An isolation transformer is used to transfer electrical power from a source which provides alternating current to any device which is isolated from the source of power. This isolation is done for the safety of the device from anything that can go wrong in the power source. They are used in multiple facilities from hospitals to laboratories where even small faults can result in big mishaps. Isolation transformer keeps the equipment in these facilities safe and protected.
An isolation transformer uses the principle of galvanic isolation which is useful in preventing current in different devices. So, when you use this transformer there is no direct connection path but, the electricity is still transferred with the help of capacitance, electromagnetic waves and induction. When you have to protect the electric shock between the energized conductor and the ground, it is suggested that you use isolation transformers that a ratio of 1:1 between the secondary and primary windings. This device has the capability of protecting electrical devices from any faults due to fire hazards. There are four main advantages that will make you choose isolation transformer over others:
- Better Power Quality – When you employ an isolation transformer for your use, you get an overall better power quality. The power supply is also efficient because the shields reduce any chances of current leakage. This helps the devices to work to the best of their capacities.
- Safe And Secure – The biggest advantage that an isolation transformer has over others is the safety it provides. This particularly important in sensitive places such as hospitals because the equipment there is directly related to someone’s life and any fault can be dangerous for the patient.
- Less Noisy – The design of a transformer is such that it naturally reduces any noise from power lines. Their noise reducing capabilities make them a favourite for facilities where noise control is the priority. The shields that reduce noise also prevent any interruption in the power flow.
- Smooth Functioning Devices – One more advantage of installing this transformer is that they decrease power surges. DC signals from the power source are isolated and the power surges are reduced as a consequence which ensures smooth functioning of electrical equipment. In a sentence, this means that even if there are any issues with the power supply, the devices will run smoothly.
So, choosing a transformer can be really beneficial device and you should always opt for it given that it suits your requirements.
