We can check any transformer with meggar for ground fault it means resistance value between winding and body. we can check insulation value between primary winding and secondary winding. If the load of transformer is getting more than its rating,,,than how to overcome this problem?
How do u know I don't have extensive experience using metering tools like meggers? What have I lost exactly? Not saying Bad's post wasn't very informative. Just commenting on it's length was all. Keep in mind the OP asked for help in "dumbing down" how to use a megger.

A megger's output voltage is not high enough to test the insulation of a high-voltage transformer if, by 'high-voltage transformer ', you mean a distribution To better understand how to perform this test, it is important to understand what a megger test does. A megger traditionally utilizes a relatively
Megger has a lots of electrical products. So, I assume you're referring to Megger Insulation resistance tester. Insulation resistance test is conducted to check the insulation resistance between the HV and LV, LV to earth, HV to earth, and it's also used to know if the transformer is properly dried after repairs.

Peter Werelius, Megger Sweden. Abstract: Measuring a transformer's DC resistance from one external terminal to another can reveal a great deal of information about the transformer. In addition to the obvious faulted winding (, an open winding or shorted turn), more subtle problems can be detected.
Megger's range of test equipment will ensure that you have the right instruments to analyse any form of electrical asset, from power station to plug.

How to Megger a Transformer eHow. Only trained and suitably competent individuals should use a Megger insulation tester. High voltage transformer test equipment Megger. Megger's comprehensive set of transformer testing tools provides a complete view of your transformer's health.
Like LSTM, Transformer is an architecture for transforming one sequence into another one with the help of two parts (Encoder and Decoder), but it differs from the previously One reason is that we do not want our model to learn how to copy our decoder input during training, but we want to learn
Megger test is also called as Insulation Resistance testing (IRT) or Portable Appliance Testing (PAT). PAT testing is specific to the UK, Australia, and some Megger testing comes from import Mega-Ohm, which is the measurement of results to look for an insulation test. Also, the company Megger
A megger will read a wire or motor windings in Megohms, where 1 Megohm is equal to 1,000,000 ohms. In order to read such a high resistance value the meter must be capable of generating a very high voltage. The smallest value that a megohmmeter can supply is 1,000 volts.
