Isolation transformers are used in many situations where isolation is desired or required. The most common application is where an electrical fault could prove catastrophic, such as during a power outage or medical emergency. These transformers can also provide a neutral path through the secondary winding, allowing for a single-point ground in three-phase systems.

REASONS FOR USE OF AN ISOLATION TRANSFORMER Requirement for strong grounding for the loads 1 Sometimes, the grounding system of the UPS may be a highly resistant one whereas the loads connected require a very solid grounding. 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. It 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. 2 Reduce fault current supply to loads 3 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. Easy maintenance of UPS An isolation transformer kept external to UPS makes maintenance of UPS easy. Isolation of UPS from the power source prevents risks of electrical shocks during the testing or service of the UPS. Hence it ensures the safety of the technicians doing the maintenance work. 4 #shaktielectricalcorporation
