Power transformers in India are generally built in a way that they produce a humming sound while at work. While it may go unnoticed by us while walking down the road, there are many who constantly work in environments where Transformers are present. This means that they are exposed to this sound all throughout the day, or night, or both. This exposure may result in hearing problems initially, which may ultimately result in permanent hearing loss! Even hearing protection devices may not help. To add to that, even the vibrations that come along with the humming sound, although low-level, can prove to be harmful. These vibrations are not only harmful to the people working around, but also to the machinery itself, as the constant vibration puts stress on every tooling component within the machine, thus pressurizing and damaging it. Therefore, while we can say that transformers are highly useful and efficient devices for us, they can also prove to be equally harmful. So, how can we prevent this damage?
To prevent ourselves and the environment from such damage and impairment, it is essential that we take appropriate steps. Transformers have no rotating parts like in motors or generators, yet they produce such sound. Thus, we cannot alter any such rotating parts within the device. So then, what can be done to reduce the sound and vibration? Before we answer this question, we need to understand what exactly is causing this sound. Whenever a ferromagnetic material comes in contact with a varying magnetic field, it changes its dimensions, producing a sound. This is just what happens within a transformer, because transformers are generally made up of such ferromagnetic materials. So now, what can be done?
While no parts within the transformer can be altered, we can reduce the harmful effects by adopting certain engineering controls that can help in reducing the Noise. For example, proper innovative designs and materials like stiffeners can be used while constructing the walls of the transformer tanks. Or, a noise control element can be introduced between the transformer and workers. For this, cushion padding and oil barriers can be used during the manufacturing process, which will insulate the sound of vibration, thus reducing the noise. These elements absorb and muffle the vibrations by using vibration mounts. These mounts consist of high-tension springs through which pneumatic devices use compressed liquid or air to absorb shock by either filling or emptying a cylinder support. In this way, any unnecessary wear and tear of the machinery, or risk of workers’ hearing impairment can be eliminated.
Apart from these, there are many other solutions that can level electrical equipment and dampen vibrations, thus reducing noise.
