Single-phase VTs are typically used in low-voltage systems and are commonly found in residential and commercial electrical systems. 

They are also used in industrial applications, such as power plants, substations, and power distribution systems.   

Single-phase VTs are designed to provide a reliable, accurate, and safe voltage measurement for metering, protection, and control functions. 

They are typically used to measure line-to-neutral voltage and are connected in parallel with the measured circuit.




What is the difference between a distribution transformer and a power transformer?
    • Distribution transformers: These are smaller units responsible for stepping down high voltage from the transmission grid to lower voltages suitable for homes and businesses.
    • Power transformers: These are larger units used in transmission and substations to step up voltage for long-distance transmission or step down voltage for industrial applications.
What factors should I consider when choosing a transformer?
    • Voltage rating: Choose a transformer with the appropriate input and output voltage requirements for your application.
    • KVA (kilovolt-ampere) rating: This rating signifies the transformer's capacity to handle the electrical load. Choose a KVA rating that exceeds your expected power needs.
    • Cooling type: Transformers come in various cooling types, such as oil-filled, dry-type, and cast resin. Consider factors like noise levels, environmental conditions, and maintenance requirements when choosing the cooling type.
