You can measure high voltage by using Potential Transformer (PT). or by using utility meter or power manager.
ANSWER: Adding a hi resistance in series with a low resistance and measuring that voltage drop. If the resistance is known then current is determined and the source can be calculated. Transformers do not work well with DC,

What is meant by the terms 'active high input' and?
'Active high input' refers to a signal or input condition that is considered "active" or "on" when the voltage level is high, typically close to the supply voltage. This means that when the input receives a high voltage, it triggers a response in the connected circuit or device. Conversely, 'active low input' signifies that the input is active when the voltage is low, usually close to ground level. In this case, a low voltage level triggers the response.
What is input offset voltage and how to measure practically?
Input offset voltage is the differential DC voltage that must be applied between the input terminals of an operational amplifier (op-amp) to make the output voltage zero when the inputs are shorted together. Practically, it can be measured by connecting the op-amp's inputs together and monitoring the output voltage with a multimeter; any non-zero output indicates the presence of input offset voltage. Another method involves using a precision voltmeter to measure the voltage directly across the input terminals while ensuring the output is at zero volts.
How do design a high voltage voltmeter?
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. What is high voltage for you?
How do you measure the current and voltage in high tension line?
To measure high voltage use suitable instrument transformer (potential transformer) Very carefully. It can kill you. The higher the voltage the more the danger or arcing over even when two conductors are not touching. Voltage meters are rated and the rating should not be exceeded. Depending on the voltage you will need the proper meter and a high voltage probe rated for the voltage you are measuring. If you don't know what you are doing, don't mess with high voltage. Leave to the pros.

What is line regulation?
Line regulation is a measure of the ability of the power supply to maintain its output voltage given changes in the input line voltage. Line regulation is expressed as percent of change in the output voltage relative to the change in the input line voltage.
How do use a volt meter?
1. Attach the positive input terminal lead to the positive end of the circuit (or whatever you want to measure the voltage of). 2. Attach the negative input terminal lead to the negative end of the circuit (or whatever you want to measure the voltage of). The voltmeter will turn itself on and measure the difference between the voltage at the first point and the voltage at the second point, telling you how much voltage is traveling between the two points so that is how to use it effectivelly.

Why is a Schmitt trigger called a regenerative comparator?
A Schmitt Trigger is a comparator, because it compares its input voltage to a "threshold" voltage, but it has _two_ threshold voltages (the upper and lower trigger voltages), and which threshold voltage is used depends on the output state. If the input voltage is higher than the upper trigger voltage, the output will be high (for a non-inverting Schmitt trigger). In this state, the input is compared to the lower threshold voltage, so the input now has to go below the lower threshold voltage before the output will go low. The threshold voltage depends on the output state, such that a high output selects the lower threshold voltage, and a low output selects the upper threshold voltage. This can be visualised as using a fixed threshold but adding a small voltage (the difference between the upper and lower threshold voltages, also called the hysteresis voltage) to the input voltage before it is compared. This small added voltage is high when the output is high, and low when the output is low. A small amount of the output voltage is effectively being added to the input voltage before it is compared to a fixed threshold. This is positive feedback, also called regenerative feedback. So a Schmitt trigger operates as a voltage comparator, and a small amount of the output is added to the input, so it uses positive or regenerative feedback.

How a zener diode is used in voltage regulator under both varying input and varying load condition?
In the varying input condition, the zener diode is used in such a that any variation in the input voltage,should not in any affect the load (that is the arrangement supplies just the voltage needed by the load no matter how high or low the supply voltage might go). In the varying load condition, the zener diode is connected in such a way that any change in the load voltage should not affect the input voltage.
