440 volts should be as dangerous as 11,000 volts because a transformer does not dissipates power it just converts voltage into current, my question is if the power at the secondary region is the same why it is said that it is not as dangerous.
I haven't a clue as to who told you that. The lower voltage would tend to hold you to the wires, where the higher voltage would push you away. The only real difference is that the higher voltage could arc to you, where the lower voltage at the same distance would not.
440vAC is less danger comparing to 11,000vAC which arcs easily than 440vAC but both are very dangerous. Lower volttage will not break the insulation easily. Higher the voltage (500v ) means maintain higher distance otherwise it will develop arcing. The electrical shock and burning is proportional to the SQUARE of the VOLTAGE even the current is very low. 16v thru heart is fatal to humens , above 32v AC is said to be lethal .
volts give jolts amps gives cramps
You are correct that a transformer does not, ideally, extract any energy from the system. However, it's not always so straightforward to get the energy from the secondary into, say, a person. If the wires from the 440V secondary touched my clothes, I'd probably be safe because the cloth will insulate me from voltages like that, and thus no current will go through me. But if the wires from the 11kV side touch my clothes, the cloth will break down electrically under that high potential, allowing the current to go through me and fry my entrails.
The most common purpose of a power electronic transformer is to convert alternating current (A.C.) power from one A.C. voltage (or current) to another A.C. voltage (or current). Another common purpose is to provide electrical isolation between electrical circuits. Power is the product of voltage times current. Power transformers do not change power levels except for parasitic losses. Input power minus parasitic power losses equals output power. Ideal power transformers have no losses, hence output power equals input power. Increasing the output voltage will decrease the output current. Electric utilities prefer to transmit electricity at low current values to reduce resistive losses in the power transmission lines. Lower currents also permit smaller size transmission cables. A power transformer is used between the generating equipment and the power line(s) to step-up (increase) the transmission voltage (to high voltage) and decrease the transmission current. Distribution transformers, which are power transformers, are used to step-down (decrease) the voltage to voltage levels needed for industrial and household use
