming enterprises, reduce operating manpower costs, improve production efficiency, speed up the response to abnormalities in the process of power transformation and distribution, and enhance the power supply and distribution service guarantee capability? Sfere Electric heard the voice from the market and its R&D team has brought SFERE3000 power monitoring software, providing a cost-effective small power monitoring and operation system for the industry.
