Abstract
A high voltage phasing voltmeter comprises first and second probes. Each probe comprises an electrode for contacting a high voltage electrical conductor. The electrodes are connected in series with a resistor. A meter comprises a housing enclosing an electrical circuit for measuring true rms voltage. The electrical circuit comprises an input circuit for connection to the first and second probes and developing a scaled voltage representing measured voltage across the electrodes. A converter circuit converts the scaled voltage to a DC signal representing true rms value of the measured voltage. A peak hold circuit is connected to the converter circuit to hold a peak value of the true rms value. A display is connected to the peak hold circuit for displaying the peak value of the true rms value.
