Normally the megger should be selected based on the following criteria.
1.Voltage rating of the megger
2.Range of the megger value
3.Manual - Hand operated analogue type
4.Auto- Digital Megger
To measure the insualtion resistance of Motor (LV Motors) Up to 500 V/1000 V Megger is sufficient
To measure the insualtion resistance of Motor (HV Motors) Up to 5000 V can be choosen
Normaly the range starts from 0.5 to Infinity meg value in the analogue However in digital the based on the least count /range of the instrument we can able to measure the insualtion value.

Why Megger have two ranges ohm and mega ohm?
If you measure a small resistance with the megger set in Mega ohm range you get a very tiny and inaccurate result, and If you measure a huge resistance with the megger set to mega ohm range it will bottom out. To get the most accurate measurements you want what you're measuring to be about the same as the scale you're using.
What do megger measure?
Megger is usually short for Mega Ohm Meter. It measures high values of resistance with good accuracy. Most often used to test insulation.
How can you reuse a zero mega-ohm megger value cable?
A zero mega-ohm reading on a megger indicates that the cable has a short circuit or insulation failure, making it unsafe for use in electrical applications. To potentially reuse the cable, you must first repair or replace any damaged sections and ensure proper insulation integrity. After repairs, retest the cable with the megger to confirm it meets the required insulation resistance standards before reinstallation. If the cable is beyond repair, it should be properly disposed of to prevent safety hazards.
What reading should you get when you mega between phases on a pump?
The term is 'megger', not 'mega', and the answer is infinity.
What is a megger watt?
A mega Watt is 1 000 000 (1 million) Watts.

How do you measure electrical insulation resistance value?
By Megger testing (meggering) of the motor any one can measure the IR of the motor. MEGGER is a device used to measure IR. Analog Megger device may generate 500 volts..it gives coil to coil or coil to body IR value...it should not be less than 2 Mega ohm, generally it should be or kept more than 5 mega ohm...thanks ...DEEPAK RAJPUT
What is a bridge megger?
A bridge megger can be used for resistance measurement and fault locationIt is so known because it measures high (mega-ohm) resistances, and uses a bridge circuit, which is suited to this type of measurement.Visit Test Equipment Connection for new and refurbished Megger Testing Equipment

Can you mega a motor with fluke meter?
No, a Fluke meter is not suitable for megger testing, which requires a dedicated insulation resistance tester or megohmmeter. While Fluke meters can measure voltage, current, and resistance, they do not generate the high test voltages needed to assess insulation integrity. For accurate insulation testing of motors, a megger is necessary to apply the appropriate voltage and provide reliable readings.
How do you check with mega that you have good grounding on electrical circuit?
when you say "mega" I am asuming you mean meggar-ohmmeternot the lottery This instrument is not appropriate to test for good grounding Good grounding requires LOW resistanceA Meggar is used for measuring for HIGH resistances You need a MICRO-ohmmeter or ground resistance meter A company called AEMC makes nice ground testers
How can you find out if your electric cable damaged in a house?
A skilled repair man can use a tool called an Megger(mega-ohm meter) to check the condition of the insulation.
Why you use mega ohm resistance in small electronics circuits?
Each resistor in a circuit performs a well defined function and its resistance is calculated by the circuit designer as the voltage across it divided by the current through it. Sometimes the value of resistance required is over 1,000,000 hms.
How does 1 mega ohm looks on a megger device?
On a megger device, 1 megaohm will typically be indicated on the display or dial as "1 MΩ" or "1.0 MΩ." Depending on the specific model, it may be shown as part of a range or scale that includes other resistance values. The reading will be steady if the insulation is good, and a higher reading indicates better insulation quality. If the reading fluctuates or shows a value significantly lower than 1 MΩ, it may indicate insulation problems.
