Isolation transformer action

Isolation transformer's primary role is: to make the primary side and the secondary side is completely insulated electrically, but also so that the loop isolation. Further, using its large core loss at high frequency circuit breakers, thereby suppressing high frequency noise from the incoming control loop. Isolation transformer with the secondary suspension on the ground, can only be used in the power range of smaller, shorter lines occasions. At this point, the system capacitance to ground current is too small to cause bodily harm. There is also a very important role is to mcb circuit breaker personal safety! Isolate dangerous voltages.
With the continuous development of the power system, the transformer as the key equipment in the power system plays an Electric energy meter  role, it is directly related to the safe operation of the entire power system reliability. Transformer winding deformation refers to the force coil occurs after axial, radial of dimensional changes, the body displacement, coil distortion and so on. Transformer winding deformation caused by two main reasons: First, the operation of the transformer is difficult to avoid short-circuit fault subject to external shocks: the second is the transformer in the transport lifting process accidental collision.
