Overview
The “Fuse failure supervision (VDSPVC)” function is designed to detect fuse failures or faults in voltage measurement circuit, based on phase wise comparison of voltages of main and pilot fused circuits. VDSPVC blocking output can be configured to block functions that need to be blocked in case of faults in the voltage circuit.
For more detailed information on “Fuse failure supervision (VDSPVC)” function, refer to ABB, Relion 670 Series manuals.
