Meggering, or insulation resistance testing, involves using a megohmmeter to measure the resistance of electrical insulation. To perform a megger test, first ensure that the equipment is de-energized and safely isolated. Connect the megohmmeter leads to the conductor and ground, then initiate the test by pressing the test button; the device applies a high voltage and displays the insulation resistance value. After testing, ensure to discharge the circuit and reconnect any removed connections.
Take it apart and burn the insulation out, if you can, in a pile of brush. Or you could also take a torch to it and see if that gets the insulation out. If you use flame to melt the copper, beware of toxic fumes from burning rubber and plastic insulation.
if we remove a resistor from the parallel connection the effective resistance value will be increased.
A: Nothing it just quit delivering power and sit at idle current
The secondary voltage (output voltage) of a transformer depends on the turns ratio of the transformer, and is limited by the practical insulation levels of the secondary winding, so can be very high indeed. Power transformers used in electricity transmission systems have secondary voltages in the range of hundreds of kilovolts.
explain why all the load must be removed when to conduct the insulation and resistance testing

Probably the insulation from the wire, if this is the train of thought that you are thinking.
No, the total resistance increases.
170 mph
Removes solder from electronic components so that they can be removed from the circuit board
when all the resistance removed from the circuit
Mill scale can be removed by sandblasting utilising high air pressure sandblasting equipment.
heat the other side of the door if you can & scrap off - it does work, we removed the insulation from aluminum sheeting that way
A television if first and commonly considered a furniture fixture. If the television is used in an office atmosphere for work requirements, it can also be considered office equipment.
