Audio Frequency Transformer: Audio Frequency Transformer is used at the output stage of Audio Frequency electronic amplifier for matching the load to the output impedance of the power amplifier stage.…

Current transformer and Potential transformer: These Current transformer and Potential transformer are designed to meet the specific need of measurement and instrumentation systems, which accept voltages in the range of…

Three Winding Transformer: Three Winding Transformer may be built with a third winding, called the tertiary, in addition to the primary and secondary. Various purposes which dictate the use of…

Parallel Operation of Transformer: When the load outgrows the capacity of an existing transformer, it may be economical to install another one in parallel with it rather than replacing it…

Variable Frequency Transformer | Application: So far we have considered transformers which operate at fixed frequency (50 Hz). Their purpose is to transform electric power from one voltage level to…

Transformer Efficiency Formula: Power and distribution transformers are designed to operate under conditions of constant rms voltage and frequency and so the efficiency and voltage regulation are of prime importance.…

Per Unit System: While carrying out the analysis of electrical machines (or electrical machine systems), it is usual to express voltage, current, VA and impedance in Per Unit System (or…
