SF6-filled analysis for extra high Voltages

SF6-filled analysis for extra high Voltages

High Voltage Meters measure AC and DC voltages of up to 30kV with high accuracy. The meter input impedance is as high as 1000 M ohm, making the meter suitable for measurement of voltages of high source impedance circuits. Meters are compact and light weight and can be conveniently used as a calibration meter.

Higher the voltage, lesser is the current and lesser is the power loss (I²R) and lesser is the voltage drop (IR). Similarly the consumers do not use high voltage and so the same must be stepped down to low voltage.
