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.

# What is the function of INF key in million megohm meter?

Answer . INF stands for infinite. This is used for measuring resistance beyond the mega ohm barrier. IE. A piece of metal. When active it pretty much just shows a dead shor

# When using a megger at 1000v and your reading is 2700 megohms is it a problem?

What is the acepable rating on a #3 wire when meggering @1000v

# How does a megger or megohm meter work?

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

# Express 33 kilohms in megohms?

33 kilohms = 0,033 megohms

# What scale of resistance does a megohm meter measure?

Mega = million Megaohm = 1000000 Ohms

# 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

# 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

# 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

# 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.

0.00002 megaohms

# What is 120 kilohms plus 2.2 megohms?

1000 kiloohms in 1 megaohm 120+2200=2320 kiloohms

# How do you convert ohm meter to megohm kilometer?

if it is ohm meter and not ohm per metre; divide by 1,000,000 to convert ohm to megaohm, then divide by 1000further to convert metre into kilometre

# Is a megohm a short circuit?

No. A short circuit would be zero ohms.

1000000 ohms

# What is the resistance value of a 2.2 megohm resistor?

A megohm is 1,000,000 ohms, so 2.2 megohms is 2,200,000 ohms, often abbreviated to 2.2M, or 2.2Mohm, or 2M2.

# What are the color bands on a resistor for 2.2 megohms?

Red, Red, Green - 225

# How much current 2.2 Megohm?

"Ohm" and its multiples is not a unit of current. "Ampere" and its multiples is. The current through a 2.2-megohm resistance is . ( the voltage across theresistance ) / ( 2,
