Ultrasonic proximity sensors are electronic devices that use sound waves at ultrasonic frequencies to detect the presence or proximity of objects. They work based on the principle of sound wave reflection and measurement of the …
Capacitive proximity sensors are electronic devices used for non-contact detection of objects based on changes in capacitance. They operate by generating an electrostatic field and measuring changes in capacitance when an object enters the sensing …
An inductive proximity sensor is a type of sensor used to detect the presence or absence of metallic objects without physical contact. It operates based on the principle of electromagnetic induction. The sensor consists of …
Power transformers are classified based on several factors, including their purpose, construction, and voltage levels. Here are some common types of power transformers:
An electric arc furnace (EAF) transformer is a specialized type of transformer used in electric arc furnaces, which are industrial furnaces used for steelmaking. EAF transformers are designed to meet the unique requirements of the …
A phase-shifting transformer is a specialized type of transformer that is designed to adjust the phase relationship between the primary and secondary windings. It is primarily used in power systems to control power flow, regulate …
Rectifier transformers are specialized transformers used in high-voltage direct current (HVDC) systems to convert AC (alternating current) power into DC (direct current) power. They play a crucial role in HVDC transmission systems, enabling the efficient …
The working principle of an isolation transformer is based on electromagnetic induction and is primarily designed to provide electrical isolation between the input and output circuits. Unlike conventional transformers that are used for voltage transformation, …
Instrument transformers are used in electrical power systems to measure and protect electrical quantities such as voltage and current. They work on the principle of electromagnetic induction and are designed to transform high voltage or …
The autotransformer is a type of transformer that has a single winding that serves as both the primary and secondary winding. It operates on the principle of self-induction and voltage sharing. The working principle of …
