II.Functions:


• AC current and voltage based protection relay unit test

• DC current and voltage based protection relay unit test

• Frequency protection relay unit test

• Harmonic protection relay unit test

• Differential protection relay unit test

• Zero-sequence protection relay unit test

• Distance protection relay unit test

• Power system network fault simulation
