Megger test
On the whole megger testing is non destructive. What happens is a DC voltage is applied to the device or winding under test. It is an insulation test to see is the insulation has been injured in any way to cause a short circuit when normal power is applied to it. On my megger there are 3 ranges 300V, 750V, and 1000 volts. Applying the proper voltage is essential to not damaging the device you are testing. Working voltages up to 240 volts should use the 300 range. Working voltages up to 600 volts use the 750 volt range and working voltages above 600 use the 1000 volt range. As you can see if you used the 1000 volt range on a device that had a working voltage of say 24 volts you could damage the insulation just by testing it. So meggering a device is non destructive if you use the tester as its instructions tell you to.
A megohm meter is used to test motor or transformer windings. It is used by placing the leads from a terminal to ground or between phases in a multi phase system. there should be no connection (OL) between the two.

How do you use a megaohm meter?

Answer . The same way as an OHM meter. You are measuring resistance in OHMs.. However, this meter measures a higher scale of ohmage. It is used for checking insulation which should always have high ohmage (high resistance).. The upper scale of high ohmage is marked on the meter as "infinity" o (MORE)

How do I use a clamp on amp meter?

Answer 1 When electrical current flows through a wire [or any conductor[, it creates an electromagnetic field which the clamp on Amp meter is disigned to detect and quantify. The meter loop is hinged and movable in order to open the loop to allow the loop to be placed "around" a single conductor. I (MORE)

What is a pH meter used for?

It is used to measure how acid or basic a solution is. pH ranges from about -1 to +14 though the range of a pH meter is from about 0 to 13.5. The pH of water is 7.0.

How does a megohm meter work?

The megohm meter (or megger) passes the 500, 750, 1000 volts to the wire that needs to be checked. According to ohms law R=V/I, the current in the returned voltage is measured and divided by the resistance (inside the meter). So when the current is high (i.e not properly insulated or leaking), the r (MORE)

What does 10 megohm input impedance mean?

10 megohms is the resistance through which 10 volts would push 10 microamps of current. Input impedance is the resistance seen by a signal source when connected to the input Often, this means there is a 10 megohm resistor in series with the input going to a virtual ground on an opamp circuit. 10 me (MORE)

How do you use volt meter?

Assuming you have an analog voltage meter with a dial in the center: 1. There should also be an option for DCV or ACV. If you are measuring a Direct Current, use the DC side. If you are measuring Alternating Current, use the AC side. You're probably working with DC if you don't know how to use a vo (MORE)

2.2 megohm resistor to amperes?

The question does not make sense. Ohms is a unit of resistance, while amperes is a unit of current. The two are not related unless a third item is given, such as volts. Please restate the question.

How do you use a dwell meter?

You hook it up to the coil and start the engine. When it is running it will give you your reading in degrees. Most cars require the dwell to be set between 28 and 32 degrees. I tend to set them at 28 because the dwell will increase as the points wear. I would disagree with the settings specified (MORE)

Is megohm more than kilohm?

An ohm is a unit of electrical resistance. A kilohm is 1,000 ohms resistance, while a megohm is 1,000,000 ohms resistance.

What job uses a meter?

Meter is the general name for any measuring instrument. Such as an electricity meter, or an odometer on your car. But if you mean the metre as in measuring systems, then surveyors, mountaineers, engineers, and so on.

How are meters used?

Meters are used to measure length or distance, among other things.One meter equates to about 3 feet 3⅜ inches.

What is meter ruler used for?

The rest of the world measures their length in meters or derivatives thereof (mm, cm, Km). Some unnamed country that still clings to their medieval units think that metric is too hard for them to learn. They use a meter ruler to look at and be afraid.

How do you use the word meter in a sentence?

ahaanomegas : You can use the word in many different ways. It depends on connotation/context Stalleg13 : In the context of a poem, meter implies a constant number of syllables in each line. Here is an example: Had I not been a reader, Had my intellect been dull, I would lack correct met (MORE)
