Substation Automation
Substation Automation and Power Quality Analysis Unit
The SATEC ezPACTM SA300 series power intelligent device is an advanced power analysis and control equipment with high utility, ideal for utility and industrial environments. The ezPACTM SA300 series integrates multiple Intelligent Electronic Devices (IEDs) into a single powerful device. ezPACTM combines advanced control and automation functions, intelligent fault recorders, and power quality and event sequence recording features with automatic analysis and reporting. It also provides billing measurement, backup protection devices, and control devices, offering a complete solution for substation and industrial automation. ezPACTM is suitable for retrofitting as well as new utility projects.
For power substations using existing Electromechanical (EM) relays to achieve automation, this instrument is a highly cost-effective ideal choice. The ezPACTM series provides missing information for EM protection relays without interfering with the protection scheme, thereby extending the service life of these highly reliable devices by several years.
