Testing the voltage selection for 1 1/2 circuit breaker diameter
This test should verify that correct voltage is selected for the measurement in the energizing
function used for a diameter in a one and a half breaker arrangement. Apply single-phase volt-
ages to the inputs according to the tables below. "H" means a voltage of 100% U1b and "L"
means a voltage of 30% U1b. Verify that correct output signals are generated.
1.
Connect the signals below to binary inputs and binary outputs.
2.
Apply signals according to the tables and verify that correct output
signals are generated.
