Intelligent energy monitoring
Digital protective relay
Mitsubishi Electric is expanding its highly configurable and scalable "MEnergy solution" for system protection and monitoring to include a protective relay and a soft starter.
In addition to the MEnergy monitoring concept for the transparent recording and analysis of energy data in real time, Mitsubishi Electric is now offering the flexible and modular MEprotect digital protection system for the first time on the European market. A unique feature of the digital protection relay is that it can be used in both low-voltage and medium-voltage projects.
The highly configurable device provides information on power quality, load profile and power requirements and therefore valuable input for predictive maintenance. The intuitive user interface is used to set up the conditions under which a warning message is to be issued or, if necessary, an emergency shutdown is to be carried out.
"The MEprotect models are a key component of our monitoring solutions and are extremely versatile, from simple motor protection to complex solutions for generator and transformer protection," says Michael Finke, Product Manager Low Voltage Switchgear at Mitsubishi Electric. A standardized hardware and software platform guarantees easy expandability, while the connection to higher-level automation systems and the monitored plant components is easily implemented using fieldbus technology.
Another new component of the Energy System is MEsoftstart. This is a series of digital soft starters that ensure gentle motor starting, particularly in harsh ambient conditions, and thus contribute to electrical and mechanical system protection.
The energy concept is rounded off by monitoring kits based on the EMU4-FD1-MB measuring module in three expansion stages - basic, easy and smart. This records electrical characteristics such as voltage, current and harmonics for efficient energy management and cost savings. pb
