## How to read a digital voltage in circuitry?

So a logic chip is another way to read a digital voltage signal. Another way to read a digital voltage signal is through a microcontroller such as an arduino microcontroller. An arduino microcontroller is equipped to be able to read or write HIGH or LOW digital signals.

### What happens when voltage is greater than 2.5V?

If the voltage at the inverting terminal is greater than at the noninverting terminal, the output goes low and turns on. So, in this case, if the voltage at the inverting terminal is greater than 2.5V, then the output turns on. If the voltage is less than 2.5V, the output is HIGH and the output device is off, in this case an LED.

What should the voltage be for an overvoltage fault?

Comparing Overvoltage trip thresholds with the nominal DC bus voltage we can see that the overvoltage trip settings for most drives is 130-150% of nominal DC bus voltage. Corresponding AC voltage at which overvoltage fault occurs can be calculated by dividing the above values by 1.35.

Can a logic chip read a digital voltage signal?

So a logic chip, such as a NAND gate, can be used to read a digital voltage signal. Based on whatever logic chip you are using, whether a NAND gate, AND gate, OR gate, etc determines what the output will be for a given input. Based on the logic of the logic chip being used determines the output.

## What kind of voltage is an unexpected voltage?

Unexpected voltage. Just to recap, a “phantom voltage” is where a wire from a switch to a light or outlet runs next to a permanently live wire, when the switch is off, the AC voltage in the other wire can induce a voltage in the switched-off wire.

### How is it that there is continuity and a voltage reading?

Having the breaker closed means it is acting like a switch that is turned on. Checking from one side of it to the other will naturally show continuity. One verifies the state of a breaker by looking for voltage between the hot lead and its associated neutral.

How to check for voltage fluctuations in house?

Visit #1: Technician comes out, checks voltage at meter. Monitors voltage for a few minutes, no problems arise then leaves. Declares no problems on their end. I start watching the neighbors house to see if they are getting any power fluctuations.

How to check unexpected voltage with switch turned off?

You need to check leakage voltage in your building, Check proper earthing, it might resolve your issue, otherwise, check wire connection once again, Faulty MCB will also make issue, Check MCB (OLP), i found these kind of issues in Table grounding.
