Commissioning manual
Testing functionality by secondary injection
that this reading corresponds to the injected impedance. No start or trip signals
shall be activated.
3.
Feed the IED with current and voltage corresponding to the apparent impedance:
Test #3, as shown in figure 39. Read the analog outputs for R and X and check
that this reading corresponds to the injected impedance. The signals START and
STZ2 shall be activated instantaneously and the signals TRIP and TRZ2 shall be
activated after the set delay tZ2.
4.
Switch the current infeed injection off. The function shall reset. Turn the current
on with the values corresponding to Test #3 and measure the time to activation
of signal TRZ2. This time shall be compared to tZ2.
5.
Feed the IED with current and voltage corresponding to the apparent impedance:
Test #4, as shown in figure 39. Read the analog outputs for R and X and check
that this reading corresponds to the injected impedance. The signals START,
STZ2 and STZ1 shall be activated instantaneously and the signals TRIP, TRZ2
and TRZ1 shall be activated after the different set time delays.
6.
Switch the current infeed injection off. The function shall reset. Turn the current
on with the values corresponding to Test #4 and measure the time to activation
of signal TRZ1. This time shall be compared to tZ1.
