17.4 TESTING AND COMMISSIONING OF IEC 61850 IN
SUBSTATION
The benefits of using IEC 61850-compatible devices includes lower commis-
sioning costs, and decreased configuration and commissioning costs as the
devices do not need as much manual configuration as legacy devices can
require. Client applications no longer need to manually configure for each point
they need to access because they can retrieve the points list directly from the
device or import it via an SCL file. Many applications require nothing more
than setting up a network address in order to establish communications. Most
manual configuration is eliminated, drastically reducing errors and rework.

17.4.1 IEC-61850 Testing
Testing procedures include the following:

Functional element testing
Integration testing
Function testing
System testing
Tests also can be classified as follows:
Factory acceptance testing
Site acceptance testing
Complete system integration testing.
