The transformer, as the name suggests is for transforming power from higher voltage to a lower voltage and vice-versa. In electrical engineering voltage for different functions/purposes is different; Therefore, the Transformer assumes a most important role. The importance of a transformer (distribution) is such, that it affects the general public directly as without electricity nothing moves. In order to perform, a transformer has to be tested thoroughly … [Read more...]
What is Transformer Rectifier : Working, Features & Applications
The transformer rectifier, also known as the transformer rectifier unit (TRU) has versatile applications due to its robustness and efficiency. It is mostly used in the aviation industry because of its mobility and lightweight. The transformer rectifier unit combines the characteristics of a transformer and a rectifier. With the use of this unit, a variable DC voltage is obtained from AC voltage. Initially, the AC voltage is varied to a different level … [Read more...]
What is Autotransformer : Working Principle, Construction & Applications
Autotransformer is a single winding transformer that works on the principle of Faraday’s Law of electromagnetic induction. Mostly used in low voltage range, for industrial, commercial and laboratory purposes. Also known as variac, dimmer stat, etc. autotransformer can be single and three-phase. Due to single winding, autotransformers have fewer losses, more efficient and robust. By taking tapping on the secondary side, a wide range of voltage can be … [Read more...]
What is a Current Transformer : Working Principle and Its Advantages
The current transformer (CT), also known as an instrumental transformer, is used to either reduce or propel the primary current across the secondary winding. The current produced across the secondary terminal is directly proportional to the primary winding. In high power circuits, the voltage across the primary side is scaled down to a minimum value, which helps to measure the actual AC transmission current through standard ammeter safely. In this article, … [Read more...]

The main function of this transformer is to transmit voltage pulses between windings and the load. These transformers are used for galvanic isolation (signal transmission), low-power control circuits, & the major components used in high-power SMPS. By using this transformer, amplitude … [Read more...]
What are LVDT and RVDT : Comparison and Key Differences
Linear Variable Differential Transformer (LVDT) and rotary variable differential transformer (RVDT) is an electrical transformer type sensor used to measure the linear displacement and angular displacement respectively. The circuit diagram and working principle is similar to each other but differentiated in terms of core and shaft movements inside the module. These sensors are also called as electromechanical transducer due to the fact that it yields … [Read more...]
