Use a voltage divider and an standard high input impedance voltmeter connected to the low voltage output tap of the divider. Just check that:
a) the voltage divider has enough resistance to minimize loading of the voltage source (The voltage divider resistance should be as high as possible).
b) the voltmeter's input impedance is at least 10-20 times larger than the output resistance (impedance) of the divider. If necessary add a high-input impedance amplifier or a transducer between the divider output and the voltmeter.

Can you measure ac mains voltage with dc voltmeter or high dc voltage with ac meter?
You cant.
Which will normally have the larger resistance a voltmeter or an ammeter?
A voltmeter has the large resistance.The voltage across any component can be measured if & only if the terminals of that component will be open and this will we can acheiv if we connect the high resistance voltmeter across the open terminals of that component to measure the voltage.
Voltage is measured with?
Voltage is measured with a voltmeter.
What is instrument specially designed to measure voltage?
The Ammeter XD
What is the function of capacitor voltage transformer at the switch yard?
function of capacitive voltage transformer is measure high transmission voltage with low range voltmeter and oprate the relay circuit to oprate CBs.
How is voltage measured?
Use a voltmeter with a high input impedance and measure at the source the voltage.
What does a voltmeter measure voltage in?
A voltmeter measures voltage in volts.
Can you measure ac mains voltage with dc voltmeter or high dc voltage with ac meter?
You cant.
How voltage is measured in potential transformer?
By connecting a voltmeter across the secondary terminals of the voltage/potential transformer. The transformer acts to reduce the voltage applied to its primary winding, while electrically-isolating the primary (usually high-voltage) circuit from the voltmeter.

What is the use of universal high resistance voltmeter?
A voltmeter must have a very high resistance to measure voltage. A voltmeter is placed in parallel with the element that you are measuring. If the voltmeter has a low internal resistance, then all of the current will flow through the voltmeter instead of the element. You want all of the current to flow through the element, to get an accurate reading of the voltage. Conversely, an ampmeter must have zero resistance, because it is placed in series with the element.
Voltage is measured with?
Voltage is measured with a voltmeter.
Can a voltmeter increase its voltage?
no
Can a voltmeter increase voltage?
No.
What is a voltage transformer and mention its function?
A voltage transformer (known as a 'potential transformer' in North America) is classed as an instrument transformer. It is used to reduce the voltage across a high-voltage load to a value that can be read (usually remotely) by an ordinary a.c. voltmeter, while electrically isolating that voltmeter from the high-voltage system for the purpose of safety. It can also be used to supply an input to a protection relay.
Why is a voltmeter used rather than a potentiometer?
A potentiometer is a variable resistor, while a voltmeter is a device that measures voltage.
Why does voltmeter practically not consume any electric energy from the electric circuit?
The resistance used in a voltmeter is extremely high when measuring voltage, which is why the current is low (I = E/R).
