Why isolation transformer is used

In such cases, an isolation transformer can be used to ensure safe and sound operation. Voltage conversion If the output voltage of the UPS is different from the voltage requirement of the load, then a voltage conversion is necessary. An isolation transformer can be designed as either step up or step down to convert voltages to desired levels so that the connected loads get the required voltage.

Reduce fault current supply to loads Isolation transformer helps in reducing noise and fault current thereby ensuring the proper working of connected equipment. Isolated transformers make use of Faraday shields to get rid of noise and leakage currents. Hence it ensures the safety of the technicians doing the maintenance work.

Isolation transformers are essential where highly sensitive instruments are involved. Such instruments are most commonly used in medical field. Back Air Pressure Booster. Back Linear Ball Bearings. Back Diaphragm Coupling Rigid Coupling.

Back Air Blower Regenerative Blower. Back Data Acquisition. Back Data Transfer Unit. Back Air Compressors. Back Industrial Camera Lenses. Back Laser Marker. Shopping Categories. What is the Purpose of an Isolation Transformer? Tags: isolation transformer , transformer , what is. What are the Types of Electric Hot Knife? Since the transformers primary and secondary circuits are electrically isolated.

Hence all the transformers we use in transmission and distribution networks are called isolation transformers. What is an Isolation Transformer? Any transformer which is used to transfer signals or power is isolating because the primary or secondary is not connected by conductors instead of that it is done by induction. The transformers which have its main function to isolate circuits can be called as isolation transformers. In isolation transformer, the primary voltage value will be equal to the secondary voltage and the two windings will have the same number of turns to compensate for losses.

A three-phase isolation transformer is a 3-phase transformer, they have isolated primary and secondary windings. So the power input will be isolated from the power output. A shielded 3-phase transformer is more efficient than the 3-phase isolation transformer because it can provide protection for sensitive equipment.

When more than one shielded 3-phase isolation transformer is installed between the source and the load, it is called as cascading and improves power quality. A transformer is used in a power system to increase and decrease the voltage, for the distribution of the electrical current. Isolation transformers has symmetrical windings which is meant to decouple two circuits.
