10.2 Indications on operation
• The SACE PR010/T unit can be used with all PR112/P-A and PR112/ PD-A protection
releases.
• The SACE PR112/PD-A releases must be connected to the auxiliary power supply for use
with the SACE PR010/T unit.
NOTE: The PR112/P-A software release can be read on the display by choosing
in sequence in READ mode, starting from the main menu:
- Config./Program
- Information
WARNING
Connect the test wire provided (between the SACE PR010/T and the SACE
PR112) the right way round (see the adhesive labels on the connectors).
Manual test example for release PR112/P-A.
NOTE: the data indicating the type of CB and protection, the rated current of the
CTs and the Neutral setting are automatically identified by the PR010/T test unit.
In this example, protection function "S" is tested with curve t=k, threshold I2=1.20*In, curve
t2=0.4 s supplying a fault current equivalent to 2 times the rated current (In).
1. From the main menu select 1 (Operation mode)
2. Select the PR112-A unit with x (PR112-A)
3. Select the type of activity with 1 (Test)
4. Select the type of test with 1 (Protections)
5. Select the test mode with 2 (Manual)
6. Select the type of setting used to test the protections with 2 (User setting)
7. Select the protection function you want to test with 2 (S protection test)
8. Using the arrow keys, fill in the page displayed as
follows:
9. Select the phase (or phases) on which to simulate the fault current (L1+L2+L3)
10.Press ENTER to activate fault simulation.
S-PROT: t=k, ON
S protection test: t=k
L2: 1.2In => 2400 A
T2: 0.4 s
I-f: 2.00 => 4000 A(*)
(*) In this example, the
automatically identified
rating of the current
sensor is 2000 A. Check
that I-F is lower than I3.
