There's not a lot to go wrong in a transformer. You can test with an ohm meter (resistance meter) to check that the wires aren't broken if you know what the connections are. It will read low around 10 ohms if the wires are OK and will read very high if they aren't.
However there is a slight possibility that if it is damaged some of the wires may have shorted out so it will still read OK but will overheat when you put full power on it. So you need to power it up and check the output is what it should be with a voltmeter set on AC for a suitable scale.
Be careful not to electrocute yourself.

Difference between Izod impact test and Charpy impact test?
1) The test notches for the impact specimens for the tests have different dimensions. The Izod test is a V-notch; the Charpy test has three different specimen types: Key-hole, U-notch, and V-notch. However, other specimen types may be specified as required for both tests.2) The specimens are held differently. The Izod specimen is held in a cantilevered manner; the Charpy test is held such that the specimen rests against two supports on either side of the test notch.3) The impact location is different. The Izod test impact is against the end of the exposed cantilever; the Charpy test is struck directly behind the test notch such that the specimen undergoes three point bending.4) The test specimens have different dimensions. The basic Izod test specimen is 75 x 10 x 10mm (2.95" x 0.394" x 0.394"); the basic Charpy test specimen is 55 x 10 x 10mm (2.165" x 0.394" x 0.394")It's really a stretch to give 4 points of difference, particularly as these tests may be altered as required depending on the material performance characteristic being investigated.Source(s):Degarmo, E.

What are the symptoms of musculoskeletal pain?
CCNA tests are for people in the information technology field and they can be very good careers if you have certain certifications. You will get more opportunities with a CCNA.
Same note played on two different instruments different?
Usually the way you play the notes are different. so the answer would be yes the note is different.
What is the difference between destructive testing and nondestructive?
Destructive and Non Destructive Testing: Nondestructive testing or Non-destructive testing (NDT) is a wide group of analysis techniques used in science and industry to evaluate the properties of a material, component surface & subsurface without causing damage or effect to their future performance or properties. Non-destructive testing is used to detect abnormalities in physical, chemical or electrical characteristics. In Destructive Testing, tests are carried out to the specimen's failure, in order to understand a specimen's structural performance or material behaviour under different loads. These tests are generally much easier to carry out, yield more information, and are easier to interpret than non destructive testing. Destructive testing is most suitable, and economic, for objects which will be mass-produced, as the cost of destroying a small number of specimens is negligible.
4 different types of pulleys?
The different types of Pulley Systems include:FixedMovableCompound
What do Electrolyte tests come from?
Electrolyte tests are performed from routine blood tests
How is Wilson disease diagnosed?
The diagnosis of Wilson disease can be performed relatively easily through several different tests;
What gait is NOT performed in Dressage?
gallop is not performed in dressage tests.
How are reflex tests performed?
The examiner uses a rubber mallet to strike different points on the patient's body, and observes the response.
What are the tests called that are performed on automated laboratory equipment?
Tests performed as a group on automated laboratory equipment are known as a PROFILE.
Are high voltage tests on current power transformers recommended and if not why?
Hi-pot and megger tests are common to check the insulation on transformers, motors, refrigeration compressors, etc. They help check the condition of equipment to avoid a future falure. High votage test are conducted in current transformers by shorting the seconday and earth,can apply 3 times the rated voltage
Which types of transformers used in industries?
There are many different types of transformers used in industry. They include polyphase, capacitor voltage, and resonant transformers.
What mathematical operation must be performed to solve for primary voltage in transformers?
Division
how can i get my medical records for tests performed?
lol
Can sumpner's test be performed if the two transformers are of slightly different voltage ratios but otherwise identical?
yes you can but the resuld will be unpredictable, e.g. how will tou distribute the total powerloss in the two trasformer.
How do I find out what's causing my back pain?
There are several different tests that can be performed to help determine the cause of back pain. Some of the tests are : MRI, CT Scan, Physical Exam, Bone Scan etc.
What happen if 440V is connected to 220V transformer?
If the frequency is kept the same, you will overexcite the transformer, and it will draw excessive current (similar to inrush currents). Insulation tests are performed on transformers above nominal voltage, but they are performed at higher than rated frequency to keep the volts per hertz roughly equal to prevent overexciting the core.
