A control transformer marked 240V - 24Vac would have a control voltage of 24 volts.
When a resistance measurement is taken from both primary leads tied together to both secondary leads also tied together in a transformer, and the resistance obtained is 200 Ohms -- not safe in my book.
The primary line side of a 3 phase transformer should be marked H1, H2, H3. The line side is the incoming voltage that you want to step up or step down or isolate.
yes open all fuses close the primary neutral tap,remove secondary leads off of bad traansformer,tell customer to reduce his load until bad transformer can be replced.
I'm not sure I understand the question. If you are asking if it's single or 3 phase, this will be marked on the name plate.

The conductor for H2 connection on a 480 volt wire transformer should be marked:
To wire a buck-boost transformer from 208V to 240V, connect the 208V input leads to the appropriate taps on the transformer to step up the voltage. The output leads on the transformer will then provide 240V. Be sure to consult the transformer's wiring diagram and follow all safety guidelines during installation.
First. You should not attempt this unless you are an electrician and KNOW what you are doing. Second: Ensure transformer is rated for 480 primary and 120/240 secondary. Third: See step One... But if you insist on doing it yourself, make sure your insurance is paid up.... On the Primary side of the transformer will be leads marked H1 H2 H3 etc. On the Secondary side the leads will be marked X1 X2 X3 etc. Look on the nameplate data on the transformer. It should tell you if it is rated for 480volts and should have a wiring diagram on it... If it does not, get one that does to ENSURE that you have the correct transformer....

rectifiers have two terminals.it has a circular ring printed on its body.this terminal is negative or n type.but when you connect any terminal of a rectifier to any of the leads of transformer it works reverse.e.g if u connect -ve terminal to the transformer it will give +ve potential,so the other terminal of transformer without rectifier will give -ve potential.

To test a doorbell transformer, follow these steps: Turn off power to the transformer at the circuit breaker. Use a multimeter to check the voltage output of the transformer. Connect the multimeter leads to the transformer's output terminals. Turn the power back on and check the voltage reading on the multimeter. The voltage should match the transformer's rated output voltage. If the voltage is significantly lower or higher, the transformer may be faulty and need to be replaced.

No, the grade or alloy is not usually marked. The manufacturer's data may indicate it though.
The indicates the direction for correct installation. Bucholz relay operates when gas bubbles in the transformer oil pass through the relay in its pathway. The relay has to be installed arrow indicating upwards.
