Isolation Transformer is a transformer Used to switch electric energy from a supply of alternating current (AC) energy to a few system or tool whilst keeping apart the powered tool from the energy supply, generally for protection reasons. Isolation transformers offer galvanic isolation; no conductive route is gift among supply and load. This isolation is used to guard in opposition to electric powered surprise to suppress electric noise in sensitivity with unique insulation among number one and secondary and is specific to face up to a excessive voltage among windings.
Isolation transformers block transmission of the DC issue in indicators from one circuit to the alternative however permit AC additives in indicators to pass. Transformers which have a ratio of one to one among the number one and secondary windings are frequently used to guard secondary circuits and people from electric shocks among energized conductors and the earth`s floor. Suitably designed Isolation transformers block interference because of floor loops. Isolation transformers with electrostatic shields are sued for energy materials for touchy system together with computers, clinical devices, or laboratory instruments.
Applications of Isolation Transformers:
a) For preventing data corruption and failure in computers using hard disc.
b) For the protection of telecommunication and data communication equipment
c) For the patient’s safety while using machines like ECG, EEG or EMG pacemakers or any electrosurgical aid.
d) For clear recording in audio and video recording equipment.
e) For error free data in process control instruments.
f) For elimination of earthing problem in electrical installations.
g) For protection of CNC/ PLC equipment from surges / spikes.
