CURRENT S ENSORS

 

PRIM AR Y TESTING

1VLG5000 17 C

 

Step 6/7

 

Check current metering for the phase and measured current in other phases on the protec-
tion relay LHMI Measurements view.

 

Current must be zero in phases which are not under the primary injection test.

 

 

Figure 40: Measurements view

 

“Io-A” in Measurements view is a measured value, not a calculated one.

 

 

Step 7/7

 

After testing of all 3 phases, install the back-overpressure relief flap. Set up the Ith limiter and 
verify its function in the switchgear panel.

 

Protection functions trip the signal block Tripping coil supervision function.
