You cannot use an ordinary multimeter to assess the difference between a normal power transformer winding and a shorted power transformer winding. You need a Q meter and/or to power it up at a reduced voltage with limited current to see what happens. Note that a shorted power transformer is capable of exploding, so you need to take appropriate safety precautions.

It generally reads RMS value of the voltage being measured
It indicate how well the input transformer is being utilized. It is given by the ratio of DC output power to the AC power rating of Transformer.
Actually current transfomer is step up voltage transformer n step down current transformer as current transfomer is having single primary turn of thick conductor but having more number of secondary turn of thin wires..so wkt tansformer ratio k= n2/n1=v2/v1=i1/i2. so it steps up volatge n steps down current...so we use current transformer as a step up transformer almost in all generating stations. Current transformers typically have terminals for a voltmeter on their case and a hole through that case. If you run your current carrying lead through the hole and connect an appropriate voltmeter (the voltmeter's design and resistance may affect the results) to the voltage terminals, the voltmeter will indicate the current in the lead times some factor which should be marked on the current transformer. If you thread the current lead through the hole N times then the voltmeter will indicate N times what it would read with the lead going through once (assuming that the ampere turns resulting do not cause saturation of the transformer's core.
Depending on the value, it varies. Using a multimeter set for Kilohms resistance, check that it appears open circuit. This may be hard to determine, due to other components in circuit. It should NOT show zero resistance. Electrolytic capacitors above 1 microFarad will show some storage of charge. Using the meter with the probes one way, there should be a percepible rise of resistance. Reverve the leads and you should get an intial negative value followed by a slow rise in resistance. If there is no perceptible rise, it could be open circuit. If it shows Zero, it will indicate a dead short.

On a multimeter, a high resistance would indicate a high Ohmic value and a low resistance would indicate a low Ohmic value. Specific values would be relative to device you are measuring.
The terminals H1 and H2 an a transformer indicate the primary side of the transformer. The secondary side is usually identified as X1 and X2.
Set the multimeter for the "buzz" mode. This mode checks for electrical continuity. This means that the multimeter checks to see if there is a path for electricity to pass through. Some multimeters indicate it with a buzz, others with a light. Put one lead at either end of the fuse, and if the indicator (buzz or light) goes off, the fuse is good. If it doesn't go off, the fuse is broken. If you don't know how to set your multimeter on that setting, or it does not have one, set the multimeter to measure resistance. If the fuse measures a really small resistance, it is good. If it measures at a really large resistance, it is broken.
You will need a multimeter and instructions on how to use it.
A Multimeter is an electronic instrument, every electronic technician and engineer’s widely used piece of test equipment. A multimeter is mainly used to measure the three basic electrical characteristics of voltage, current, and resistance. There are two types of multimeters: Analog Multimeter: The Analog Multimeter or VOM (Volt-Ohm-Milliammeter) is constructed using a moving coil meter and a pointer to indicate the reading on the scale. Digital Multimeter: We mostly used a multimeter is a digital multimeter (DMM). The DMM performs all functions from AC to DC other than analog. It has two probes positive and negative indicated with black and red color as shown in the figure. there are some best multimeters for HVAC.
It usually stands for open loop, another way of saying there isn't continuity. Original answer: it means OVER-LIMIT beyond the limits of the meter to register, such as "infinity" on a resistance scale
transformer action doesn't depend on power factor that is why we indicate its rating in KVA
It generally reads RMS value of the voltage being measured
yes the R-value does indicate resistance to heat flow
yes the R-value does indicate resistance to heat flow
voltage in a circuit (also known as potential difference p.d.)A voltmeter or multimeter is an electrical instrument capable of measuring voltage, current, and resistance. Digital multimeters have numerical displays, like digital clocks, for indicating the quantity of voltage, current, or resistance. Analog multimeters indicate these quantities by means of a moving pointer over a printed scale.
