## Peak Reading Voltmeter Circuit

Peak Reading Voltmeter Circuit: Sometimes it is enough if the Peak Reading Voltmeter Circuit of an impulse voltage wave is measured; its waveshape might already be known or fixed by the source itself. This is highly useful in routine impulse testing work. The methods are similar to those employed for a.c. voltage crest value measurements. […]

## Low Voltage Arms for Voltage Divider

Low Voltage Arms for Voltage Divider: Low Voltage Arms for Voltage Divider – The mode of connection and the layout arrangement of the secondary arm of the divider is very critical for the distortion less measurement of fast transients. The L.V. arm of the divider itself introduces large distortions if not properly connected. Different corrections […]

## Mixed RC Potential Divider

Mixed RC Potential Divider: Mixed RC Potential Divider use R-C elements in series or in parallel. One method is to connect capacitance in parallel with each R′1 element. This is successfully employed for voltage dividers of rating 2 MV and above. A better construction is to make an R-C series element connection. The equivalent circuit […]

## Capacitance Voltage Dividers

Capacitance Voltage Dividers: Capacitance voltage dividers are ideal for measurement of fast rising voltages and pulses. The capacitance ratio is independent of the frequency, if their leakage resistance is high enough to be neglected. But usually the dividers are connected to the source voltage through long leads which introduce lead inductances and residual resistances. Also, […]

## Impulse Voltage Measurements

Potential Dividers for Impulse Voltage Measurements: Potential or voltage dividers for high voltage Impulse Voltage Measurements, high frequency a.c. measurements, or for fast rising transient voltage measurements are usually either resistive or capacitive or mixed element type. The low voltage arm of the divider is usually connected to a fast recording oscillograph or a peak […]

## Uniform Field Electrode Gaps

Uniform Field Electrode Gaps: Sphere gaps, although widely used for voltage measurements, have only limited range with Uniform Field Electrode Gaps. Hence, it is not possible to ensure that the sparking always takes place along the uniform field region. Rogowski presented a design for Uniform Field Electrode Gaps for sparkover voltages up to 600 kV. […]
