Designed for Indian operating conditions, they deliver long-term reliability in both utility and industrial applications.
An AVT Fuse (Auxiliary Voltage Transformer Fuse), also known as a PT Fuse (Potential Transformer Fuse), is a high-voltage protective device designed to safeguard Voltage Transformers (VT) and Potential Transformers (PT) against overloads, short circuits, and fault currents. It is an essential component in electrical substations, switchgear panels, metering cubicles, and power distribution systems where reliable voltage measurement and equipment protection are critical.
Power-Grid Switchgears Pvt. Ltd. manufactures premium-quality AVT Fuses that provide dependable performance under demanding operating conditions. Our products are engineered with precision, ensuring rapid fault interruption, superior insulation strength, and long service life. Whether for utility substations, industrial plants, renewable energy projects, or commercial electrical infrastructure, our AVT Fuses help improve system safety while minimizing downtime.
An AVT Fuse is connected in series with the Potential Transformer (PT). During normal operation, it allows the rated current to pass without interruption. If an overload or short circuit occurs, the fuse element melts instantly due to the excessive current, disconnecting the faulty circuit before the transformer can be damaged. This fast-acting protection reduces maintenance costs and enhances the reliability of the complete electrical network.
Power-Grid Switchgears Pvt. Ltd. supplies AVT Fuses to a wide range of industries across India. Our products are trusted for their consistent performance, superior quality, and dependable protection.
