Testing Binary Inputs, Binary Outputs and External Trip Input
Check that the connection from the output of the testing equipment to the device is correct and the binary
inputs, binary outputs and external trip input are connected correctly.
Testing Current Inputs
Using multi-phase test equipment, apply the corresponding test quantities and check the results.
Testing Protection Functions
The purpose of this test is to verify the correct setting of protection functions and the routing of signals. To do
this, you can feed the test signals with test equipment. Digital test equipment offers you multiple test
programs and test sequences.
Output Test
