Types of transformers include step-up, step-down, isolation, autotransformer, and distribution transformers.
Step-up transformers increase voltage levels for long-distance transmission.
Step-down transformers decrease voltage levels for household use.
Isolation transformers provide electrical isolation between the input and output.
Autotransformers have a single winding with taps for different voltage levels.
Distribution t...
VFD stands for Variable Frequency Drive and is used to control the speed of an electric motor by varying the frequency and voltage supplied to it.
VFDs are commonly used in industrial applications to save energy and improve process control.
They are used in HVAC systems to control the speed of fans and pumps, resulting in energy savings.
VFDs can also be used in conveyor belts, compressors, and other motor-driven equipmen...
