When it comes to buying a transformer, there are so many options you can choose from. It is important to understand that the complex aspects of power distribution make the process of choosing just the right transformer for your business even more challenging. You have to make sure that your new installation is compatible with the equipment you are using as well as adhering to the safety standards as spelt out under the operators manual. Currently, the changes in technology and way of doing things have led to a major shift in the mew UPS system designs that are transformerless. This means that when incorporating this system design, you just need to find a convenient location and you will most definitely get the desired results. The best example of UPS system designs is the portable isolation transformer. Generally, the portable isolation transformer is used for the transfer of electrical power from an AC source (alternating current)) to a different device. During the process, the powered device is isolated from the power source mostly because of safety reasons.
Simply out, a portable isolation transformer is meant to provide specialized functions. This is the reason why a portable isolation transformer is a common installation in industries that provide power to sensitive devices or equipment. When it comes to the troubleshooting, testing and servicing of a portable isolation transformer, there has to be some safety precautions that should be undertaken. For example, the flat wire power cable of an outlet is connected directly to the ground. This means that any equipment that is nearby and that is grounded such as the concrete floor, lamp, desk or the oscilloscope ground lead will be at risk from the hazardous potential difference in relation to the temporary power restoration devices. When you use a portable isolation transformer, the bonding between the transformer and the ground is eliminated meaning that the shock hazard is contained to its entirety within the device.
Types and Application Areas
There are several types of portable isolation transformers in operation today. You can have a marine isolation transformer, a medical isolation transformer or a toroidal isolation transformer. In terms of application, isolation transformers are mostly used to protect devices or equipment that is sensitive hence the need to be protected from the noise from the grid. The connection process is that the monitor of the sensitive device is connected directly to the isolation transformer before connection to the UPS is done. A large percentage of UPS units are of the type that is referred to as ‘buck and boost’. This means that the UPS units have their battery floating under the same angle as the rectifier inverter as opposed to being connected in a series kind of manner to the rectifier and the inverter. In terms of safety, isolation transformers are very effective when working with AC equipment. Ideally, you are less likely to experience any shorts in the circuit as the working principle of a portable isolation transformer is mutual induction.
