From where does the sound coming and how manufacturers of distribution transformers India solve this problem. You will find out in this post. Read the article to know more.
Magnetostriction is the real cause behind the noise in transformer. A transformer device emits low-frequency, tonal noise that irritates public a lot. Core noise is created with magnetostriction of the limitation of core when a magnetic field is passed through them. When this happens, it causes air columns to be formed in the spaces available between the transformer core and the low voltage windings of the core and other adjacent components of the transformer. These air columns are responsible for humming noise as it moves between several parts of the transformer. The noise is also created by FAC transformers due to the energizing of the core by the alternating voltage applied to the windings and also by the fans in the transformer forcing air through the coils. The humming sound of the transformer also caused by the vibration that happens when the load current passes through the windings, interacting with the leakage flux it develops. Professionals determine this load noise level by the size of the load current. Control of transformer sound transmission Acoustical absorbing material needs to be mounted on reflecting surfaces in order to lower the sound reflection and possible amplification. You must mount the transformer on a firm support that has a great mass as much as possible. You can use vibration pads under the transformer to reduce transmittal of sound. Manufacturers of transformers are designing specialized isolation pads that you can install between the transformer and its mounting surface. This will lower the vibration in the transformer. You need to test and commission initially and ensure that the shipping bolts, packing materials, and resilient mounts to keep the sound at a minimum. Removal or loosening of the shipping bolts will result in a smooth transfer of vibration and also help in noise reduction generated by the transformer.

How Increasing Cost and Performance Pressure Influence Transformer Oil Purification Method?10/10/2016 The increasing cost and performance pressures are putting impact on several operators to enhance the utilization capacity of their transformers and transformer oil purification techniques. The use of aged transformers and network couplers is done moderately at higher rates and in several cases, they are leveraging nominal power for the first time. At the same moment, operating down times scheduled for maintenance have been reduced or fully eliminated.
The increasing load has resulted in extreme rapid ageing of insulating transformer oil and the solid insulation. This further causes drastic degradation of the dielectric properties of the insulating oil that severely affect the reliable transformer operation. There are technologies available today that help professionals to clean contaminated transformer oil and restore its dielectric properties. They have started performing sort of processes with oil filtration plant in which oil is circulated continuously through regeneration columns. The contamination absorbing agents are highly effective that easily absorb polar impurities and degradation products present in the aged transformer oil. The filtered or treated transformer oil flows back into the transformer. This cycle is performed depending on the transformer size and the ageing condition of the insulating oil for many days or weeks. Benefits of such technology are as under:
Why any transformer ages? The moisture is a true enemy of every transformer. It leads to oil-cellulose insulation by combining oxygen and temperature, which further results in chemical degradation formation of peroxides, acids, etc. This further increases the ageing of transformer and also promotes dielectric degradation. The dielectric degradation results in lightning and switching impulses, short circuits, and insulation failure. Oil regeneration is best over an oil change because:
Transformer oil purification/ regeneration and filtration is the best thing ever happen to the industries. They can now make judicial use of their money and save natural resources with this technology. Users of transformers know the significance of oil analysis. It is a method used for monitoring the engine condition, turbines, and other oil lubricated equipments like transformers. The analysis of transformer oil offers information about the condition of oil and also determines issues like arcing, aging insulating paper, and other latent faults to promote cost-effective electrical maintenance program. Transformer oil filtration is a task and before that, analysis of transformer oil is done by pro teams. How an analysis of transformer oil can help in achieving reliability for transformer? The way of maintaining transformer has evolved over the past 20 years. Now the professionals don’t just have necessary items but entire strategic tool in the management of distribution networks and electrical transmission. Extreme reliability of transformer is achieved when user fixes its every small fault and makes it operable without safety risk involvement. Though we know that replacing of transformers on regular basis is an expensive thing, but you can escape from such circumstances by maintaining the transformer properly to enhance their life expectancy. When a user precisely monitors the coil condition, he will encounter some faults in time that he can fix and outages can potentially be avoided. Moreover, he can opt for efficient approach to maintain and determine optimum intervals for replacement. Some of the checks are very simple to perform –
Once measuring of physical and chemical properties of oil, user can determine the concentration of certain dissolved gases and other problem conditions connected with either oil or the transformer. Here are few casual tests to perform on electrical insulating oils-
In this way you can analyze the transformer oil condition and perform on line transformers oil filtration process for precise cleaning of oil or fluid.
