DIGSI 4 Training

SIPROTEC 4 devices will parameterize and operate via DIGSI 4 software. SIPROTEC 4 is considered the standard for numerical protection systems in all fields of application. The SIPROTEC 4 device series implements the integration of protection, control, measuring, and automation functions optimally in one device.

The materials of the DIGSI 4 course are designed to help you be a professional in this field. Nothing beats hands-on learning from an engaging instructor who gives you the necessary information.

In the field of power system protection, new IEDs are available now with high capability and advanced functions. Working with such devices needs special training and most universities do not cover such topics.

But why Protection relay?

We provide online and pre-recorded videos in the field of power system protection and substation automation systems. So you can be updated in the field by our training packages wherever and whenever you are. You have lifetime access to files.
