Errors in Potential Transformer : The potential transformer also introduces the ratio error and phase angle error just like the current transformer. Ratio Error : Due to a change in load conditions in the distributi…
The working principle of induction motor is similar to transformer i.e., the primary and secondary windings of a transformer are referred to as stator and rotor in case of induction motor. The transformer works on the princ…
A transformer is a static device, that transfers electrical energy from one circuit to another without any physical connection. It works on the principle of magnetic induction, which induces emf in another circuit by means…
In the last article, we have seen about construction and working of a current transformer . A current transformer is a special-purpose transformer used to measure high currents in transmission and distribution systems. But …
A phase-shifting transformer is a special type of transformer used to control active or real power flowing through a multi-network power system. It is used to stabilize power flow and balancing the loads in the power system…
Generally, transformers are used to transfer generated voltage at the generating stations to the various loads. Transformers do this by stepping up the voltage at generating stations and transfers this high voltage to the l…
It is important to monitor current and voltages at the substations and generating stations which are at high values. In dc circuits it is easy to measure large currents by adding suitable shunts to the low range ammeters. W…
A transformer is a stationary ac machine used to raise or reduce the voltage levels. There are different types of transformers based on application. A transformer can be single-phase or three-phase. In this article let us s…
Necessity of Transformer Cooling : When the transformer is working or on-load or supplying or delivering current there will be some iron loss and copper loss takes place continuously. If the transformer works continuously…
