AC DC High Voltage Meter Capacitive Voltage Divider Electrostatic Voltmeter

Excerpt on Voltage Divider

 

In electronics, a voltage divider (also known as a potential divider) is a passive linear circuit that produces an output voltage (V_out) that is a fraction of its input voltage (V_in). Voltage division is the result of distributing the input voltage among the components of the divider. A simple example of a voltage divider is two resistors connected in series, with the input voltage applied across the resistor pair and the output voltage emerging from the connection between them.

Resistor voltage dividers are commonly used to create reference voltages, or to reduce the magnitude of a voltage so it can be measured, and may also be used as signal attenuators at low frequencies. For direct current and relatively low frequencies, a voltage divider may be sufficiently accurate if made only of resistors; where frequency response over a wide range is required (such as in an oscilloscope probe), a voltage divider may have capacitive elements added to compensate load capacitance. In electric power transmission, a capacitive voltage divider is used for measurement of high voltage.
 

 

Principles of Operation

 

Digital high voltage meter consists of two parts: voltage divider and digital voltmeter. The voltage divider is a passive resistive-capacitive voltage divider, which is composed of high-precision low-temperature-drift resistor and precision capacitor. The digital voltmeter consists of true rms circuit, peak measurement circuit and digital display. Voltage divider and digital voltmeter with coaxial cable connection, high voltage through the divider voltage divider sampling sent to the digital voltmeter, through the function switching button, respectively, the detection of the corresponding value and display in the digital display, can be read out directly measured DC, AC RMS, AC peak and AC voltage. The instrument is easy to operate and has high measuring accuracy.

Problems and Solutions

 

Problem	Solution
Test results are too much deviation.	Check whether the coaxial cable is well connected.
There is more obvious discharge sound when measuring.	Check whether the ground is good.
	HV divider may be damp, Please wipe the shell with a dry cloth and then blow it for five minutes with blower.
