Electrical Power Solution

Electrical Substation Now days the electrical power demand is increasing very rapidly. For fulfilling these huge power demands the modern time requires creation of bigger and bigger power generating stations. These power generating stations may be hydro-electric, thermal or atomic. Depending upon the availability of resources these stations are constructed different places. These places may not be nearer to load centers where the actual consumption of power takes place. So it is necessary to transmit these huge power blocks from generating station to their load centers. Long and high voltage transmission networks are needed for this purpose. Power is generated comparatively in low voltage level. It is economical to transmit power at high voltage level. Distribution of electrical power is done at lower voltage levels as specified by consumers. For maintaining these voltage levels and for providing greater stability a number of transformation and switching stations have to be created in ...

Dry type transformers typically feature either copper or aluminum windings, also known as coils. Transformer windings refer to the coils within the transformer that draw and distribute power inside the unit. There are typically two windings in a dry type transformer — one that draws power from the source and another that transfers that power to the load. Both copper and aluminum windings perform the same function. For some applications, one type is preferable over the othe r. The   option you choose depends on the specific needs of your facility and your unique requirements. We’ll explain more about how aluminum and copper windings compare below. Differences Between Copper and Aluminum Windings While most low and medium voltage dry type transformers rely on aluminum windings for energy transfer, many engineers and plant operators prefer copper windings for specific applications. Here are some of the primary differences between the two types: Initial Costs At the outset, aluminum wi...

When researching the  advantages of cast resin dry-type transformers , you may find the information available to be somewhat incomplete. More so, only a few of its favourable features are well known, with one of the most noteworthy being its minimal fire risk due to zero oil usage. Self-extinguishing, low fire hazard: The transformer insulation consists of an epoxy resin and quartz powder mixture (an eco-friendly material). This allows the winding to be flame-retardant, self extinguishing and almost maintenance free, eliminating the need for costly fire extinguishing equipment. It will also not produce toxic gases, not even under the effects of arcing. Zero oil usage: The cast resin transformer only needs air to cool. Therefore, it eliminates extra costs and labour for liquid-level checking, oil testing, oil recycling costs, and dielectric testing for moisture absorption. Being almost maintenance free, there are no more on-site oil leaks, which require gasket replacements. ...
