Direct measurement of Voltage in high voltage system is not possible because of insulation problem of measuring instruments. It is also not possible to use voltage through the system directly for protection purpose due to its high value & high insulation problem. In such conditions voltage transformers are used.
BASIC FUNCTIONS OF VOLTAGE TRANSFORMERS ARE . . .
To reduce the line current to a value which is suitable for standard measuring instruments, relays etc.
To isolate the Measuring Instruments, Meters, Relays etc. from high voltage side of an installation.
To sense abnormalities in Voltage & give Voltage signals to protective relays to isolate the defective system.
Direct measurement of current in high voltage system is not possible because of insulation problem of measuring instruments. It is also not possible to use current flowing through the system directly, for protection purpose due to its high value & high insulation problem. In such conditions Current Transformers are used.
