DIGSI 4 Training

SIPROTEC 4 devices can be parameterized and operated 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 material of the DIGSI 4 course is designed to help you to be a professional in this field. Nothing beats hands-on learning from an engaging instructor who gives you the information you need.

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 of the universities do not cover such topics.

But why us?

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.
