SF6-filled Transmitter for high voltages

SF6-filled Transmitter for high voltages

High Voltage Dividers are used to reduce high voltage signals to levels which can safely be measured by either conventional multimeters or specialized instruments such as oscilloscopes, peak voltmeters or digital recorders/analyzers. These dividers are available in different designs. The divider type depends on the voltage waveform to be measured.
