Distribution transformer is one of the widely demanded transformers in the market due to the excellent performance exhibited in various industrial application areas. After the analysis of the requirements of the industrial sectors, the distribution transformer is categories in four different categories in the basis of factors. On the type of insulation, the array includes dry-type distribution transformers or liquid-immersed distribution transformers, and on the Basic impulse insulation level (BIL), the array includes transformers for medium-voltage, dry-type applications. The number of phases is also the factor responsible for the categorisation of the distribution transformer like single-phase distribution transformers or three-phase distribution transformers. Low voltage distribution transformers or medium voltage distribution transformers are also the categories of the distribution transformers that is divided on the basis of voltage class only for the dry-type models.
Installation of the Distribution transformer in correct environmental conditions and using international standards set by ANSI, NEMA, and IEEE, is important to ensure flawless performance. With proper guidelines, one can avoid various hazardous accidents and malfunctioning of the transformer. Before connecting the transformer, it is very necessary to check the setup in order to minimize the probability of any safety hazard. The installation procedure is very complicated and common thus, when sizing Over Current Protection Devices (OCPDs) and bonding and grounding conductors the confusion is created. Thus, installation of some of the variants of the distribution transformers may be a challenge in terms of NEC requirements. Thus, the components of the transformers are manufactured precisely as per the set norms. The distribution transformer complying perfectly with the international paradigms has to be installed properly so that any hindrance n the performance is eliminated.
Below mentioned are some of the guidelines to be followed while installation of various types of distribution transformers. Thus, these practices help the proper functioning of the transformers and avoiding various hazardous conditions.
Before installation, it is very necessary for the expert to look the location for various parameters. The Permanent Grounding, Humidity, Fluid Inspection, Pressure Maintenance, Inspection and Filling, and Loading are some of the factors to be taken care of so that the installation procedure is as per the international set guidelines. Some other common parameters to be tested are Surge Arresters, Structural Considerations, Mounting, Protection, Ground Wires, and Guying of Poles. There are experts, who have in-depth knowledge of the distribution transformers and thus help in assuring installation of the transformers as per guidelines set by ANSI, NEMA, and IEEE.
The guidelines also include various precautions that one should observe in order to ensure successful installation of the distribution transformer. The precaution guidelines differ from transformer to transformer as the construction and categories. The Outdoor Distribution Transformers are installed keeping aside the hazards by maintaining various outside elements like Minimizing Damage, Enclosures, Soil Considerations, etc. On the other hand in Indoor Distribution Transformers the factors like Structural Integrity, Ventilation, Noise, Water, Contaminants, and Accessibility. If all these parameters are taken into consideration, then fewer hazards are assured and flawless performance of distribution transformer.
