Role of alarms in protecting transformers

Though transformers are equipped with precautionary methods to ensure plant’s performance and longevity, it is important to be updated constantly with what is happening within the apparatus. Reacting to faults is simpler when the substation crew is kept informed about the transformer’s internal function and the logic behind it. With such information, they could react

Effect of Oil Regeneration on Improving Paper Conditions in a Transformer

The transformers play a key role in the integration of the electricity grid and in the continuous operation of the electricity grid. As the world transports towards a stronger electricity grid, the dependability of each network component becomes of the major importance to ensure continuous supply of power to consumers. There is a growing interest

Drying time for transformer core

The transformer is a fixed electrical machine used to transfer power from one circuit to another. The voltage can be changed anytime as per the need of the owner or according to the situation. Usually, the transformer had four-component terminals or more to transfer current or voltage into a device. It has two sides, i.e., Primary and Secondary, with two terminals at each side.

Properties Of Transformer Oil

Dielectric dissipation factor can be termed by another names called loss factor is also accepted as the tan delta of the insulating transformer oil. When the insulating materials are located in the middle of the active section and the base section of electrical equipment, aperture current will be developed which flows through it . The insulating material which is non-conductive is offensive in nature and the current flow and therefore the flow of current through the dielectric material admirably leads the dielectric voltage by 90o.

Oil used in transformer

Transformers play a vital role in providing reliable power supply to the consumers. Without the use of transformers, the power supply network cannot be operated as much effectively.  Hence the maintenance of power transformers also have become more important.  The oil insulation used in the power transformers act as electrical insulating medium as well as a coolant for the transformer.

Transformer Oil Filtration System

The transformer oil filtration system is a method of removing the suspended sludge materials present in the oil. The impurities of the transformer oil also affects the solid insulation material and hence decreases the performance characteristics of the transformer.

Transformer Oil Regeneration and Reclamation

Transformer oil Regeneration/Reclamation is a key process in Transformer waste management and sustainability. It is the process of removing water and other oxidation by-products from the insulating oil. Transformer oil regeneration is performed on-site, either while the oil is still in the power transformer (on-load), or in barrels or tanks (off-load).

Preventive Maintenance of Transformer Insulating Materials

A regular maintenance of transformer oil involves upgradation of the oil before the dissolved gases, sludge material, moisture content and the acid formation exceeds the limiting value set by the international standards. Before the effects of all the above mentioned factors overhaul ,steps should be carried out onsite to recycling transformer oil or reclamation of the transformer oil.

Degradation of power transformer insulation materials

Power transformers are considered as important equipment of Electrical energy transmission and distribution systems. These power transformers are continuously in operation since their construction and hence their ageing process are going on towards their end of life which cannot be avoided . Due to economic factors , it is necessary to keep the current working
