🎗🎗🎗Why Do We Use a VT Fuse Failure Relay? In modern power systems, Voltage Transformers (VTs / PTs) play a vital role by supplying accurate, scaled-down voltage signals to protection relays, metering, and control circuits. Any loss or distortion of this voltage input can result in relay mal-operation, leading to unnecessary tripping-or worse, failure to trip during actual system faults. This makes VT Fuse Failure Supervision an essential protection feature. ✨️✨️What Is VT Fuse Failure? VT fus
